How hot should front wheel bearings get?

[unioncreek]

my son has had his 1993 Explorer Sport for about two weeks now. We replaced the passenger side front brake rotor and pass on both sides. He said today it smelled hot off and on. He said he could only touch the auto hub for a few seconds. Ive never had a wheel bearing get that hot. Could we possibly tightened the bearing too much?

i would look to see if the caliper might be hanging up. over tightening the bearing will wear it out prematurely but shouldn't get it that hot.

My son checked it after driving a while and he said it's the right front brake. How do you keep them from hanging up?

The pistons in the caliper are sticking. Best option is get a new line and remanufactured caliper and toss it on.

Brake line is new. I'll tell him to get a new caliper.

+3. NAPA's Eclipse semi loaded rebuilt calipers are relatively cheap, and usually available locally with a lifetime warranty. Bleeding required since you will be removing a brake line. As with all brake parts, replacing both sides highly recommended.

x2 on replacing both sides. If one has failed, the other might soon be near death. Do them both and be happy for thousands of miles.
