The slip yoke is covered. Im just going to grease the u joints only and leave everything else alone. Dont want to disassemble anything.I just did mine too. Curious if yours has the Zerk fitting for the slip yoke. My 02 Sequoia does not. I'm conflicted on whether I should bother to disassemble and regrease the splines. I'm not having the clunking issue, so why borrow trouble?
