5 lug from J30 on 240sx Q's

[placham]

I see there were some few write-ups on forum about using Z32(300ZX) N/A rear 5 lug hubs.

Any one has pictures of actual hubs from a 300zx. I just want to compare them to J30 hubs. I have noticed from my research that both 300ZX and J30 use 5 lug, rear rotors, and drum brakes for rear parking.All years of 300zx N/A hub's have same part number off #4320230P11and 300zx TT part number #4320240P11All years of J30 use only one type of hub part# 432020P013And 1995 240sx rear hub for SE model part number is #4320230P11.

So all 300zx N/A and 95+ 240sx use same rear 5 lug hub. I just want to see pictures of the 300zx hub is it identical to 240sx?

Because if J30 hub is same as 300zx N/A in shape, that mean it could be used on a 240sx. Then only difference could be the axle spline hole and spline count. I have read some where that the 180sx Type-X (would be like 1997), uses rear diff with output shafts similar to skyline, ( 5 bolt flange, same as J30). Now since I have J30 VLSD (5 bolt flange) diff, using J30 5-lug hubs and axles would kill 2 birds with one stone for me. I could convert to 5-lug and upgrade to a VLSD.

Now J30's around where I live are dime a dozen, 240sx and 300zx are a rare find, and 240sx 5-lug for parts is super rare.

Hope you guys understand my incoherent jiber-jaber .

Oh by the way I got all the possible combinations for front figured out.

I will add pictures here, some one that knows is more than welcome to post;

Sorry if I used someones pictures, got them from Google.com, dont kill me. Are these 300ZX rear hubs everyone is usingor these

I think there might be other people that, might do or did this setup all ready.

Oh and while I'm at it

what are the axle nut size, J30/300zx/240sx.

[irax]

you answered your own question good for you!

the picture you posted was from a 300zx TURBO but it can be used if you press out that bolt that is sticking out.

[placham]

Those are some random pics I found on google, LOL, I knew it had something to do with 300zx and 240sx.

I have never seen a 300zx N/A or 300zx TT hubs. I know people are using 300zx N/A hubs.

But what is the difference between 300zx N/A and 300ZX TT, is it just th axle hub spline size/diameter?

Because I seen J30 set up at junkyard, and it looks exactly same as 300zx.

I want to adapt J30 hubs to 240sx and run VLSD with its axles.

So your saying that 300zx N/A hubs have that bolt/anchor pin for parking shouse? And to run it on 240sx just simply remove it, and every one is using it because it fits stock 240sx axles right?

I dont want parking shouse/disc setup. I just want 5 lug use J30 hub and axles. Is that possible to do, which rotor would I use, can I use my stock calipers?

I think this would be grate info for a How-to or write-up, comparing all these different parts, if someone is interested in doing it. And J30's are common around where I live.

_--------------------------------------------------------------------------------I haven't messed around with axles on a 240sx or J30. but from top of the head anyone remembers the axle nut for ether one? What about the rear wheel hub bolts ( the ones on back)what size are they?

[got chub]

i just skimmed over the OP and didn't read the other post so if this is you answer then good if not then don't mind me its late.

the Q45 5 lug will work on the 240 but you will need the Qs axles the spline count is different than the 240 and the NA Z

[placham]

Just checked in, I was really tired yesturday, from driving all night.

I will know today, I'm planing a trip to a local junkyard. I will get 5 lug hubs from J30, try to get axles. I have a J30 VLSD got it while back.

If Q45, works on 240sx so should J30 right. I think that some people had used Q45 VLSD (it might be same as J30) plus you get 5 lug hence you need to use that axles

And Q45 and J30 rear set up looks a like. I will check nub part numbers on ALLDATA.

>>>>>>>>>>ANY ONE KNOWS AXLE NUT SIZE FOR J30 AXLES<<<<<<<I really need to know because biggest one I got is 32MM for metric. Do I need bigger size?????????

[placham]

Okay I have update. Q45 has different axle spline size than J30, so J30 axles cannot be used with Q45 hubs.

AND THIS IS VERY IMPORTANT,, >>>> J30 does not have drop-out/bolt on hubs, they are pressed in. This is really gay, but that is how it is.

So if some one uses, 300zx hubs which is same as 240sx but with that parking brake thingy. And if you want to use J30 VLSD, you will need axles that fit axle hole like 300zx and have right bolt pattern for diff.

Unfortunately, for me I have older VLSD from J30 with 5 bolt holes spaced out.I dont know if J30 and 300zx/240sx share same axle spline size or not. but if they do that would be grate.

Than this is the set-up you would need, 2400sx or 300zx 5-lug hubs, J30 VLSD (if 5 bolt than you will need axles too) if 6 bolt with 2bolt by 3 sets (than more than likely it will bolt right up to your stock axles. I'm just reffering here to J30 VLSD but there is many more out there, do some search(who ever is looking for VLSD's)

I went a different route

Here is what a little salvage yard faery brought me today. The bolt that is sticking out in pics above (anchor pin 4 brake shouse) comes out easily, no need to press it out.Your looking at 1993 Q45 VLSD, Complete 5 lug hubs with brake shield (are the same as above pic but probably bigger axle spline hole), Q45 axles L+RBMW 740I 5 lug 15" alloys with 225/60R15 continental TiresOh yeah one set of tires came in today < they are for the front215/40R17 Falken Ziex ZE-512, Still waiting for my rears 235/40R17's.

