It's ok guys...lol. Will figure it out. Now I do not want to get in trouble for starting a rearend discussion in the general disscussion area. Is this ok here or should we move it to the drivetrain section?

You should never have to put a seal in the freezer to shrink it and it should have come back to original size ... anyway it needs to be pressfit and should not be that difficult to do.

The prep work is critical, all oil should be removed from the housings sealing surface...wipe it with lacquer thinner on a rag or brake cleaner in a rag.

What I do is use black silicone sealer on the outer parimeter of the seals press in surface...what this does is help take up any imperfections, nicks etc. from removal of the old seal. (STUFF HAPPENS I know...lol) Do NOT put it on the housing first or it will get push into the bearing area...NOT what we want.

SO now the hard part, how to get the seal in with a pinion shaft sticking out in the way. Well you could tap criss cross around until it is in flush with the edge of the casting. Do not recess the seal! You can use a big 3/4" socket set if you know a friend that might lend you the right size socket and extention...you must have patients to get that first initial seating of the seal in square. It is alittle tricky but everyone here that can turn a wrench should not have any trouble .

Another thing that could have happened ...maybe you lost the spring from behind the seal lip upon install and it is just laying in there behind the seal not keeping tention on the seal... check your next seal see if it has one if not then another reason might be - you just bent the seal metal enough to make the seal center out of round .

My suggestion is to find out exactly where it is leaking from on the seal. The rubber or the press in fit between the housing and the seal outer parimeter. Jim

If it is the outer parimeter then you know you need the sealant next time. If it is the seal around the yoke ...??? something when wrong with the install OR you just do not have theright seal...Maybe? It is hard to tell unless I am there. Do you have the part number or receipt.? Jim
