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 ....
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.I have changed the rear seal twice to no avail .

Axle seal THere's a seal a few inches into the housing and another seal by the bearing

Boy I guess. I didn't see "nut and washer"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.
pinionAre we talking a pinion or axle seal leak?
I disagree, many of the diffs i have had apart have sealant on the splines,a rubber waser/insertI would suspect, regardless of the seal location (but from OPs description I suspect pinion is location in question ) there are only a handful of reasons for a leak
The spline should never get oil to it if the seal is good.
- Seal surface is grooved or damaged is some way.
- the seal is installed incorrectly
- the seal is not correct for the application
MY mistake, I was thinking the sealing surface was on the pinion shaft, forgot it was on the yoke.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.
that was my thought also.Time for a speedy sleeve?
This is the first thing i thought of.Time for a speedy sleeve?
This is the first thing i thought of.
The pinion yoke probably has a groove in it where the seal rides.
Hmmm.He said it's leaking down the splines and around the nut.
This is how people get surgery in the wrong places.
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.

Hmmm.
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........
