metal on metal squealing

zoot23 · 10-01-2009, 12:17 PM

My 85 Mr2 has got a metal on metal squealing coming out of the rear passenger side wheel. The hub lock nut was loose because I didn't tighten it down enough when I put new boots on cv joints about 10,000 miles ago. I tightened it and the sound increased dramatically. In all probability is this the wheel bearings, cv joints, or side gear shaft? Anyone? (ebrake cable was stuck on that side for quite some time also).

Have you checked your brake pads? A bad bearing won't make much of a "metal on metal squealing" but more of a "howling" sound. But everyone describes sounds differently.

To check for a bad bearing just jack the car up and try to rock the wheel back an forth/side to side. If there is ANY free-play whatsoever its a bad bearing.

You should be able to tell if your brake pads have any life left by looking at them...

i had an issue where my rear driver side caliper had locked in the closed position causing it to rub against the brake rotor. jack it up and see if your wheel spins freely.

I've been through the whole sticking caliper thing. That's not it. The wheel spins freely in neutral with the e-brake disengaged. I'm pretty sure I have located the culprit. When I checked on the pads on that side I removed them last time. Apparently somehow I lost a little anti rattle spring on the top of the inner pad. This was causing the pad to be loose and rattle against the rotor. I'm lucky I didn't screw anything else up. Though it looks like there's a tiny chip on the edge of the piston. We'll see when I get the brake hardware kit. Thanks

fouled again. metal on metal squealing is back and worse than ever. Parts to brakes were never there in the first place. Lucky I didn't run into a concrete center divider in a turn at 100 mph+. (Something I used to do for fun).
