Hi guys,

My Elite V6 has all of a sudden started making a very loud CREAKING on off, noise when under breaking. You actually only have to dab the pedal and as soon as it starts to bite its makes the noise.

It goes creak>no noise>creak>no noise>creak>no noise, until the car stops.

It doesnt do it when in reverse, only going forward, and does it at any speed. Braking doesnt seem to have been affected at all. Straight away you assume brakes as it only happens when braking, but I dont think it is anything to do with the brakes.

Quite un-nerving to be honest.

Ive had the calipers off tonight but everything seems ok.

It almost sounds like a dry type creaking noise. Its loud. Could it possibly be suspension? Dry ball joints?

Im hoping someone has experienced this before.

Anyone any ideas/input?

Thanks

Yuk, sounds horrid, is the noise in time with road speed?  i.e. In time with each wheel rotation gradually slowing as the car pulls up?

Is there any tyre ware on the inside/inboard edge?
What's the distance between shock body and tyre edge?
Is pad ware even both sides of each calliper?
Do the calliper sliders move freely?


Or is it more random with no rhythm? Possibly in time with suspension movement? Guessing not to this one.

Might sound a silly question .. but where do you think the noise is coming from ??  It wouldn't be back seat area by any chance ??

Reason for asking is there was a "tech bulletin" regarding chassis noise from the rear seat area, the fix involves a small bit of "metal bending"

Hello,

Yes, it has a rythmn, as to when the car slows down.

As you mention inner wear, I shouldnt really say this, but the inside edge of the front OSF (drivers front) has bad wear, the metal wire strands are showing through. I was pretty shocked when I saw this as yes its on the bars, ready for tyres, but wasnt expecting this sort of deterioration on the inner edge.

Could this be my problem?

Ill check the inner wear between the sock and tyre.

I checked the pads for trapped debris, and also checked the sliders when calipers were off and they move sweet. Pad wear is even, checked this, only had them on 4 weeks or so.

Love knowledge on forums!!!

Cheers

Yeah its defo coming from the front for sure. But so hard to pinpoint.

chrisgixer youre a legend. Just been out and checked the inner edge and yes, its soooo close to the shocker. Will presume this is my problem. New tyres monday

Bloody he'll, yes it's definitely a problem. 2 possible causes IMO.

1, wishbone bushes are shot allowing the geometry of the front wheel or wheels to slip out of position.
2, the camber is set incorrectly/too aggressively on that wheel. Has there been any work done on that side? New shock or spring perhaps? If so then it sounds like the camber was not set correctly after the work was done.

This needs correcting, urgently. Where are you in the world roughly? Fill in your profile location so we can guide you further. Also see wheels in motion web site.

Obviously your at risk of a blowout with the car in that condition.

No not yet, put the spare on that side now if need be, then get the problem diagnosed properly. Correct the fault, THEN fit new tyres.

[sjc]

Have you checked the other side?

[Ghost]

I also have a creaking noise, sometimes when I brake hard but not all the time. and when I go round a tight left hand corner. I believe it is the bearings at the top of the struts ran dry.
I sprayed a bit wd40 inside at the top of the strut and the noise seemed to have gone for a few days till it rained again.
you might have a similar problem.

( was just a thought. )

[feeutfo]

It's entirely possible the noise is not caused by the tyre wear problems, but the fault needs addressing regardless. And yes check both sides.

Note, always change suspension parts in pairs, wishbones included.

[Lancave]

Right, its definately the camber. The NSF is ok clearance wise.

I can get both hands to meet eaisly, when put in from either side from behind the wheel, NSF. Theres plenty of clearance between tyre on strut.

Driver side, hardly any clearance, talking afinger width to meet. I dont think the tyre is rubbing on the strut when moving but obviously cant clarify this, just under heavy braking.

Visually there does look to be a lot of tow in on both sides of the fronts when looking head on. Seems to be quite a bit of negative camber.

Regardless though, its dangerous and will get this sorted on monday. It needs x2 new front tyres so will just get it done when these are being done.

Thanks for your input been great!

Im in Preston, Lancs.

Ive had no work on suspension done in 8months or so of ownership.

Having had a good look, your point 2 seems to be the issue as the other side is nowhere near as much negative camber.

However Im not discounting point 1.
