ok need help with Q45 swap from someone who has done it

[6.0 turbo turd]

I have a 95 240 I have done the 5 lug swap from 300zx all around. I have a 97 Q-45 diff in the car did the Q-45 driver axle on the pass side fit like a glove. I read that you need to use the drive TT300zx axle. I keep reading to use the driver side because it's "SHORTER" but the driver side axle is 23" 7/16 and the passenger side is 22" 5/8 and on my ruler the pass side is shorter. I went with the driver side axle and it does not fit under the car it's too long. What a surprise. So before i just keep throwing $$$ at it i wanna know what is really needed to do the swap and move on.

thanks for your time.

Any of the passenger side axles will not fit period. You do have it correct for the passenger side. The driver side you will need a 92-94 j30 driver side axle..... That'd the only thing that will fit on that side. If you had a 90-96 q45 diff then yes the z32 tt or the r32 skyline axle would fit byte that is because that diff has 6 bolt axles, not five like yours.

92-94 J30 driver side axle will bolt right in? that years J30 axles are % bolt or do i have to do some swapping s***?

[compactfean]

Direct bolt in as long as your q45 diff has the 5 bolt output shafts. I ran into this problem when a thought I had j30 axles when I actually had 300zx axles. (a real pita to figure that one out considering the only difference between the 2 is length)

[compactfean]

You said you have the 300zx five lug conversion all the way around..... I thought the fronts didn't fit?

I did these the rear has the same size/ spline count as the 300zx as well as lug pattern.

just pressed the stock 4 lug s*** out and pressed this stuff in was very easy and worked well.

[compactfean]

Oh, ok. Yeah the oem front hubs do not work but rears do. I thought you were talking about the actual stock hubs off of a 300zx and I know the fronts were a no go.

Great I can't just go to an auto parts store and order a J30 axle no one can get them this car is getting to be such a pain in the a**. About to just sell this one and pick a shell that I can still get parts for!!!!

[compactfean]

Check for a dismantler they will pull it for you and everything. You think that's bad try sourcing the 300zx tt driver axle like I did..... I had to even search other countries! when your doing piece it together projects you have to be patient and keep searching...... That's half the fun is the hunt. Lol a lot of people don't realize these cars are becoming classics.

I'm 35 it's not fun to spend weeks hunting for a part fun for me is driving the car. I wanna make passes at the track and drive it around now walk on glass worried if i break any thing the car will be down for months because simple parts are not available . So if it is going to be this hard i'll put it back together sell it running with the brake up grade with the 5 lug and the Q-45 swap done then build a car i like the way it looks and parts are available. I'm not using the motor or trans out of any of these cars. I picked this SHELL based on looks there is other shells i can pick that i can get parts for that won't cost me an arm and a leg for and wont take months to find.
I'm sure these axles won't last long making passes on them so I need to be able to get them pretty easy or it's a wash for me.

I found a 94 J30 axle it's not 5 bolt so that won't fit so what year axle really fit's a 97-01 Q45 swap into a 95 S-14 ???????
I need to know exactly what year and what car because every time some tells me this will fit i get it and it does not work so whats the real story?????

[compactfean]

Hate to burst your bubble, but the axles that were for this setup can only handle about 400hp launches. The setup that you should have gone with was the 90-96 q45 with the 6 bolt axles can handle 800+ hp. But then again, would need the tt axle (witch took me 4 months to find) but if you really want bad a** stuff right now, just spend the money on the mazworx axles and you will be set. You want quality you rather have to pay for it or put it together yourself.

[compactfean]

As far as the axle you just found, its a late model j30. You need an early model 94 because that is the year they switched axles to the 6 bolt (in sets of 2) that'd the real story. Maybe you should drive a domestic.

[6.0 turbo turd]

what is the diff between the tt 300zx driver axle and the n/a axle? there are same splines and same length so whats the diff?

[6.0 turbo turd]

Yeah i should drive a domestic because i don't know the ins and outs of a car company that changes parts every 6 months on every car.
I have a 95 RX-7 with same set up i'm doing in the 240 and i just go get parts and they only made the car 3 years, and is much more of a rare car. this is why i'm asking the questions i am about the car. I've been fed bull s*** over and over last 2 months i've had the car.

[compactfean]

The tt axle is not the same as the na. It is shorter, 32 spline, and 6 bolt. If you went with the earlier q45 you would have had to switch hubs as well. And 95 rx 7...... Isn't that built by ford? Lol. I, guarantee you im not feeding you any bs..... This is all first hand experience. I've installed q45, j30, 300zx and skyline diffs into 240sx's so no need to doubt me.

Im in need of help. I went to PAP and got the rear end out of a Q45. The diff was a direct bolt in for my 1995 subframe. I ran into trouble when I decided to change the bearings on the q45 rear hubs. I ordered 300zx TT rear bearings and the center is too small. Im not 100% the year of the Q45 the parts came from, but it has 32 splines in the spindles like a 300zx tt. What I have read they should be the same. Has any one had this issue?

Does any one have info on the q45 bearings out of a 2002+ q45?
