Gtr Diff Making Car Unsettled Over Certain Bumps

[JonesyGTR]

G'Day guys,

My R32 GTR has a worn rear diff that is still quite drivable and doesn't really play up unless it's under heavy load on a tight-ish left hand turn.

However, I have noticed lately that if I go over a bump the car becomes really unsettled almost starts pulling very hard to the RIGHT. Only seems to happen if the car hits something on the LEFT hand side (pothole, dip in road etc). In the wet, this makes my car very dangerous as you could imagine.

I have subframe bushes (pineapples) fitted. Don't know if that makes a difference at all. Hoping for some insight here guys on if anyone has had a similar issue or can confirm it is related to the diff.

I am going to get another diff, just want to make sure thats the only prob and that I don't need to change other things whilst I am at it!

Appreciate the help!

Anyone? Just after some input guys before I change the diff only to find out there is also something else.

Handling problems are usually related to suspension. Check the suspension by giving it the "bounce" test. Try swapping components from L->R, R->L, see if the problem moves.

Yeah, as blind elk said check your rear shocks. I had a similar problem when I bought my silvia where the rear would "steer" over bumps. It turned out that one of my shocks was completely knackered and not providing any spring control while the other was OK.

As usual the first job is to check the installation, no loose bolts, nuts etc.

Next is worn components, shocks, bushes etc, make sure everything is working as it should

Then it's wheel alignment time, make sure the camber and toe are where they should be.

Then and only then if the problem still exists should you look to the diff as the solution.
