Changed the coupler, new coupler came with new yoke with o ring groove. I figured I would change both u joints unless It's a total pain in the rear. Anybody ever try changing these without pulling the shaft out? I have the tools spanner wrench etc. I changed all the seals, o rings and gaskets a few years ago in the drive because it wouldn't holding pressure, but I never broke down the drive gear and bearing assembly. Looking for the easiest way out. Any suggestions? Thanks in advance for any feedback.
