MOVED: Nismo 1.5 LSD axles?

[Xeno]

Ok im new here so im not sure if this topic went here. None the less I searched and couldnt find an answer to my question.

I recently bought a 1.5 nismo LSD from a friend. Well as im installing it the axles dont match to the LSD.

So my question is....

When you buy it new do you get different axles or are the stock ones supposed to match up? If they are supposed to match up then could it be that its actually a 1.5 LSD for a 300ZX NA? If it is then do i need to buy 300ZX axles or are they the same as the 240?

Im not sure what to do here.

When you buy an LSD, yes, the axles are supposed to match. This is because the LSD sits inside of the differential pumpkin, and uses the same output shafts.

If you were given a pumpkin with five bolt output shafts, you either have to get five bolt axles from a J30 or the like and use those OR pull apart the pumpkin, reinstalling the differential into your six bolt hardware. The second option isn't always feasible, so I'd start looking for five bolt axles.

Do you know if the pumpkin bolts up to the 240sx frame?

I just bought the LSD from him. I have another open differential from another 240 I have. Both are 91s. The LSD fits right into the pumpkin just like its supposed to. Only problem is the axles/output shafts dont fit into the LSD.

See what im saying? Thats why I think it might be a 300ZX LSD. Are the output shafts/axles the same or different for a 300ZX?

I mean this ends up being a good thing if it is a 300Z LSD becuase of the lower breakaway of what 40ish lbs of torque vs the 72 for the 240.

Help anyone? Im trying to get this on by next weekend. =\

Maybe we can get a better answer in the 240 Tech forum. Moved!

You dont have to open the diff to remove axel flanges Brad, and if they are all R200's I dont see what swapping cases would do...

It sounds like you have a diff already in the pumpkin, with axel flanges in place (axel flange being the part that sticks into the diff, and the axels bolt to) but the axel flanges are 5 bolt and your axels are 6 bolt?

If so you should only need a set of 5 bolt axels....I think like he said the J30 came with the ones you need but searching for 5 bolt axels(or searching about VLSD, I think some of them are 5 bolt too?) should be able to tell you where to find them.

Maybe I'm not understanding the issue.

Most of the time, when people with one post pop into 240sx Gen chat with a differential question they don't understand the difference between the pumpkin and the differential assembly. That's where discussion of the case came from. Sorry to confuse.

I was/am still a little confused by his situation. It's not a matter of outputs/axle flanges not matching up (5 bolts vs 6) but that the 240sx flanges aren't fitting into the differential.

Also, it's important to note that most LSD manufacturers (those with any credibility at all) produce TWO types of aftermarket differentials for Nissans - one for replacing OPEN diffs and one for replacing worn or otherwise undesireable VLSD assemblies. This is because Nissan did not manufacture the output shafts to be interchangeable. Open diff outputs only fit on open diffs and aftermarket units designed to replace them. The same holds for VLSD outputs.

Point being, if the diff that he has is designed for or otherwise came out of an N/A 300ZX, he needs the corresponding outputs. Those may or may not be the same as the J30 five bolt outputs, but I dont' know. Assuming all other thing are equal, he could get J30 outputs and axles and be okay, OR get a set of 6 bolt outputs from a 240sx, right?

Correct, this is about the flanges not fitting directly into the LSD. The flanges used on the 240 open differential don't match up.

Im sorry I wasn't able to make that clearer. I didn't really know the exact term for each part. Although I may be a noob on the forum, im not a noob when it comes to working on a 240. just dont always remember the correct terms. :P

None the less from more researching it seems like a plug and play deal now. Only 1 thing is certain on the LSD, its a nismo 1.5. Other than that it could be a VLSD replacement, or a 300ZX N/A LSD. So pretty much I guess i have to figure out which flanges are going to match up.

I didn't know the flanges for each one would be different. I was hoping they would all be the same or there would only be one thats different. Ill post up what flanges I had to use to solve my issue for later reference in case anyone runs into the same thing.

Ok so I found out I wasn't sold a Nismo 1.5 LSD. But rather a 300ZX VLSD.

So im pretty dissappointed in that. None the less, I just need to find J30 output flanges.

damn that sucks ALOT,Quite a bit of difference between a clutch type and and a viscous

I was going to say, there is no Nismo 1.5 way for the 240

[ath~muncher]

Yes there is a Nismo 1.5 for the 240 since they are all R200 diff's they can be for any car using the R200. I have both a Nismo 1.5 in 1 of my 240's and a Z32 N/A diff in the other.

Make sure that the Z32 diff you have is from a non-turbo so it keeps the same ratio as the 240's. If its not you may want to consider selling it.

[Xeno]

Yah i know. Im trying to get a hold of my friend that sold it to me. Im pretty damn upset that he tried to rip me off like that. REally I just want to know that exactly. Whether or not its a non-turbo or NA VLSD.

So I might be selling that VLSD soon. I dont have the money right now to buy the flanges. Im trying to see whats up.
