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

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, I hate noises/rattles/creaks. Could it be the rear door rubbing on its stop ?

when you mean rubbing on its stop, is this the plastic think on the main frame, how do i adjust this?

Thanks

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.

Try getting right under the vehicle, get one or 2 persons with substantial weight to stand on the rear of the vehicle and bounce up and down - may help to be under the car when it squeaks to help pinpoint the problem.

Find somewhere that stretches the suspension and drive over this area slowly with observers watching and listening closely.
Oh! and you get to learn to live with the IDENTIFIED noises then it's the unidentified ones that annoy.
I used to have a handle on life, but it broke.

gday mate

i had the same thing in my maverick with 4 inch lift after i went on some serious tracks one weekend. took it to the mechanic who does everything for me and told him what was happening, like you only happened on driveways etc, he said its the springs turning in the mounts. i ignored it for a few weeks and then it stopped, especially when i went to carlovers and washed the crap out of the car.

just a suggestion mate

cheers

G'day Brent,

Sorry mate but when I read your response I couldn't help myself. Most of the mechanics I have dealt with are in a trance like state and don't really care about what your asking of them but they become more alert when they are working out the bill though.

Kind regards

brent, im in queensland mate. he is in north brisbane and has looked after me ok since i moved here. main reason for using him is because he is just round the corner from work and it is convenient for him to be able to pick the car up whilest i am working. beatit, this blokes ok but i know what u mean about trance like state, so i always take their advice with a pinch of salt. point was, washed the car thoroughly and creaking stopped (softened alot) :)

cheers fellas

Hi Brent, My GU (now 2 years old) has done this since new when I go out my drive or on some other big angle whilst turning and I am pretty sure it has always been the rear doors.

Come to think of it I am not too sure but think so, really only when doing reasonable angle stuff therefore I am not too fussed.

My GQ always had a similiar noise in the rear door locks after a trip away and basically I just cleaned all the dust from around the door seals and the locks, the main area that i used to concentrait on was the plastic locating wedge as this seamed to be the main culpret, a spary of the old magic lubricate in this area seemed to do the trick.
So far my new GUIV has not done it (only four weeks old) but then I have only had one trip away so far.

Good Luck on you search

Either the barn doors or if outside and I'm assuming you have castor correction and adjustable panhard rods, it may be the extension links to your swaybars loosened off after a good workout. Get under the vehicle with a few spanners and tighten everything. Has happened twice to me now, once with the 3 inch and once with the 4 inch...just settling in.

Cheers.

Check the new shocks. I'm guessing they're oversize. If so, you have to remove a section of plate attached to axle diff housing close to the shock bolt, so that when the diff housing rotates horizontally (as when going over a gutter/dip etc) this bit of plate does not contact the oversized shock.
Remove with angle grinder/cutter. Just a thought.
