957 GTS 37,500 miles. I’ve been tying to hunt down this tick noise from the rear of the car for a week now. It happens at slower speeds and uneven pavement.

11 second video of the phantom tick. happens after I stop the car.

after some research, it may be the axle that is ticking. I didnt find any videos of cayennes but I found a ford making the exact same tick sound, as well as a 350z. we shall see.

That was also my guess....CV axle. They get dry spots and the joints makes noises. Try grasping the boot with both hands and squeeze gently, in an effort to re-distribute the grease better.

Vivid7

thanks. I’ll try that tomorrow. I only get a few ticks when I’m under 10mph. it’s not constant.

Vivid7

Tried squeezing the boot to draw more grease to the joint. no dice. Still ticks when going slow.

I’m just going to replace the axle. Are the 08 Toureg axles the same as my 08 GTS? I would think they would be. They are much cheaper.

FYI.... swapped a new axle in and the tick is still there at low speeds and at random times. 1-3 clicks and then nothing. Putting in new brake pads tomorrow. either a pads issue or an E brake issue.

Hate trying to track down noises like this. Just narrowed a clicking noise down to the blower motor, replacement on order. Not to hijack, but anyone have an educated guess what could be squeaking like old bed springs on the front right quarter? Probably not control arm related, uppers and lowers both replaced about 30k miles ago FWIW.

Just replaced rear rotors and pads. Tick is still there. I can recreate the tick every time going about 20mph and slightly jerking the steering wheel to the right and then left. Happens on the left jerk every time. The new brakes feel great and no more brake dust.

There have been a few posts elsewhere about Range Rover suspension sounds.

The poster attached a camera with a magnetic mount, to the frame in the suspect area. Problem was isolated and corrected by a dealer.

I just bought a iPhone mount about 30 min ago. I WILL find and fix this.

Here's a completely different idea. Should be easy to check. Had this on my 2004 S, while my brother in law owned it, just after he got his 22" wheels.

The problem was that some hardware had come loose inside the wheel, i.e., in the cavity between the wheel and the tire that is pressurized with air. Probably a tiny little nut or something that would rattle around. It was from shoddy work by the wheel builder or tire installer. I remember helping by running alongside the car while my BIL was driving, listening to isolate the source.

At higher speed, the centrifugal force keeps the rattling object fixed against the inside surface of the tire, rotating with the wheel. At low speeds, it bounces along silently against the tire, just above the road surface. So you only hear it at the speeds in between (luckily for me, right about running speed) where it is not pinned against the wheel, and bounces on the top of the wheel, making a little tick / clink.

Simple test is to swap the wheel to another location and see if the sound moves. That should be cheap (free) and easy to do.

Excellent idea. I just read a post on a RRS that had a part of the TPMS sensor break off and rattle around.

Good video there. Yes, that sounds like a foreign object within the wheel/tire.

Tough thing with my BIL's car was that the problem was present on 2 out of the 4 wheels, making it even tougher to figure out. Good luck with yours.

Oh, now that would be annoying to track down. Never considered that happening, know we know one more weird noise to listen for...

I'd much rather not use my phone... one more thing to have to fix/swap/upgrade if it falls off. GoPro is probably more durable.

Here is a new video. Definitely in the back 1/3rd of the car. At 18 seconds I move the steering wheel from left to right.
