Thud Noise From Rear When Shifting!

[GBLOCK]

Hi guys, have had my '89 R32 GTS-4 for about a month and abit now, and a very noticeable 'thud' noise has occured everytime I shift gears. If I shift very gentley the noise is reduced but it is consistently there even at very slow speeds. I've ruled out something being loose in the boot (as the sound resembles a loose object moving around the rear of the vehicle) and being a total noob at cars, have no idea on what the problem could be. If anyone could help it would be much appreciated

Sounds like your bushes in the rear susp may be worn out.....

Awesome, I'm getting the bushes on the control arms replaced some time this/next week through my dealer warranty, so I'll have these checked out along with it. See how that goes about fixing the problem. Thanks mate. Other suggestions to the cause of the problem would be greatly appreciated

could be the (a) diff is buggered.. They tent to clunk when power is applied and then released.

Is it possible someone changed the diff centre to something a bit tougher than the stocker? if it's mechanical it'll do that.

Not likely mate, the car is completely stock throughout.

Predator, what can cause the diff to sh*t itself? I've been reasonably gentle when driving it. Would it's age and general wear and use cause such damage?

Age, wear and tear.. and you really don't know how it's been treated in the past in its 12+ year history.

But get the bushes replaced first and see if that makes a difference - at least you have eliminated one thing.. I've had previous cars with bushes so bad the diff flops around.

Awesome, thanks for the advice mate. It'd be less costly than replacing a diff I assume? You reckon it would be worth replacing the bushes all the way around?

not the dif!

its the diff bushes. (above the hicas rack)

mine are shagged. oil soaked and yes a nice deep "thud" when backing off whilst still in gear.....
