Olds Alero 99 Left front hub assembly

I had the hub assembly changed for the fourth time in 2 1/2 years and it causing the same problems again and need it replaced again three weeks after having it fixed. What happens is: the low trac, trac off,anti lock lights come on dings three times then trac off low trac lights go off and the anti lock brake light stays on. Could there be some other under lying problem that may be causing this?

It sounds more like it's the wheel speed sensor that is part of the hub/bearing assembly. Since you have had the hub replaced many times I would look for the electrical connectors for the wheel speed sensor as the problem. An easy no cost fix.

BTW...GM has issued a service bulletin for the hub/bearing kit that states NOT to use the old style nut that comes in some kits as it will cause premature bearing failure due to it's design and the high torque requirements. The correct shaft spindle nut part number to use is p/n 10289657 and is torqued to 178 nm. The GM bulletin number is 03-04-18-001.

I found on some of the GM hubs it actually wasn;t the hub at all but a broken wire in the spped sensor harness about 8" back into the harness fixed the wire problem fixed.

Value Quality Parts most likely,not brand name quality
& improper installation

Repair shops use an air gun instead of a torque wrench,
to install the axle nut. Sloppy work

Front passenger wheel is in at the top by 1/2 inch rubbing noise started when making left turns. I think wheel hub assembly is bad. Also inboard brake pad completely worn down. Can bad struts cause this?


Sounds like a bad hub/bearing, could also be a front axle issue though.

I have never heard in my almost 15 years as a mechanic of struts causing one pad to wear uneven, this more sounds like an issue of one of two things, bad caliper, or when you had your brakes replaced whoever did the job did not replace that pad.

My 99 Alero has had the left front hub assembly repalaced for the fourth time in 2 1/2 years. I had it replaced three weeks ago and it has the same problem again and needs to be replaced again. Any idea...


Is the wheel bearing failing or the wheel sensor inside? Is the vehicle totally stock or does it have aftermarket whells on it? Some aftermarket wheels have the wrong offset and put excessive strain on the hubs if you have the wrong wheels change back to the factory wheels and see if your problem goes away.
