you need to become THOR here...

grab your hammer and a 3/8" 6" extension. use the small part of the extension as a chisel and put that on the flat star part in the cv joint.. start hammering away till the flat star part slides over the c clip.

lol.. remember, there's ALOT of hammering to be done!

btw.. get a 2x4x24 board ready for hammering everything back together!
