I have changed the rear seal twice to no avail . Grease appears to be coming out (weeping) from the splines , leaking from behind the nut and washer . Is there a cure or are the splines wore allowing this ??? Thanks It's drivable but annoying ....
8 3/4 grease leak .

Are we talking a pinion or axle seal leak?
Pinion leak. A small bead of sealant usually keeps it in,can put it in yoke where splines end at the top,or under/around washer. I usually grease the spline, thats enough to keep it in for a while.
If you put silicone on the splined shaft before yoke goes on, you will need a puller to get it apart.
Check your vent as well.
And fill to 1” below plug. Running it rim full isnt necessary. If you look up fluid capacities,it will tell you how much it should have.

Not awake yet eh?
To the OP, like mentioned you can use sealer under the washer.
Just fill the gap between the splines and washer completely with RTV.
You will want to solvent wash it first so the RTV can stick to the metal.
Boy I guess. I didn't see "nut and washer"Not awake yet eh?

Time for a speedy sleeve?
pinion
I disagree, many of the diffs i have had apart have sealant on the splines,a rubber waser/insert
Or a rubber coated washer that seals spline. Service manual will specify the method of sealing.
MY mistake, I was thinking the sealing surface was on the pinion shaft, forgot it was on the yoke.
slapping forehead!
I deleted my post to not spread false info more than I did!

This is the first thing i thought of.
The pinion yoke probably has a groove in it where the seal rides.

He said it's leaking down the splines and around the nut.
This is how people get surgery in the wrong places.

Hmmm.He said it's leaking down the splines and around the nut.

Then a new seal won't do it then.
Honestly, i've never seen one leak through the splines and past the washer and nut before if everything is tight.
And if the nut isn't tight, then the yoke would wobble and wreck the seal anyway.
Pictures would go a long way here........
THen he needs to put some silicone on the splines. Never heard of that happening. I wonder how sloppy the yoke is on the pinion splines?He said it's leaking down the splines and around the nut.

It happens, just like a balancer can seep oil through the crank snout.
Still, checking the nut first would be a good move.

I've ran across a few that leaked like that and as mentioned earlier some RTV on the splines should fix you up.
