Creaky joint

Folks,

My S has recently started to make an annoying creaking noise at the rear - on the driver side. I ran this by my mechanic and he diagnosed this to be caused by dry/old rubber at the joint which is more annoyance to the driver than damaging to the vehicle. Silicone spray or WD40 isn't helping lube (at least - not sure, if there is a particular section where this needs to be sprayed at) - just keep trying here.

He mentioned that to permanently get rid of this creaking noise, a new part needs to be landed (approx $400) and he didn't recommend that I do it yet. I do have a few miles on this car (106,xxx) :drive:

Just wondering if anyone else has had this issue before and if so how did you get rid of it. I hate driving thru the parking lots in a creaking Porsche :soapbox:

I'm attaching a photo with the area, colorized, where I believe the noise is originating from....Does this help?

Try injecting a little gear lube into the rubber boot of the lower bearing. Use a large syringe. You can usually pick one up at your local large animal veterinary supply store.

Interesting suggestion, Ross.

Let me try this and report back tomorrow.

Wait a minute - I think the noise is fixed!

I also took a can of silicone and sprayed around the area where the wheel meets the boot...so far no-creak!

Keeping my fingers crossed for a few more days.

Usually in the past - even if I sprayed around any bolts near the wheel area, the noise comes right back on...this time - after a drive out for lunch and back...still muted.

Ross,

This sound is back on again - on the same side.

I tried injecting gear lube into the lower rubber boot that is close to the wheel as well as sprayed silicone lubricant in/around the spring area and all joints near the wheel.

It feels noiseless until it goes over the bumps and then the noise stay for sometime.

Any other ideas or other areas that I should be lubricating here?

Appreciate your help again.

Thanks!

Seems that way, Mills. My mechanic had it on the lift and sprayed down in/around the bushing. The creaking went away for a while and now is back - the weird thing is, it feels so during a run and when it is stopped for a bit. It bothers me when it sounds that way at low speeds.

Any thoughts on how to get rid of it for good - without a complete replacement?

Find the bushing, loosen the nut, compress the suspension (best to put it on the ground), then tighten the nut back up with the weight on it ? Maybe ? I know this happend on my Porsche once . I put all new bushings in and tightened up everything while it was still in the air. When I put it on the ground the bushing was tight and twisted under suspension load. To fix it I loosened the nut with it on the ground. Worth a try .

Thanks for the thoughts, Mills.

ElectriCT - I felt the noise came from around this region too.

Is there any special lubricant that can help eliminate any possible dryness here - I've tried the CRC Heavy Duty Silicone Lubricant - hasn't helped much.

Appreciate your responses.

Adding a lubricant help only temporarily and is intended only as an aid to locate a noise (ball joints), it always ends with a new part.

In my experience if its a creak then its the ball joint which can be temporarily fixed with the injection method, however, it needs replacing. If its a squeaky creak!! over slight undulations in the road then its the inner rubber bushing, this can be temporarily fixed with WD or silicone but always comes back. I discovered the latter when I changed my track control arms a while ago, when I placed the inner rubber bush in a vice and moved it up and down I replicated the noise exactly.

Gents,

Got back the Box after an AC issue fix.

Just curious - is the ball joint replacement a DIY? If yes, can you point me to some instructions here.

Is this the part that requires replacement too?
