Had a rough night trying to finish rear bearing/brake job. I am regrouping this morning.

Had no issues on driver side. The passenger side is giving me a couple problems.

1st is the races. Or at least one outer race. They all went in with a bit of a fight, as I do not have a press. I just was hammering then in as careful as I could with a bearing race driver. The last outer race with cockeyed on me and ended up messing it up. Luckily found a new one and will try again today. I am trying to fab up a threaded rod so I can kinda press it in place and ry to keep it square easier. But no fine treaded rod at the store.

Next issue was i went to out on a drum and the inner bearing did not go on. Kinda stuck. I screwed up the seal pulling it back off(came off with a fight). I tried test fitting the other bearing and both spindles same issue. I have to carefully remove the bearing that i pushed a little on by hand and cant seem to pull it off yet. The old bearing goes on. Kinda tight to start, but pops on. And you can remove it by hand with a good yank.

So I think I need to just use some scotch brite and clean that spindle a little??


Any other advice?? This is all timkin bearings. Driver side went together normal.

My other issue, looks like no local timkin seals. Napa one works right??

Chicago Rawhide seals work well.

The real fuss about the Seal for the rear is the metel rubbing against the
roller bearing and possibly giving off metallic particulates.
I do see the importance of this, however sometimes one needs to use what is
available and realize it is a issue, but nothing that will
drastically effect the life of the assembly.
If things were that sensitive, the solvent, room , rags , tools,grease and
the worker better be using Clean Room Protocol .
I'm sure some will argue this, but it is my experience.
On or Air Filtre side, I teach Clean Room Procedure so ....

Napa 21771 seemed to match the timkin.

Used a scotch brite on the spindle and that took care of bearing fit.


The race was struggle. I out it in freezer. Left my heat gun on the drum for a bit so it was warm to the touch.

And used my home made threaded rod press. It fought the whole way and took a little impact, and tapping micro movements at a time the whole way down into the drum. I just took my time and was carful not to mess up the new race.

If you want to drive that race in straight you can use the old one upside down to drive it ....keeps the new one flat because its driving in the bore BUT take a few minutes with a grinder or dremel and cut a couple grooves in the old race (in the bearing surface) so you can use a punch to drive it back out.

The "trick" I always used for races was put the new ones in the freezer when you start the job they may only shrink .0005 to .001 but that helps don't use this on front wheel bearings. Make sure they come back to normal temp before tightening.
