hi all. I discovered my rear axle seals are leaking bad on the right side of my 68 fury. I'm guessing I have to deal with the bearing adjustment when I take it apart?

It's no big deal to adjust it.
I'd change the other side too.

I was figuring on doing both sides. I just was hoping the noise I heard last night was something easy to fix.
The other thing to check while you are at it is the vent for the rear axle. These sometime plug over time and will cause an oil leak because pressure builds up in the housing as the assembly warms up. If the vent is plugged, the oil is forced out thru one or the other of the bearings. If the brake linings are oil soaked, they will need to be replaced. I would suggest jacking up the car to see if the bearings are out of adjustment before pulling everything apart as this helps make the diagnostics easier. If you have a noise coming from the bearings, odds are one or both is failing.

I pulled at the axle flange on the right side and there is very little play. I haven’t taken off the left side since I’m scared at what I might find
Bearing adjustment is covered in the FSM. Download for free at www.mymopar.com. Manuals are in the Tools/Reference section from the home page.

Also keep in mind that these old Mopars have packed wheel bearings on the rear, so as you disassemble and inspect, be sure to repack the bearings old or new with wheel bearing grease. FSM covers that as well.

Ugh!!!!! Just took the drum off the left side and there is quite a bit of play in and out as well as up and down. I guessing the bearings are done
Note that with the other axle removed that removes the tension from the bearing, pull it out for inspection.

Make sure you put real Timken bearings in, would not want to see you have to do it again in a couple of years.

I adjusted the bearings and it seemed to take up a lot of play in the bearings. I took out the right side first and the left side. I cleaned them and looked at them and they seem to look ok but I did see a cut in the bearing race on the left side.
Wow! Never saw that happen!
The bearing races are hardened and that's a crack. No going back for that one... It needs to be replaced.

AAArrrggghhh!!
Check the bearing seat in the housing for gouges. It is all but impossible for the outer race to break unless there is something bad wrong with its seat.

Thank you everyone for the info. How do I get the inner seal out without going crazy?

Ok. Just got the left seal out. How does the bearing surface look? This is the side with the cracked race.
Those look like machining marks as opposed to scoring, so it probably is ok. In a perfect world, you could mic the seat to see if it is the same as the other side, but it does not look scored to me.
