This is the year I'm going to try and fix that dang squeak.
I was driving the car yesterday and the squeak, squeak, squeak, down the road was really loud. Once again I could lightly apply the breaks and it would stop. I then did a quick lane change to the right and it went away completely.
One thing that I have wondered is if the retaining ring on the rear axle could be rubbing on the seal to make that noise. When I installed the axles and seal I was having a hard time with the seal depth so I just got the seal started and then use the retainer collar to push the seal in. So I'm going to pull the axle and check that.
At the same time I'm going to check the lube points for the brakes.
You hear what you are saying " Once again I could lightly apply the breaks and it would stop."
How could it be trim rings, or controll arm bushings if it goes away when you lightly apply the brakes.
I hear this all the time on cars with disc brakes when they need to be replaced It is the wear sensor that is attached to the inner pad. If you look at the pad there is a thin metal tab attached to it. When the pads wear down it rubs on the rotor making the squeaking noise, to let you know they are getting thin, so you can replace them before it goes metal to metal on the rotors. if you want to test what I am saying. Take your wheels off, look at the inner pad find the metal tab. take a screwdriver and bend it a little bit away from the rotor, and drive the car and see if it goes away. do both sides.
