Hey Guys,

I have a 2006 Mustang Gt and have over the last few weeks noticed a noise that seems to be coming from the passenger side rear wheel. The noise only manifests itself as a repeated squeak that seems to coincide with wheel rotation at low speed after being parked for at least a couple of hours. In April, I had the rear calipers, pads, and rotors replaced, so I'm not thinking its the brakes. I was under the impression that a wheel bearing noise should be present all the time and it isn't. The noise gets quieter as a I drive down the road to where I can't even hear it at all (this is at a constant speed under 20 mph). I jacked up the rear and slowly turned the wheel by hand, and the noise appeared to be coming from the caliper area, but I'm no sound expert....So I'm just confused as to what it is. suggestions?

EDIT:

After some research online, I'm finding that these are all possible:

1.Possibly need to add friction modifier to the diff
2.Wheel bearing wearing out (but I think the noise needs be present all the time, mine isnt)
3.Sway bar or lower control arm bushings needing grease
4.Rear Brake cable needs graphite
5.Exhaust hangars possibly loose
6.Rear caliper pistons need centering
7.Lower control arm bolt loose
8.Loose rear shock or strut

Sheesh... I've got a lot of things to check... I would suspect the wheel bearing if the noise were present past a couple of minutes of driving, but it goes away. It also might just be the brakes not clearing the rotor all the way until the power booster warms up, I guess. Still open for input here....

if you think it's coming from the caliper, take the caliper off and rotate the wheel by hand again. if you don't hear the noise, the caliper is the culprit!
