Squeek when backing up? - BMW Forum

ragdollop · 06-21-2008, 10:52 PM

I have a squeek that has just started when I back up. It sounds like it could be the brakes, but I pulled the wheels and checked them and they are good. Could it be a wheel bearing? It is coming from the rear. Not sure the exact spot though. It is not a constant squeek but one that gets faster the faster I reverse.

Any ideas?

Does the squeak sound go away or change when you apply the brakes?
You could try applying the E brake slightly to see if the sound changes etc.....

Also a bearing would make noise in forward as well as in reverse.......a bearing noise, is more like a rumble & vibration, especially at certain speeds!

sounds like you need Emergency brake pads and lube the shoes againest the backing plate...

V he said he looked at the brakes....

i think it's time for some brake inspection, don't u? :-)

if u pass brake inspection... then, it is something in the bearings or hubs ;-)

but... i am of the same opinion as alpine6&7... "the faster and faster as you reverse" means something touching on the brakes or rotors...(usually a backing plate bent out of shape.

Yeah I checked the brakes. I had the car on jack stands and put it in reverse and the noise seems to come from the rear of the car but towards the middle. I cannot pin point the noise but unless it is missleading me it doesn't seem to be coming anywhere near the brake discs. I sound close to the differential or somewhere near it. It is just hard to tell where. I might just have to take it to a shop.

Might be a universal joint.

i have a feeling your rear pads are wearing thin... there is this metal "feeler" that is attached to a brake pad that touches your rotor when your pads are too thin. It is a warning signal actually that your brakes need attention.
