Alright...I've been reading into this for a while trying to figure this out. My MY01 AP1 made these noises before on both driver's side and passenger side rear wheels and I've replaced both rear wheel bearings (at separate times) this year. When I replaced those the noise went away both times and after a trip to the Tail of the Dragon in October, the drivers side started making the noise again. Took my S to the shop where I had them replaced before and they replaced the driver side again...didn't even get out of the parking lot and it still made the noise. They told me they couldn't hear it when they drove it and, they're friends of mine with a reputable shop...I really want to trust that they did replace it and know what they're doing but I just cannot figure out what this noise is...

I also told them about the axle nut tsb. Usually I do my own work on my car but I didn't have the time this time...see what happens



I've included three separate videos...don't worry, they're short and the longest one is just over a minute long. Please help!

Nobody? I'm in dire need of some help here. Ruled out the axle and wheel bearing. Next step is change the diff fluid and grease the slides in the caliper...

Still looking for help from anybody that has experienced this sound and fixed it before...

 

Wish I could help but have you replaced the rear brake pads? Maybe the driver side is dragging?

 

Could also be the brake back plate

 

Thanks for the replies. I'm gonna take a look at the brakes in the morning.

S2KPUDDYDAD, I'm not exactly sure what you are referring to? The shim on the pad itself or something else?


I forgot to mention that the noise goes away when I apply throttle but comes back almost immediately after letting off. Also, wanted to mention that the noise gets louder the longer I drive it and I can now hear it (driving near a wall) at highway speeds. I'm not sure if that helps but wanted to include my observations so far.

 

Could be any one of a number of things. If it were my car:

1) Jack up driver corner and with the car in neutral hand turn the tire. You should be able to hear where it's coming from
2) If it's in the outer area remove the tire and raise the calip - eliminate or verify brake is the cause
3) If noise is still there get under the car and have someone turn the hub. Determine if it's a bad bucket, diff. Etc.
4) If no noise the issue may be related to spring seating (not sure if OEM or aftermarket on your car)

You should systemically try and find the noise. Driving in circles and asking what this sounds like won't get very far in fixing the issue IMHO

My apologies. The videos were for reference purpose for anybody that might recognize the sound and/or future issues so that people may find this thread and hopefully find their answer after it's solved.

I should have made it clear that I've had it up on a lift several times, visual inspecting and rotating the wheel and there's nothing there. No weird vibrations, the sound isn't there. I've also taken it back to the shop where the bearings were replaced twice now since then to have them go over it. Today, actually, they took it in and put the axle under load (not sure how as I was not there) and told me that the noise wasn't to be heard anywhere.

It's giving me quite a headache as I'm trying to pack all my stuff by myself for a move while dealing with this at the same time.