I spent today $159.14, if you subtract the BMW wheel tire combo, it comes up to $94.39, uyeah they were like almost $60 bucks with tax. But they'r not for my any way, I got them for someone I know.

Not a bad day I would say.

I will try them on, on Saturday if I will have time. I will let every one interested know how it works out for me. I might take my old J30 diff and swap it for 6 bolt one using my todays receipt

Any comment are welcome.

This is what I got for the front:S14 front L+R with 5 lug hubs, picked them of off Egay, for $209.50. I know I could find them cheaper some where else if I have looked, but I need them pronto thats why the price is so gay. Still front spindles and hubs with, Q45 rear hubs and axles and diff (if it all works, I'll probably $hit my self ).

Better price than some ebay 5 lug conversion or Ichiba,(which sell close to $400 bucks for S13) I'm getting all oem parts, so if something brakes I can get it through NAPA or dealership.

Thanks 4 looking,placham.

Here is a link for those interested http://images.google.com/imgre...a%3DGit talks about Q45 VLSD and S13.

[got chub]

looks good i think it should all work. there is a thread on here some where that talks about the J30 and Q45 and what you need to make the VLSD axle and 5 lug work.

i have a full set of Q45 calipers ill let them go for $100+ shipping.

[placham]

Thanks for offer, but I will probably get them from NAPA. I have hookups, lets just say I know many people in this business. My brother works for Toyota Dealership. I will buy all 4 of them front and back, and get S14 front lower ball joint, unless that ball joint are good on that spindle.

You know the link?Looks like I will have to trade one of my axles for core and get 300zx TT axle.

If some one can verify for me about J30, but I looked at 2 different ones and none of them had that bolt in hub.

Will 240sx rear rotors work if I just want to use my old calipers, or do I have to get those goofy ones from Q45?

By the way Q45 has the aluminium rear knuckle where hub mounts to and all other suspension components mount to, I see some people are looking for those from 300zx, but it might be easier to get from Q45 as there is more of them.

got_chub, I really have to thank you for your previous post, thanks for mentioning Q45. Otherwise I probably would not even look at q45, which was parked like 2 cars away from J30 at salvage yard.

[240RB1]

bump i was also wondering if i use the q45 hubs and dust shields like shown above could i use my 5 lug rotors from an s14 or would i need to get the calipers rotors and parking brake stuff from the q45 as well?

[240RB1]

BUMP i have searched other threads regarding this topic and they all seem to be dead ends

[placham]

Yes to your question, but depends what you want to use.

$h!t I totally missed my own thread , sorry bro.

If you use Q45 hubs you will have to get bigger axles from Q45 and 300zxTwinTurbo and Q45 diff. If you want to keep stock axles, get 300zx N/A or 240sx SE '95+ hubs. And with ether Q45 or 300zx TT / n/a hubs, you can use stock calipers, or stock rotors. And Q45 dust shield fits 240sx, but if you use your stock calipers. You will have to trim the extra metal where caliper mounts, because of the parking brake cable mechanism. This is not good if you ever want to upgrade to Z32/Skyline rear 2 piston calipers. Because you will cut away the part that the brake shoes would mount onto the brake shield. Since Z32/Skyline use rotors/disc for normal braking, and drum brakes for parking.

It's been a while but I dont remember the J30 rear setup.

P.S. if you notice the brake shoes would be siting at the height of the hubs, dust shields have indents for shoes to be mounted ant to work in. So a part of that would have to be cut away to mount stock 240sx calipers, since stock rotors are smaller than Q45 or 300zx. Then calipers are more towards the hub, as in Q45 has bigger rotor making caliper sit farther away from hub. But mounting holes are exactly the same.

By the way I skipped the drilling of drive shaft flange, stock 240sx flange mounts onto Q45 diff, its a bolt on affair, just to save someone time.

thanks man so i guess il be goin to the jy and get a diff axles and the backing plate along with hubs seems like il be taking the whole rear end out.

I'll make it easy for you,

If your thinking about going with the Q45 diff, than you'll need these parts.

Q45 diffQ45 driver side axle (only driver side)Both backing plates/dust shieldsE-brake parts, all the parts that have to do with the shoes, hardware, take the e-brake cables too( I'm not sure but I bough Skyline R33 cables. cause 240sx are too short some people get "300zx 2+2" cables)Both Q45 hubs, take the bolts and there is a brake shoe anchor pin on both side take that too.Take also all the bushings, bolts, nuts that hold the diff.Q45 Rotors if in good condition, or you can use 240sx rotors and calipers, but you have to do what I mentioned ealierQ45 Calipers, or you can get the 2piston Skyline/300zx calipers, you'll also will need the pads. I bought my calipers on ebay, I'm upgreading my back brakes. Had to get new dust shield from Nissan, their like $90 each new, because I cut my old ones that I got with the diff.Axle nut is think 36mm, diff uses 19mm/17mm, and I think axle flange bolts are 14mm, So you need your sockets up to 19mm, cause you never know what you'll need. Get breaker bar, ratchet, and some wrenches.

