Diy:diff Shimming For R33 Gtst

[bubba]

Bubba, has it ever single pegged since shimmed? Also does it still chirp around tight corners?

Nope, no single pegging and it doesn't chirp around tight corners anymore. The only time I can feel it bind up slightly is full lock, reversing out of a parking space.

Even at its' worst (when it was nice and fresh), it was still nothing like trying to park the 32 with a button clutch and 2-way

Ive rounded off the righthand side nut in this picture. about to pour petrol over my car and throw a match on it..

Tried smashing on another socket but its so hard to hammer it in the position its in.

Soaked the crap out of it in wd40

Any help would be appreciated.

How do you round off a nut when your using the right size socket? are you sure its not the ratchet slipping? try using a breaker bar and see if it still slips.

Only other thing i can think of, assuming you havnt round it off too badly, buy an impact single hex socket, in the mean time just keep soaking it in WD40 every 30 minutes or so, by the time you get a socket tomorrow it may have made a difference.

not sure, the other one came off relatively easy. its rounded quite badly by the looks of it. just got the oxy torch on it, if i have to i'll replace the bush in there.

i doubt theres a more difficult place to round off a nut haha. oh well, extra points!!

I cant even figure out what you have taken a picture of?

The back of the diff where the cradle bolts on

Its the 2 studs that come from the diff housing (same side where the drain plug is) it pokes through a beam thats attached to the cross member.

Managed to get everything sorted.. Thanks for the tutorial, and to others who have put their findings and suggestions in.

mines working well for what its intended for, worn in with in a week and is nice and locked.

now has anyone set the backlash before and do they have part numbers for the backlash shims on the crown wheel?

now my diff does get some hard use now and again and it's started to chirp the rear wheels while driving normaly, straight with good tread tyres etc would this have anything to do with using castrol manual vmx 80 or i figure its also that i have to get backlash set ( as there is some play more then before it was shimmed )?

thanks

I will be considering doing this as my car really does not like giving me two wheels anymore. Straight line I am ice skating everywhere and it is definitely one wheel spinning... I tried to spin the tires(not for show but just to test the diff) and it is definitely only using one wheel when its spinning.. I don't care for burnouts but if I could tighten up the straight line action, that would be great but from reading here it seems this has more effect when the car is sliding/turning/coming out of turns etc and straight line its still a one wheel... Nissan should have made this diff tighter..

Just performing this on my diff and I need 2 new axle seals... Any ideas where i can get them???

seems the appropriate thread to ask, anyone removed the pinion out of their diffs??

im in the process of removing mine, have removed the large nut (bloody tight) and splined flange off, the centres already out

tapped the pinion end with hammer lightly with the nut on it, but no movement

suggestions?

It's not a proper LSD, just a highly preloaded VLSD, so it basically won't lock up much harder as you accelerate and you are relying upon the preload to do all the locking for you.

[LANDSCRIBBLE]

Diff is still tight as a... I think its worn the shims in ever so slightly, but still likes to rattle and chirp on tight corners. Better than that single pegger shit.

[malkie]

allright dudes,iv just finished with a mate his r33 lsd using 1.2 shims its allright but going more after the weekend,tryed getting 1.49s but nissan can only order them in from japland so i settled with 4- 0.8 and 4- 1.2 so im sure we'll get it good and tight soon,had a wee run there but not to happy but we'll give it a weekend first and c, ill keep yous posted

So for a mostly street driven car doing the occasional skid pan day, is this a worthy mod?

Is there much risk of the diff failing on a long interstate drive by adding this pre load? Or chewing out tyres early
