Where is the clunking noise coming from? Is it a diesel or petrol model, and when was the last service.

Gunnie, I would suggest taking the vehicle to a reputable 4WD mechanic in your area (good place to find them is on this forum), and getting a full service done. Might cost a little more, but reliabilty counts when off road. ( a broken fan belt can stuff your day)

Where do you live, then maybe some of the forum members can advise a good grease monkey?

Hi Gunnie,

Yeah, GQ's do have a lot of little noises, but they are usually nothing to worry about. Is you vehicle lifted at all?? If it is, the exagerated steering/suspension geometry can cause a few clunks. Check all your bushes for wear, and all bolts for tension.

Have a look at Trucksters GQ site. It could help.

This has come up on the Nissan list from time-to-time.
The body mounts are the usual reason given for clunks in the GQ.
Truckster may be better to confirm this, but the holes where the bolts go thru can become elongated or there may be cracks in the body at these points.

anyway something to check
good luck

I had similar sounding problem and it turned out to be excess 'slop' in the amount of freeplay in the driveshaft. To check climb under vehicle (handbrake on, motor off :-)) grab the drive shaft and rotate back and forth. Evidently 'some' freeplay is ok, excess will cause 'clunk' especially noticeable when you 'pump' (accelerate de-accelerate) the accelerator whilst driving.
I havent had it fixed yet as the mechanic said it isnt excessive, but I will fix prior to going North next June.

Some cars have a rubber bush in the universal jt, which can deteriorate, or it might be a universal joint itself. I hope its something cheap.

The A/C can be pretty noisy when it kicks in. Does it clunk with the A/C off.

Hello Gunnie,

I have got a '92 petrol GQ and have had all the same problems as most other GQ owners. First of all has it had a body lift and if so were all the body mounts replaced as they will cause a knocking noise at around this age, 10 mounts at $230, fitting is easy, one side at a time. The passenger footwell is normally the worst.
Both my engine mounts were broken which was causing a loud knock, $60 each and a bit of time. I also replaced my gearbox mounts to be safe as my car really only gets used offroad now and normally fairly hard, $80 each genuine nissan and quite easy to fit.
Make sure that the exhaust is firmly in place as I found that my heat gaurds were hanging loose.
Funnily enough after all that I still have a knock so if you find anything else please let me know.

Hope this helps,
Mark.
