r32 differential crush sleeve

[Old_Zeuski]

I have an r32 gtst with a pinion seal that is beginning to leak. It has a stock diff and I believe that means it is an r200 short nose. However I am hesitant on replacing the seal and leaving the original crush sleeve, I don’t want to do this twice. Unfortunately I can only find crush sleeves labeled as a GTR part, not a GTST. 
 

so, is the factory diff an r200 just like the GTR, or even an s13? Do they share the same crush sleeve? The same seals? Same torque specs? I know the internals are different, and the output shafts are 3x2 instead of 5x1. 
 

I have no interest in swapping diffs. Trying my best to make the stock stuff work

Now I am reading that Nissan does not use a crush sleeve and it is in fact a solid spacer. If this is true then I will not need to replace anything if I am only doing the pinion seal?

R32 GTSt is definitely 5x1, not 3x2. #x2 n NA Skylines and S chassis cars.

You could have a diff from just about anything/where if you have 3x2.

I can tell you with absolute confidence that the R32 diff uses a crush washer/tube.

yeah I have 5x1 cups. So is the crush sleeve the same one used in the GTR’s r200 diff?

GTRs use the same 4.11 CW&P set in the same basic case, so it is very likely that the pinion shaft crush tube is the same part, but I couldn't promise you. They're only like $40 or something, so just get one.

But now I look at your original post.....you're doing work on the original viscous diff? You really must not car about how the car drives. They are a piece of shit. Prime opportunity to put a proper centre in it, while you have it open and apart.

Quite the contrary. I enjoy how the car runs the way it was built to run and I don’t have any interest in ruining that with some noisy aftermarket ring and pinion. It still locks up and hasn’t given me a bit of trouble. Seems like staying stock is the best way to keep these cars on the road. 
 

Thankyou for the info on the crush sleeve. I will get one and report back after I give it a shot.

Look up S15 helical.

And it's not the R&P gears that make noise, or LSD action.

Heh. I come back to this thread to recant my statement that R32 GTSt (and other S & R chassis diffs) run a crush spacer behind the pinion bearing.

Definitely a solid spacer/washer. About 3-4mm thick.