You'll us the Q45 axle on your passanger side.

Now this is the only one of the hardest things, at least it was for me. You'll need to get 300zx Twin Turbo driver side axle, which will go on your driver side.

My diff had ABS sensors on the axle flange, one on each side. I'm not sure if there is any other types, some J30's have it on the pinion (which is by driveshaft)

Any you'll have to change your back cover if it's going into S13, S14 it's a bolt on.

If you see a '95+ 240sx with 5 lug, check that out too, some '95+ 240sx SE had VLSD too, think it was optional.

And I think all Q45's were VLSD, you'll see a sticker on the left side. Like in my pic above.

Think that's it, if you ave any other q's let me know. Aaaaiitttt

[cody180sx]

i got a question what about the 92-94 j30 axles and diff can you use them on a s13 and use the j30 hubs to go to 5 lug then use the j30 brakes for the rear

[240RB1]

i think ima hold off on the q45 5 lug swap, z32tt axles? where the hell would i find them? lol i think ima go with a j30 and grab stuff off of it till it all works out in the rear thanks for all your help though Placham

[placham]

To answer both posts above.

Yes J30 diff will work in S13 or S14, you can use your stock axles (I'm not sure if J30 axles are same length as 240sx, but their same spline count meaning they will work with 240sx hubs).

J30 hubs, I dont think their bolted in like 240sx. Think their pressed in, you might be able to get J30 hub and press it in to 240sx bearing, if that's possible. And that might work. The only hubs that I know that work are 95+ 240sx SE and 300zx Naturally Aspirated model hubs, their direct bolt on to 240sx and you use your stock axles.Q45 and 300zx Twin Turbo hubs are a bolt on but hub spline hole is larger than stock 240sx, that's why you need Q45 and 300zxTT axles.

Think it was from '95 that J30 started to use the same hub/axle pattern that 240sx use. Which is 3 sets of 2 bolts each axles. Older J30 used hub/axle bolt pattern similar to Q45/300zxTT/Skyline, with 5 bolts spaced around the circumference of the hub. But only difference is that J30 uses 5 bolt hub flange and Q45/300zxTT/Skyline use 6 bolt pattern. There are other cars that use this pattern like 180sx I think.

And if some one is doing this just to get 5 lug upgrade or VLSD. What ever you do, you dont have to upgrade your brakes. You can leave them stock if you like.

If you just want LSD, than you can get a aftermarket something like NISMO, CUSCO, KAAZA, TOMEI, which are top quality parts. Which will allow to use stock axles.

I currently have Q45 VLSD with 5-lug hubs and 300zxTT/Q45 axles. My brakes are stock rusty calipers, with drilled rotors from 4 to 5 bolt pattern. This works just like stock.

I just tried to explain the options to others on what you can do. And what I have done, and if you like to do same you can. As long as you dont make same mistakes I made, and just learn from it.

!240RB!- you can get 300zx Twin Turbo axle online or try your local parts store. I paid like $100 for that axle by it self. I know it was pricey, but it was the last piece I was missing.

Sorry to bump this thread, but it seems like the best place to post this question:

What if you had also wanted to upgrade the rear rotors and calipers in addition to the q45 diff? Could you use the z32 rotors and calipers? What about the parking brake then?

From the reading I've done, it seems you would also need:

-z32na ebrake/ splash shield-z32na or s14 5lug hubs (but wtf do you do now if you want to use the q45 stuff?-ebrake cables-brake lines

I guess my question is whether the q45 hubs will work with the z32 ebrake stuff?

***Ahh nm it looks like the OP posted you can use all the q45 stuff and just substitute the z32 calipers. What is the difference in q45 vs z32 rear rotors?

i have a question. I have a j30 diff w/ the 6 bolt pattern on my s13. i want to go 5 lug with the q45 rear hubs.

My question is, since the q45 hubs require the drivers 300ztt and drivers q45 axels, can these axels bolt to my j30 diff? they have the same pattern, but all im worried about is the length of the axels. will they be long enough?

for the fronts im still debating on j30 w/ new retainer clip groove, or s14. i Heard you can use q45 ones too, but modding is required.

thanks

they dont have the same pattern and no it wont bolt up. the q45/z32 TT axles are big 6 bolts and i think j30s are 5 bolt

[ag240]

my j30 diff has the 6 bolt pattern, i made sure of that so i wouldnt have to swap out my stock 6 bolt axels.... im just wondering if the 5 lug from the Q would work with my diff.

arent the q45 and j30 diffs the same width and same distance apart from both the hubs?

Edit: i have the 6 bolt j30 diff as pictured in silviapwr20's FS ad: zerothread/345913

[r3v_v3ng3]

you have a 6 bolt that has 3 group of 2. the q45/z32TT have a 6 bolt that are 1 bolt each

i learnd'd.... damn looks like im going to get a new diff....
