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 :D

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?

    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻   
    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
