I am in the process of rebuilding a blown engine, (warped head) that I bought in order to get a good transmission and noticed that there was some evidence of oil leakage at the cv joint next to the transmission' so I removed the axle and seal to see if I could find some numbers on the seal that might correlate to something available locally. Guess what.....Car quest has a seal, #223540 , that is an exact replacement. They could not cross reference the numbers, but by taking measurements of the original they found an exact replacement. Don't know what it was originally meant for, but If you go to a car quest outlet and ask for it by that number, you'll get it. By the way, anything I found on line was at least $25....It's $9.00 at car quest. Replacement is pretty straightforward. First, you'll have to remove the axle/cv assembly....It's just held in by a snap ring on the end of the shaft. I just bumped the joint housing with a big hammer and it popped out. Using some sort of wedge would probably work too. To get the old seal out, I used a slide hammer with a very heavy washer with a diameter just large enough to fit thru the seal. Hook it behind the seal and tap it out, moving around the perimeter in several places to be sure it doesn't get cocked and mess up the hole. To get the new one in, yoou'll need a piece of heavy wall pipe with an ID of 1 3/4 inches. I started to use an old bearing race, but soon realized that I needed something longer in order to "aim" it properly and keep it straight as I started it in....something at least a couple of inches long. Before you start, take a good look at the old seal to see how deep it was seated and seat the new one accordingly. Mine was easy to do because the motor and transmission assembly was out of the car and easy to get at. If you're doing it with the engine in place, there will be some other considerations you'll have to address which I won't go into here.
