Howdy People,

Can anyone help me with finding the source of this banging noise. It doesnt happen all the time, just every so often...the vehicle makes this banging noise that sound like it is coming from under the drivers seat or in the middle between the front seats. Its been up on a hoist, we hav prodded and poked every thing that we can find under there....and still have no idea what causes it.
When its raining and the roads are wet...it seems to get worse....but like I say....the banging noise isnt there all the time..I can go ages without hearing it...then all of a sudden it will bang away...then it will bugger off again.

I get some strange creaking and squeaking noises out from under her at different times...mostly when I have been down dirt roads. If I hose her off underneath...squeaking goes away...I thpought it might be rubbers or something like that getting dust between them.

cheers
Tazz

I had a patrol a few years ago which was making a noise like you said, sounds like it comes from under the seat or floor got real loud somtimes. It was the front shock absorber bottom rubbers , when they got wet the bolt/stud in the middle used to bang side to side , made a lot of noise, was ok when dry. I fitted some new bushes and never heard it again. Hope this helps

it very well could be worn body mount rubbers, sounds like a "clunck" when cornering etc, for a lwb gq roughly $400 to replace (parts only), im sure once others read ur post they will agree with me,

just sounds quite common

The knocking noise under my Patrol was a loose bolt
on a stabalizer bar. Get someone to jump up and down on the
bumper, get under and you should fined the source.

I rekon a whole packet of welding rods were used whilst repairing my cracked gq.....it was cracked from one side of the sill to the other side...right across the gearbox tunnel also/.....
but a welded gq is a tough truck.. hehehe..___________________________________

Hey Truckster,
Im thinking of doing the body rubber thing too....but reading up on things in the past, I am wondering if the job is made any harder if I have the rear storage _Affordable_Storage_Drawers.aspx in the back, do they interfear with the replacment in any way, or is it all done from under the car.I love it when you talk DIRTY !

Coke, there are 2 bolts that you need to get to from the top, they are right at the back, about 2-3inches from the back, you will see under the carpet 2 rubber grommits..

we did mine with the red desert unit still in there No problems...
