I finally purchased myself a GQ. Its a 1991 DX 4.2D with 270000 km. I paid $9500 from a dealer which included the Warn 8000lb winch and bar. I'm very happy with the way it drives but it sounds like it has a crack at the base of the firewall on the drivers side - (one of the cracks I was warned to look out for) It clunks when cornering and over bumps and I can actually feel something through my feet when it makes the clunking sound. (It didnt do this on either of my test drives) The thing is, I cant actually see a crack. I've pulled out the floor covering and looked underneath but cant see anything. I was a expecting to see a huge crack based on the noises it makes.
Has anyone else experienced this with their GQ's and is it easy to repair? or should I just put up with it. I have to say I find it annoying if nothing else.

They all do it, and if you cant see the crack, its where floor and firewall meet.. Pour some water on there, not much, and see if it leaks through.

Something else to check - your body mount rubbers they wear out, and when you turn, or come in a driveway, they move, CLUNK... Around $450 a set for the whole car (LWB).

They also get a kink in the floor pan, which you CANT fix...

You can take it to Nissan they will hit it with a hammer, adn do nothing.

Depends on what you find dont it and how tolerant you are ;)

I've had various clunks and knocking noises in my 89 GQ. For some reason, they were worse/revealed themselves after trips to the Cape last year, and along the Fink this year. Dunno why, its only 14 years old and got 325,000 kms on it - just run in!

Any way, there were three sources of these noises.
1. Body mounts replaced - the front ones (four of them I think) solved the post Cape Noises
2. Front trailing arms bushes replaced post Fink - using ones that had a castor angle adjustment from OME, that compensated for the suspension lift.
3. The ball joints connecting the sway bars, both front and rear, had given up the ghost. The rear one on the right was the worst offender, and for some reason sounded like it was coming from the front right through transferred noise. I now have additional wheel travel, now that I have no roll bars (may refit front one, back one more complicated as it had the quick release mechanism, now stuffed)

All the above fixed, and feels like a new truck again, ready for more offroad adverntures.

I've given the truck much curry on rough roads, and all those noises sounded like cracked chassis/body etc. But the "old" girl is as sound as a bell.

Keep looking.

I had the same clunks beneath my feet. It was the body rubbers moving around because they were worn. I noticed it more when braking or driving up the driveway . . . I guess when the chassis is flexing. Mine is roughly the same vintage and has had a pretty hard life. Fixedthe rubbers (they were all stuffed!), new radius arm bushes and it's all good.

Thanks for the replies - very helpful. I think I will take a close look at the body mount rubbers..........
