So after a good swamp ride two weeks ago I finally got to fixing my XMR. The belt exploded on me causing me to tow it home. Installed replacement belt last night no prob. Buuuuut found oil leaking out of the rear "main seal"? This is where the rear drive shaft enters the motor. Fairly good leak, need to find this seal. Can seem to identify it online. Seems to be fairly common. Anyone know p/n or link ? Help is appreaciated.

I looked at it last night. Its just in front of a 4 bolt flange at the front of the rear drive shaft. Seems to be sealing from rear of motor ?

You will want some black RTV too. The plate is sealed (more like glued) to the gear box. When doing this make sure to clean the gearbox very well and use only enough to cover the area. If you use too much it will spill into the output bearings, no good. This isn't a rear differential cover on a 1978 camaro it only needs a little as the machining is much more precise.

How difficult is it to replace ? Pull the shaft? Just loosen the rear diff up and shocks/axels ?
