Hi, i have just bought a GQ shorty with 2inch lift (guy said lift was 2.5inch...) and when braking, turning or hitting bump you can here a 2 clunks under foot pan in cab. It sounds like panhards but im not sure.

Any ideas would be great thanks :) (i've tryed bouncing cab to get the noise but carnt seem to)

Body mounts, or can be the coil moving on the diff mount (which I have found on my GU and GQ shoties, rubber under the coil fixed it)

jack the front off the ground and get under it.

I think is is more likely to be a drag link of panard.

Could even be the sway bar rubbers or link at that end at the front.

Given it happens ALL the time it is less likely to be the coil moving i would think. The are a heap of suspension components attached to the car around there.

Get under it and give is all a wobble.

It could even be a Seat mount if you cant make it happen when you are jumping on the cab.

If it was a shock rubber it would happen all the time and would drive you nuts.

Drag Link bush in front of the front diff,
Panard in front of the front diff,
Tie Rod behind the diff
Stabiliser bar link right under the driver floor.

The last thing to check would be the Radius Arm Bushes may be shot and would give you a clunk in those circumstances.

Thanks for replys,
i think i may have found the noise my friend said it's the floor pan a patrol thing. The metal on pan has expand and pops in and out. There may be another noise but least i've found 1. We tryed pulling on everything suspension related and couldnt find anything

the seam between the floor pan and fire wall cracks and causes this sort of thing. i found the passenger side cracked first, repaired it, and 4 years later the drivers side did the same thing,

i just had it welded and braced,

mine cracked on pasanger side and i stitch welded it inside and out then seam sealed it up, driver side is still ok, suspect body mounts are shagged but dont have a spare 500 bucks for new ones

Same noise I had in a GQ wagon. It was the body mounts. Didn't bother replacing just put another washer on and re-tightened. All good and didn't happen again right up till I sold it many years latter.

where did you put the washer?

On top of the body mount, my mounts had compressed and the nut had bottomed out on the thread. Hence the noise as the body moved around from the rubbers being marginally loose. Though not loose enough to be able to move by hand. so I used thick mudguard washers (large ouside dia) and drilled to suit the bolt. In fact I think from memory I used shocky washers and just drilled them out to suit. Took the noise away for good. I'd tried changing just about every bush in the front end plus the rubber between the coils and tower. This was the last resort and worked.
