Rear Bearing and Seal Replacement. Still Leaking After Repai

[W1K1]

FYI
using an impact to install new bearings will cause false brinelling (vibrating the bearing housing and balls causing dents in the bearing race) which shortens the life of the bearing. Kind of like taking an axe to a new asphalt road causes pot holes.

Took the time after work to check the torque with a nice 250 lb. torque wrench. Driver side was not torqued enough. Passenger side was torqued enough.

After getting the drives' side to spec + a little and the passenger side + a little, I took her for a drive. No luck. Still leaking.

I have a new set of rebuild kits coming on Wednesday. I will take it apart this weekend, check everything over and add the gasket behind the backing plate. Hopefully that will take care of it. I'll keep everyone updated.

How do these look? The last time I did this twice, it was their fault. Barely worn can cause issues.

Edited due to double post.

Good idea. Good luck.

This is a timely thread as this job is in my near future. Good to know especially about the second paper gasket behind the backing plate - as OP mentioned it's not shown in Bentley even though it is included in the rebuild kit.

I had the same problem a few years ago. Replaced the seals twice, then a good friend suggested I check the bearing cover. Somehow it became slightly warped and didn't sit flush. A few runs with a file and sandpaper, I was good to go.

Where is the vent on a 66 manual? I am still having leaking behind the baking plates, and I want to make sure there isn't a clogged vent.

I took the time to take everything a part today. The leaking is confined to the backing plate. Inside the drum, behind the hub, was dry and clean.

The bad news is that the installation of the missing gaskets did nothing to effect the leak. It looks like I leaking exclusively at the seep hole.

So, is there a clogged vent that is causing the fluid to find the path of least resistance?

Can you post some pics of your parts once it's taken apart and cleaned? All of the pics you've posted have been external. I'd like to see the internals...all of them. Something like the exploded view in the Bentley.

Many of us have done this job with no problems, but a picture is worth a thousand words sometimes.

There are quite a few photos to be found in the gallery, but I'd like to see your parts...Thanks

Here is a picture of the seal kit i used.

A new set of spacers are in the mail. I'll take a picture of those once they are here. I will only be using the new front spacers. I don't think it will be advantageous to pull the bearings again just to replace the rear spacer. I also don't believe the bearings can be pulled without having to ruin them.

I will get a picture of the spacer kit once it comes in this week. I plan on pulling it all apart again on Monday. I have plans for the weekend that get in the way of any car repairs.

Here is the info on the bearings I ordered from rock auto.

For fun and consolidation, here is a picture of the exploded view.

Ok. The new spacer set came in today. I am noticing that both the small and large spacers are tapered on one side. Here are the pictures.

The small spacer goes in before you put in the bearing. Is the taper (larger ID) supposed to face the bearing or is the non-taper (smaller ID)supposed to face the bearing?

The large spacer, that goes on after you put the small o-ring on the axle shaft, I assume would have the taper (large id) facing the bearing so that the oRing has a place to fit?

These are my concerns. I KNOW that I put the large spacer in with the taper towards the o-ring. I cannot remember which way I put the small spacer behind the bearing. I will be able to check which way the taper is facing when I have everything apart next week.

I'm looking forward to some guidance on this. My thought, because of the fact that it is leaking by the backing plate only, is that I have the rear spacer in backwards behind the bearing. This is causing the leak between the backing plate and the swing axle.

All I could fine was in the Haynes book and it says the inner spacer the taper goes in . I assume this means toward the diff side. I didn't find how it goes in in the Bentley.

Also found on a search that the inner spacer taper faces the diff.

The chamfers of both the thick and thin spacers face toward the gearbox. Please see #5 & #10 on the diagram above.

"Hoping" you assembled the inner spacer correctly may be why this problem has been ongoing. You should pull that bearing and confirm it's orientation.
