getting front wheel bearings out?

Post by timspider »

does anyone know of any specific directions, preferably with some kind of visuals, to get the inner bearings out of the front wheel hubs?
I've watched the zoubiando one many times and while it's a good video, it kind of glosses over the part about exactly how to get the inner bearings out.
I've got both front hubs off and the outside bearings just came out in that process.
I know there is an inner grease seal that comes out and gets replaced. I can see it but don't know how to get it out.
I guess there is some kind of a snap ring spacer somewhere in there? Can't see it and no idea how to get it out.
I see the outer race that held the old bearings- I guess that gets pounded out with some kind of drift from the other side?
I probably need a video showing what to pry on and what to smash on.
Have wasted enough hours trying to figure this out myself. Need someone now knows.
Any help is appreciated.

You just pry out the seal by the sheet metal rim and toss it in the trash and the bearing just about falls out into your hand ready to be cleaned and repacked. Its the same as just about any rear wheel drive American car made from about 1940 through the current day.

Just look at the new seal and it becomes pretty obvious. Some companies even make a seal puller pry bar just for removing the inner seals.

In this video you see the bearing almost jumps out just from the suction of the grease on the seal. If you are going to clean and repack them then this is all you need to disassemble.

The video Diesel provided is a good one. Only thing: I used the same tool as the video, and it did rip the outer metal surface of the old bearing. Maybe I was clumsy; don't know. But the seal gets pitched, and a new one slowly and gently tapped back in using brass punches and patience. Follow the video, and don't fret about the old seal.

There's a couple of good videos out there on repacking bearings as well. I used colored zip ties to keep each side's bearing sets together (in their order of assembly), then soaked the sets in clean thinner for about a week (while I worked on other things). They came out of the thinner absolutely clean; open air (no powered air) dried them on absorbent towels for a couple of days, then repacked them using a Lisle bearing packer. Much easier than I feared, and very satisfying when they spun smoothly and quietly once back on the axle stub.

I highly recommend Richard Ridge's control arm FAQ from the Mirafiori site. He has a clear, sequenced explanation of reinstalling the front wheel bearings:

Might want to look into getting a torque wrench which goes down to 5 ft/lbs (or 60 in/lbs) for the final wheel bearing nut installation. Go slow, double check, and keep things in order, and it'll come out fine!

Also watch out for the videos that present the wrong way to hand pack a bearing. If they are not scraping the edge of the bearing across the palm of their hands so that grease is being forced up between the rollers filling the insides then they do not know what their doing. If they are just smearing it on the outside and spinning the bearing in the hopes that some gets in then move on as that is not correct and will result in premature failure of the bearing.

This demonstration by The Farm Journal is pretty good and shows the correct way to hand pack a bearing:
