There is no special tool needed..just remove the back cover and use a large Socket, be very easy with it and pop it in evenly and flush..

Yeah like merv said you don't need a special tool I've never used one and had no problems

GM recommends using a small amount of engine oil on the outside face of the seal and the corresponding piece on the block. Do NOT lube any other side, particularly the area that comes in contact w/ the crank.

When you buy a new seal from GM, the instruction comes with it. If you have the tool, it's a 2 min job to install it. If you don't, just be very careful and make sure it goes on straight.

I read from the instructions included w/ the part. It's a lot more detailed than what I posted, I'm gonna see if I can find it online.

The idea that the crank to seal surface must be 100% devoid of oil. They recommend using it on the OUTSIDE of the seal and INSIDE of the mating surface for ease of installation. Some people even use RTV on the edges but there's no mention of that in the GM instructions.

My biggest worry is to make sure it goes in straight. Using the old seal or a block of wood should help with this.

interesting, i'd love to see the instructions. mine only came with a sheet of paper that says to install this new version the right way and has a "this side out" stamped on the seal.

i do notice that the inside of the seal, in between that plastic ring there is some lube.

This is from GM service inforamtion.

Installation Procedure
Important:

• Do not lubricate the oil seal inside diameter (ID) of the crankshaft surface.

• Do not reuse the crankshaft rear oil seal.

• Lubricate the outside diameter (OD) of the oil seal with clean engine oil.
Do not allow oil or other lubricants to contact the seal surface.

• Lubricate the rear cover oil seal bore with clean engine oil.
DO NOT allow oil or other lubricants to contact the crankshaft surface.

I wonder why the seal already has lube on the inside

I am not sure about the lube but as far as installation goes a piece of PVC pipe with the correct inside diameter makes the job a snap and is a helluva lot cheaper than 300 bucks

Yea I've noticed that aswell..on that little white piece of plastic that comes with it. I think it's probably to keep the Rubber from drying out.

That's about how much I put on when I said that I lube it..just enough to see that you put something there. I've never had any problems.

I've always spread some Oil around the outside of it too before I put it in the Cover..pretty much did exactly what the instructions are talking about.

so you put the seal on the pipe, line it up with the crank, then push it on?

yeah it does make sense to put just a little so nothing gets caught up pushing it on.

Most of the GM seals come with lube on the inside of the seal. This is so when the seal is being installed, the lip doesn't get caught and flips over on a dry shaft.

Am I missing the boat? I see about a dozen posts on here about how to replace the rear main seal correctly, but after reading the OP's first post he say he has "THERE WAS OIL ON THE FLYWHEEL BOLTS BUT NO SIGNS OF OIL LEAKING FROM THE REAR MAIN SEAL" I assume you all know that the flywheel bolt holes are not blind and the manual says to use their G.M. thread sealant with loctite if you dont use the sealant you will have oil seepage through the flywheel bolt holes and on the threads of the bolts and eventually it will seep some motor oil. So the question is Op is that the case or is it the rear main? The reason I say this is because if the rear main is OK you dont want to mess with it, as stated earlier sometimes it will start to leak or leak worse from an improper install.
