Hello,
I have a faily new patrol GU with a 5 inch lift and am running 35's and have just been away for the weekend on a dusty bumpy track, this morning after empting and cleaning the car on the way to work i have a creaching noise in the rear of the patrol when i go in or out of a drive ways or over a big pumps, this is the only time i can notice it.
it does not sound like it is coming from outside of the car.
Has anyone else had a noise like this?
Does anyone know how to fix the noise or know what it could be?
Thanks Heaps

Dunno why it would have just started, but suggest you
check if the 35's are rubbing on the inside of the rear mudguard. If you have standard Nissan wheels, this can be a problem when they are at full
suspension compression. Mate of
mine had the same thing with his 265/75's MT/Rs and a 2" lift.
My ROH Sunraysias have a 20mm wider offset than the standard wheels and provide more scope for this sort of problem.
If there's no
sign on the upper inside of the guard of any scraping, then I'm sorry, but I have no idea what it could be.
Cheers
Roachie

Who did your lift? Did it include a body lift or just springs? Make sure that the blocks they used for the body lift (if one was done) are the same size as the sections of body they are meant to support - especially at the rear. I had
mine done and they used small blocks that didn't spread the weight on the body-side mounts
well enough. They split and cracked the body, and it needed re-welding around the edges of the new blocks after just a few hundred km's.
Failing that, you may just have a lot of abrasive dust left in the rear trailing arm bushes - or others in the vicinity....

Should have mentioned properly - the cracked body mounts were making a similar "creaking" sound to what you describe.
(gee I wish I could EDIT a post I put up after I hit the button...)

Try spraying a pile of WD40 at the top and bottom spring mounts - dust and all. See if this changes the noise. Keep spraying bushes until you find the one that makes the noise.
Do you have polyurethane spring pucks (spacers) installed at all - or are you running metal to metal?
As far as the body goes, you can see the rear mounts through
the gap between the rear of the body and the chassis - if it's been lifted. The cracks in
mine around the body mount (the part of the body that sits on the body lift spacer) were as obvious as bog's dalls. You couldn't miss them.

Oh yeah - I forgeot to mention that if you want a silent 4WD that doesn't squeak at all - don't buy a Nissan Patrol.
If you want a car that sqeaks a little but will hang together through thick and thin - then DO buy a Patrol.
Mine has rattles and squeaks (which I hated but got used to) but NEVER has it let me down.......... ever.

Hi Brent,
Its a guessing game when it comes to this kind of thing mate. But from what you wrote i can only think it was caused by your weekend away. Personally I'd be checking everything at the rear of the GU, could even be a piece of steel or a branch stick stuck in an arm somewhere thats rubbing on ur wheel or surrounding area. Possibly something coming loose after bottoming out while offroad. Also from what i read, in my opinion, Im pretty sure its tyre related due to the size your running. Mudflaps, inner guard fittings or something of that nature sounds to be the cause. Also
check your rear calipers, sometimes the clips that hold your pads in can snap and screech as they rub on the rotor, this happened to me a while ago.
This is what i would be looking for, but not hearing the noise is difficult to tell.
Do a general
check of everything in the rear end, look for scuffing marks and the likes.
Hope its a simple fix.
Angelo.

Thanks Angelo,
I have had a good look and i can not find any signs of rubbing, i have not checked the calipers yet.
Are there people out there that just find these type rattles / noises? because most mechanics dont event want to know about it.
