2000 suspension squeak - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Hey all, can someone watch the video and tell me what this noise is. History: car has 115k miles, and I personally neglect all of the maintenance, so that I know I'm responsible for not doing it. I recently replaced the track arms and drop links in the rear, and bled the brakes while I was there. This noise showed up around that time, but I'm not sure if it's related as noise started about a month later. The pads, rotors, rear struts and all bearings are all old as hell, but not sure where to start.

The noise sound like seagulls on the passenger side, not sure if front or back. Is present as 5-35mph. Doesn't happen every time, but moreso lately, 80% of the time. Car being warm/cold has no bearing. Clutch in out has no affect. Brakes and ebrake have no effect. Turning, accelerating or decelerating have no effect. The video has me turning off engine and coasting in neutral from the 10second mark to the end, so not engine. Speed doesn't change the tempo or rhythm, but it does completely stop making the noise below 5mph. Above 40 it isn't audible, but might just be washed out by road and engine noises.

I sprayed lithium on all the new suspension parts and sway bar, no effect. I pressure washed the brake pads, no effect. If anything, after I sprayed lithium and washed the pads, it might be worse or more consistent.

Update, I stuck my head out the window, and it coming from the front, so it's not from my rear suspension updates. The front suspension was rebuilt about 4 years ago so I don't think it's that. I've seen some videos of glazed rotors making the same noise, but visually they look fine. I guess I'll take the pads off and see if they are glossy

Before you take stuff apart, check if there is some peace of wood or gravel stuck bitween brake dust shroud (metal sheet behind the disc) that would be rubbing between the disck and this shield.

Another could be that some loose item from ground hit the same shield and bent it slightly (or shop did during some maintenance work) to allow it to scrape slightly on the disc.

If anyone is chasing this, it was a bad wheel bearing. Every article said the bearings howl, but mine squeaked. It was a bear to replace, but it did it all with AutoZone loaner tools. The YouTube tutorials that show how to do it without removing the wheel carrier help a lot. But, you almost definitely need to use a slide hammer to get the front hub off.

Yes, it is indeed a bear to replace, specially the front bearings

About ten years ago, I asked my older kid for help as I found out (very quickly..) that I didn't have the physical condition to do it.

Hopefully you replaced the four wheel bearings as the other ones have the same mileage as the one that failed..

My wife jumped a curb with that wheel about a month ago, so I'm gonna let the other bearings go. I suspect the whole car is going to implode in about 6 months anyway. 120k miles and 20 years of living outside in Louisiana/Arizona and Texas.
