I replaced my rear bearings a little over a year ago. Only problem was that now with the wheels in the correct postion, (with new bearings) my alinment is off. Need to have the alinment done again.

Used my 20ton shop press. Took less than a day.

 

Yeah I buy only mazda parts so they will be exactly oem spec... I gotta learn to stop paying $1.20 for a lock washer ... :-/ but yeah the bearings I'm gonna use will be OEM but I just want to make sure they aren't funky once they've been pulled once or something... :-/

 

The average lifetime for rear wheel bearings is about 100K miles...some will last longer while others will go less. Your bearing's short lifetime is probably a result of damaging it during installation. During installation, never cause a radial stress to be applied across the bearing. If your pressing the outer race on, than apply an axial force only to the outer race. If your pressing the inner race on, than apply an axial force only to the inner race. Make sure the outer race is bottomed in the aluminum housing, and that the hub is bottomed in the inner race. If you take your hubs to a full service auto parts store, than the store will usually be able to press the bearings on for a small fee...probably free if you buy the bearings from the same store.

Rear wheel bearings will normally last longer than engine and transmission as mentioned below. I owned a 1988 and 1994 RX7 non-turbo with over 200K miles on each car and no problem with rear wheel bearings - all front/rear wheel bearings and suspension are pretty much bullet proof if you maintain car and do not hot rod it.

Umm, 2 things. Correct me if i'm wrong (I really dont think I am), but aren't all FDs (93-95) twin-turbo. How do u have a 94 non-turbo? Second, do not hot-rod it? Thats what alot of these ppl buy these cars for, lol. On my 87 SE, and my current 88 GXL (which has 150k on it, gonna get new motor soon) the bearings work fine and I still hot-rod em. Notice: hot-rodding doesnt mean generally not takin care of your car. You can "hot-rod" it and still keep it in good condition as long as u do it right.

 

I replaced both rear wheel bearings on my car with Timkin bearings from the auto parts store. It has been 2 years and almost 30K miles and have had no problems.

 

Don't get the bearings from mazda, I got mine from NAPA and it was WAY cheaper
