Does anyone know of a proper tool to install the rear main seal in a 22RE? The biggest diameter in my kit is only about 3 1/8 Ø. The Toyota seal is almost 4" Ø. Any suggestions?

 

I had nothing to use to install my last rear main seal. Make sure it's oiled and then take a clean piece of 2x4, lay it across the seal broad side down, and gently tap with a rubber mallet going top to bottom in an even circular path until it's in. Worked for me.

i jsut used wood and a hammer never had a problem replaced a many of rear seals over the years

 

The first one I did got kinked so now I'll try again. I used a driver that was way too small in diameter and I tried to drive it in like an outer bearing race. My mistake. As soon I get parts dinosaur to send me another I'll try a different method.
