Re: keeps chewing wheel bearings
I'm not familiar with the style of this rear bearing, there are 3 basic designs that are generally used. The single most important thing to consider when installing any of them is preload torque. Obviously the bearing must be properly lubricated and protected with new seals when installed, but the whole job comes down to how tight that big gland nut is when you finish the job. Because the Festiva is really a Mazda, I would cross check the final installation torque of that nut between different spec sheets and see if some answers can be found there.

#1. A wheel bearing should not lock up the rear end. #2. Sounds like you have a far worse problem, probably in the differential. To replace the wheel bearing you need to remove the diff cover, take out the spider gear pin remove the locking c clip and remove the axle. Obviously the left rear wheel and rotor and caliper have to be removed as well. then the bearing ,which is pressed into the housing needs to be removed. If the bearing is that bad the axle will need to be replaced as well.
bearing failure occurs mainly from several things .1 will be excessive preload ( over tightening the nut or missing spacer between bearings. 2 will be incorrect grease . 3 will be excessive amount of grease ( excessive grease will overheat the bearing and together with excessive preload will cause quick failure. 4 unbalanced wheels and faulty cv joints cause brinnelling which destroys the bearing Personally I would look for a missing spacer between the bearings or an incorrect size spacer.
Disconnect the wheel speed sensor electrical connector (2).Installation Procedure
Connect the wheel speed sensor electrical connector (2).
Install the wheel bearing/hub. Caution: These fasteners MUST be replaced with new fasteners anytime they become loose or are removed. Failure to replace these fasteners after they become loose or are removed may cause loss of vehicle control and personal injury.Notice: Refer to Fastener Notice in Service Precautions.
Clunking? Probably one or both wheel bearings. Dude, that car is like UNSAFE to drive!! Jack the rear of the car up and yank on the wheel. If it moves the bearings are bad. Pull in and out and also pry up and down with a bar. Check for broken or bent rear suspension parts, or just plain worn out bushings.
It,s probebly that the knot that holds the bearing in plase is being plased too tight, It,s the oldest trick in the book... this way you will have return about every two or tree months to get it fixed, and so the mechanic can keep eating.
