I just did the rear brakes on a 98 sonoma (has a limited slip axle). On one side, the caliper bolts were seized (I understand this is common with rear discs). Anyway, the brakes on that side were always pushing the axle outward. Now, with the new brakes, I am getting what sounds like excessive tire noise (I say it has that type of sound). I checked the end play on each side of the axle. The side that originally had no brake problem was tight. The side with the seized caliper has about
1/32 in/out play (you can get a nice clunk-clunk when pushing it in/out). I don;t expect anybody to completely diagnose this problem, but since seized rear calipers are so common, do mechanics typically expect play and noise after fixing seized calipers?A couple of other things.
-The noise is at all speads and gets slightly louder as speed increases.
-The noise DISAPPEARS when going around a right hand curve on the highway (this would force the axle outward as if the old seized caliper was pushing it outward).
-There is no noise or binding when the vehicle is run on jack stands.
The thing that really makes me think that it has to do with the end-play, is the fact that the sound disappears when going around a right hand curve.
