wheel bearing questions

[mazdamama]

i just bought new wheel bearings, brakes, and rotors, for my 94 4 wheel drive and ive run into some difficulties .the bearing packs i purchased came with the A37 front bearings and like an outer cup or race the bearings fit into, however it looks like the rotors i bought come with a preinstalled race for the bearings to fit into, and if i try to put the new bearings and cups into the new rotors they dont fit. the way i have installed them now, seems right to me, but it doesnt look like this diagram http://img511.imageshack.us/img511/6513/0900c1528018f0b3pn0.gif so what im asking is if anyone else has run into this situation and what should i do? is it ok to run the bearings inside the rotor without the cups that came with them, seeing as how they wont fit anyway?

is it possible that some newer rotors have the races allready built into them?

My new rotors came with new races. However, I installed new bearings at the same time and I just don't have very good luck, and to reduce anything going wrong, I used the races that came with the bearings.

Bearings aren't matched to the races, and yes the rotors will have races already installed in them. Just use the rollers that you bought with the races in the rotors.

It's always bothered me to run races that may not be the same brand as the bearing cones. If it were mine, I'd also swap in the races that the bearings came with so everything's the same (especially if you bought good quality bearings such as Timkens)

I used to think that aswell. When I get bearings from the part department at work (ford dealsership) You get the bearings and races seperatly, and they are not always made by the same manufacturer, some are skf, some are timken. Never been any problems.

Don't replace the cups in a new rotor.

What about with "parts store" replacement rotors? (I only wonder with so much chinese garbage floating around out there nowadays)

awesome thank you guys so much i didnt want to throw it all together only to have the bearings explode again. this time when the bearings exploded it caused the wheel to wobble so bad that it snapped the brakes calipers off, broke my manual locking hub and chipped the crap out of my rotors, if i just would have spent the $15 dollars to replace the bearings earlier, i wouldnt have had to spend the $200 to replace everything else.

one more question: how would i remove the old races from the rotors next time i redo the bearings?

With a punch. There will be a couple of notches in the rotor so you can get a punch on the backside of the bearing race.
