R32 Gtr Diff.... "duk-duk" At Turns With Low Mph..

[GreeceS13]

I bought one r32 gtr rear diff and I don't know if it is stock or not.

I try to turn one wheel and my friend to hang the other wheel and it is imposible!!!!

I try to put off the wheel and I put a big screwdriver in the brakedisc to stop at the caliper... I try with first gear to run a little... ok it turns only the other wheel but after 1min the screwdriver gone...

My problem is that in every turn with first gear (low mph) the car do a bad noise and feel! A "duk-duk-duk-duk" and a feel that the car at the rear have a bigggg problem!!

Anyone who can help me?

My car is silvia!

lolwut? you put a screwdriver in the wheel and tried to drive?

It's probably just an aftermarket mechanical diff.

Is it the "inside" wheel or the "outside" wheel? Sounds like a "locker".

Lol, I do not recommend you ever put a screw driver there to see if it will "unlock" the diff.

I have a standard R33 GTR diff and it locks as above, both wheels turn at once not one at a time.

I had my diff loosened due to this, my car used to do it and it still does a little, the housing of my diff was machined to loosen the preload to prevent this, it used to make a loud clunking sound on tight corners.

You may have a diff that someone has shimmed tighter so it locks more, an aftermarket centre in your diff, OR someone welded the diff inside (as per previous posts).

A diff specialist can probably help you reduce the preload a little to prevent the bad noise, the diff probably has a lot of preload, which is fine for a track, not so good on the street. OR someone has welded it...
