The shaft should have been cleaned then a sealant applied in the groove. As the new sleeve was installed centered over the groove it would push the excess off, and the excess should be removed. Then trim the push ring off.  Put tape around the edge of the sleeve to protect the seal lip be sure to but a lube on both the tape and seal and then install the seal.
If you need a new seal and sleeve I have access to these things thru work where I can get you a really good discount, if you can wait for me to get it out of our warehouse and ship it to you. I will check my pricing if you would like maybe I can save you some money.
As Moose mentioned, I have seen the RTV applied to the splines to keep oil from seeping thru them.  Again everything needs to be really clean with no oily residue present when applying the sealant.

I got the recommended oil and a new seal and you think I should put another sleeve on?  That one is on tight, but a I said I did not trim off the push ring.

If so, how will it come off?

I cant tell you if the #2 Permatex was the correct sealant to use at this time. If you can wait until tomorrow night I will give my Permatex rep. a call and ask if it was ok to use it in this application.
The sleeve should have fit tight, it will actually stretch its self around the shaft as you drive it on. The sealant is used to fill the void and to stop any lube from seeping thru between the sleeve and shaft. As far a removing the push ring if it is not in the way of anything and does not rub on the seal it does not have to be removed, if you noticed before installing the sleeve there was a groove around it and that is to aid in the removal of the push ring.
One other question did you put the recommended amount of oil in the rear end?

Be careful on posi fluid, most brands say for top off only. The posi won't work for beans with it. And leaking at the seal on those old diffs, we have one in the dragster, can be caused by fluid coming past the splines and out around the nut. Leak like crazy they do. Can't get the old lead paste any more so use a really good rtv like The Right Stuff or Ultra Black or Dow Corning 739 (the best) will stop the leak.

Seal the pinion to flange splines well with a good RTV like Ultra Black or the Right Stuff, too. The dragster we have has an old GM diff and it was pouring oil out that looked like the seal but it was actually coming by the splines.

I have read much about putting sealant on the spline gears and I certainly did not do that, nor did I put any around the sides of the pinion seal.  Thanks 62131, I will wait to head about the #2 Permatex.  Cool53, I am going to coat those gears.

Tomorrow I plan to take it back down and clean everything really well, deal with the ring if necessary, add the recommended tape on the ring to protect the seal (any particular kind?), install and hope for the best.

Oh, I filled the rear end until it started to come out, then put the plug in.

I checked with the Permatex rep today he said there should be no reason for it not seal just as long as you put enough in and around the groove so that when you installed the sleeve the groove was completely filled.
As far as the type of tape I always use electrical tape as it will stretch a little and you can get it tight around the shaft. To remove the push ring you can take a pair of diagonal pliers and snip the push ring and  it will tear off very easy.   

I'm in the middle of replacing axle bearings, seals and all the brake hardware in my rear end now, My frame is at the sand blaster getting cleaned up. I thought I would go ahead and get the rear end ready to install and found the seal on the passenger side was bad. So since I had to remove the axle I figured why not replace the bearings. I'm using a rear end out of a 85 Monte Carlo.

Thanks, I just took the yoke back off and the leak trail comes from the center of the seal and not from the sides.  I have a new seal if you think it needs replacing or just go with the clean up and sealant on the gears?.

Are you calling the splines the gears?
If so I would try the clean up on the splines or gears and try the sealant there, if you are sure you didn't nick the lip of the seal.

Just wanted to let everyone know that I followed your suggestions and we will wait and see.  I did get confused about the crush sleeve I was told about and thought mine did not have one, but the attached diagram showed me where it was located.

On a single traction rear end is it normal to experience a small delay and thump when turning the rear wheel from one direction to the other?

Maybe the second time is a charm.  It has been a week now and no leak so far.  I even took it on a short test drive this weekend.

Thanks all.

I took all the advice and cleaned it very well and used plenty of RTV on the spline gears.
