so im replacing the rear wheel bearings and seals right now on my 10 bolt. i got one side out no problem and pounded it in. everything went fine. easier then i thought.

so i go to the other side and pound the old bearing out with a slide hammer. easy. i get everything setup to put the new one in and the little f8ker wont go in. same with the old bearing. i cant even get that one back in. i have the BFH mod but still nothing

will putting it in the freezer for a night help or what do i have to do?

Are you sure you don't have any burrs on the axle tube? You might have to radius the edges a little bit.

They did give you the right bearing? same number as the other (on the bearing itself, not on the box). Size it up against the old one that you took out. measure the O.D.'s with a caliper if you have one. Other than that, just make sure you are going straight in.

yeah its the same exact diameter and everything. like i said i cant even get the old bearing back in. so it must be a super tight fit on that side :(


heat expands metal and cold contracts it, correct?

Yup. Try putting the bearing in a ziploc bag and stick it in the freezer.

freeze the bearing and just before install heat the axle a little with a heat gun or carefully with a small propane troch.....

Find the problem.
You don't need to freeze or heat anything on these rears ever. And in a home freezer? LOL, come on. Thats maybe zero degrees?
When machine shops do this type of work they use liquid nitrogen which can freeze the parts down lower than -320. Thats approx 320 degrees lower than what your bearing is going to be.

Like I said, you never have to do this on these rears. Find the problem.
