How do I change rear axle seal?

The car is a 68 Lesabre, I need to change rear axle (or wheel) seal. I havent done anything but determine the problem. few questions:

1: ofcourse I need a new seal, but do I need to buy a new bearing also?

2: Hows it done? Do I need to take the brake assembly off also?, When I get the axle out, what then? Is the seal just slipped in there or what?

THANKS ALL!

 

Before anyone freaks out because I posted a Ford 9", this is just for illustrative purposes. The basic design for the axles and seals is similar enough to illustrate where the seal lies and what would have to be removed. Maybe this picture can give you an idea on what you're going to be tearing apart. It's not hard, it's just a matter of making sure you don't have any left over parts when you're finished.



If I can find an actual GM 10-bolt I'll post it up.

I just did my '68 LeSabre. Yes, you will need to remove the brake assembly (4 bolts hold the backing plate/axle to the housing). Once you pull those 4 bolts, you should be able to pull the axle out of the housing (with a little bit of help). Once the axle is out, the seal is just inside the housing... it's easy to get to and easy to remove/replace.

The bearing will stay on the axle. I believe that once you go through all this work, it is worth it to replace the bearing. If you do so, you will need to remove the old locking collar and press the bearing off the shaft. Most people cut the old locking collar off. The bearings are not cheap! Do some research... I found NOS on ebay for about $50 each.

I love this forum, this is just the help I needed, these tips are worth gold, I placed an order for the seal, seems like changing it will be a snap, THANKS

 

This may be a little late in coming, but should still help. Just remember that you shouldn't have to deal with C-Clips and that your axles have a bearing retainer plate. Otherwise, it should be the same basic steps.
