NO just replace the one that is going bad. The wheel bearing are sealed bearing and when the manufacture of the bearing not put enough of grease in them and they dry out, that's when the bearings go bad. It's rear to have both side go bad, so save some money and just replace the bad one for now. I have replaced one wheel bearing on my dad's Yukon and i need to replace the same side again soon, so don't buy cheap after market wheel bearings. Try to stay with the OEM from the dealer or more expensive after market bearings.
Thank you for using fixya and be safe.

SOURCE: replace front wheel bearings

The bearings in your car are pressed into a hub. If the part is available as an assembly, it can be replaced that way. Generally on a front drive car:
Remove wheels and brake calipers
If it is pressed in: remove the rotors, disconnect the drive shafts and remove the steering knuckle. Then the old bearing is pressed out and the new one pressed in with a machine shop press. If the bearing is part of the hub, that will be unbolted and the new one swapped.

On a scale of 1-10 difficulty, Id rate it a strong 7

SOURCE: severe bearing noise from front wheel bearing/cv

you have to replace bearing and hub as a unit.you have to remove remove brakes and caliper rotor set them aside dont disconnect brake line. get a piece of clothes rack wire to hold brake caliper .do not let it hang by brake hose. you got to remove hub nut. best way to do that is loosen it a litttle while tire still on weight of car keep wheel from turning .

SOURCE: Replacing front wheel bearings

It isn't a particularly hard job but there are a few techniques that you need to know.
I wouldn't recommend you do it yourself but I would recommend you do it under supervision of someone who knows their stuff.
Retensioning the bearings correctly is extremely important.

I am reasonably sure there is no front wheel bearing on a front wheel drive car, the hub is usually splined and slides onto the drive shaft. I may be wrong but I dont think so.

Front wheel bearing adjustment


I don't think you will be able to adjust the bearing. You may check to make sure that the hub is on tight. Not sure if you change change just the bearing/race OR if you would have to change the entire hub assembly

Front wheel bearing nut keeps comming loose


you need to inspect for burning and wear. the bearings and races may have to be replaced. if all is good then apply a light coat of lock tight(medium grade/blue). this is not common place to add lock tight so please dont think this is normal. i would think the bearings are the likely issue. you dont need to get these from kia. a quality replacement will get the job done. be sure to use a good quality wheel bearing grease. cheers

Replace front wheel bearing is it hard to do on 2002 alero


its actually pretty easy if you have the basic tools needed and a little mechanical knowledge, because i dont think you can buy just the bearing at a auto parts store. they sell you the whole hub assembly which is great for the DIYer.

lift the car off the ground and block it from rolling and place a jack stand under it so it cant fall on anyone.

I Think I have a front wheel bearing problem


Check wheel bering for play if there is no play , it doesn't mean that bearing is NOT bad its can still be dry and would be making that grinding sound you described Also check axle and see if boot is broken. That may be your problem also make sure that rotors are not gouged/scraped up and pads are good.Contact if you need more help and thanks for using FIX YA

Noise in front end, sounds like wheel bearings, 110,000 miles, rear end axles and bearings replaced, sounds still present, louder when making left turn when weight of vehicle shifts to front end right side


You say the rear wheel axles and bearings have been replaced, you mention nothing of the front wheels, you have the symptoms of a front wheel bearing being worn out, remove them and check for pitting in the bearing rollers or the bearing races, I am sure you will find a problem. Hope this helps solve your issue with the bearing noise.
