Thanks for the info:duh:I was beating on it for about 45 minutes with a piece of pipe but could not get enough behind it. someone said to use a pickle fork :hail:so I will give this a shot.You can try prying with a crowbar, but the long brass drift punch at a slight angle is the recommended tool. Oh, yeah, and a 3 pound hand sledge. Don't ignore the power of a BFH.
Brass is so you don't destroy the tripot housing. If you're changing the entire shaft, not just working on the seal, you don't care so much about damage. Use a 18" length of rebar. Often, the splines get rusty and stick horribly. One side on mine snapped right out on the second hit. The other side took 20 minutes and three beers.
It is a c-clip at the end of the shaft that's retaining it. Oh, I guess you aren't replacing it if you haven't bought a replacement to see the structure.
