Rear wheel bearing failure, replacement.

I had a massive failure of the rear wheel bearing, at least 2 balls are chewed up and it dumped diff oil all over the place. I did a search, and looked at info and it looks like I will need to get the bearing pressed off, I don't like the "pound the axle on concrete" solution. My questions are:

1. How does the ABS thing come off the axle? I can't find a clip or anything.

2. Since this has been a massive failure, missing balls, is this going to make getting the bearing off the axle a problem? Will it make getting the bearing out of the carrier a problem?

3. Should I do both sides? The drivers side is the bad one, but there is no fluid leaking out the passengers side.

4. Are these sealed bearings? They look it.

And any other advice would be appreciated.

You had no notice no noise no grinding before this happened??

As to your question Maybe ??? One never knows.

The Abs part just slides on and off.

I myself would do both sides maybe even pull the gears out for a good cleaning

We all do things different just as easy to get them both pressed off and on at one time.

It's my son's truck, so I had no idea. Now it is a learning experience for him. And a lot of work for me. Thanks, I think I will do both sides. How hard is it to remove the gears and check them?

Thanks again.

The hard part is getting the axles and brakes off which must be done to replace the bearings.

disconnect the driveshaft unbolt the carrier if it has the stock rear end.

slide it out

like all else you really don`t want to be doing this in the dirt or sand.:jessica::jessica:

Get plenty of kerosene for cleaning the gear oil off everything~

I'd have them pressed out by a shop, but you can CAREFULLY use a cutoff wheel to cut them enough to get them off by hand. New ones have to be pressed back on.

The cutoff wheel sounds good for removal. The ABS thing just slides off?

Why cut them out. Just press them out and then press new ones in. It took a lot of pressure to pop those axles off my old bearings. Can't visualize how you would go about cutting them off. You can get it done in less than 3 hours if you have a press avalable.

There was no way of cutting them off that I could see so I just took it to a machine shop, gave them the bearing and seal, and I'm getting them to do it. I have to clean out the housing and the gears then re-assemble. Getting the drums off was the hardest thing, there was a lip and it was hell.

Got the housing cleaned out, the gears checked out fine. I assume you can only install the rear gear one way? I got them on, hopefully not upside down. The number is stamped on the upper right side looking front to back.

Pressing off that bearing and ABS gear is the only way to get it out. I just took my rear axles apart on my 83 and trust me, I was a PITA even with a good press. That bearing cup cleans up well with a wire brush too. Also, I'm not sure if you removed it prior to taking the picture, but there is a retaining c-clip that goes on the axle after the ABS gear. Make sure that you aren't missing it or you might be rolling down the road on three wheels soon.

You definitely want to do both sides as well. Low Range Off Road is the cheapest place to get the rear bearing kits.
