How to Replace front wheel bearings
Monday, November 13, 2006 10:41 PM
Regarding a 1993 Cavalier.

Too cheap to buy a manual for a car that i'm only gonna keep for a few months, so here it is. I bounced the car off a curb, bent the rim etc. I put a new rim and tire on, but now the alignment is out pretty bad and I get a "bearing sound" from the front.

Now I'm guaranteed that I bent the tie-rod, but whats involved in swapping a new bearing on (or a complete spindal if its easier) Just the quickest, cheapest ghettoest fix. Not that the bearing sound bothers me, But my last vehicle got written off from a bad bearing...

Manuals are like 10 bucks at autzone, but its basically like legos, you just start unbolting stuff, then you get down to the wheel bearing and you PBblast the hell out of it andheat it up with a torch so it breaks free of the knuckle. Then you install the new one and reverse.

Jack the car up and take the wheel off. Take off the caliper and rotor.

There should be something like 3 bolts that hold it in, along with the CV shaft nut. Take the CV shaft nut off, pull out the 3 bolts. Here comes the fun part. Excuse my crappy MSPaint skills, but this is a good idea:



The red, that's the hub assembely. The blue, that is the end of the CV shaft. The green, that's a puller.

Position the puller on there like this, and slowly pull it off. Hit the hub occasionally with a hammer to shock the metal and make it come off easier.

When putting the new hub on, put anti-seize all over the part on the cv shaft that the hub slides onto, it will make things alot easier.

Any questions, PM me or whatever you need, I will gladly help.

Thanks. New hub assembly is dirt cheap, I've just gotta double check to make sure thats the problem.

I have a "humming" sound with little vibrations around 80km... I put different wheels on and problem persists. Now...

A) bent tie-rod
B) Bad front wheel bearing
C) bad rear wheel bearing (bit of play but In it, but It never got hit)
D) alignment is out and the tires are pushing towards eachother causing the noise
E) Mechanic said it could be that the bearings on the CV shaft got hit and could be the CV itself (doubting this theory)

In concludence, I hate replacing @!#$ that dosnt need to be replaced... but vehicles that rattle and shake piss me off.

On a side note: I feel the vibrations UNDER LOAD for the most part, but the SOUND is there all the time.

I would think a bent tie rod wouldn't make that noise although it could. I believe it's probably the wheel bearing. Could always have the car aligned and see if that changes anything. If that doesn't help the noise, atleast you know your car has a good alignment.
