How many miles on the car? Is the noise coming from the rear or front? Rear squeaky noise could be the start of a bad u-joint or a brake disc pad.

Classic symptom of a bad U-joint.

If the roller bearings get rusty the cap can't turn and the cap turns in the clamp, which makes the squeaking noise.

first, pull the wheel and check the brake pads - sounds like a wear indicator. if its a pulsating squeak sound, it could be caused by a slightly warped rotor. does it go away if you lightly apply the brakes? the reason it may seem to go away, the faster you go, could be, you're just not hearing it for the road noise.



if brakes are good, try to isolate the noise - could be u-joints or bearing/hub assembly, but my best guess, most likely, it's the brake pads.

Thanks Joe, I will check the rear pads, I have a low pedal also may be the problem.

Do your new u-joints have fittings so you can grease them?

Cool. You can grease the occassionally. Sometimes it's a little tricky to get the tip of the grease gun in there, but if you rotate the axles you'll be able to get it done. Best news is you'll never have to replace them again!
