the seal is worn, take off the drive shaft, remove the seal on the trans and replace. check fluid level after all is reinstalled.

yeah we took the housing off and couldnt figure out how to get sleeve off to replace oring, although, the oring from what i could see looked good, no nicks or tears. i replaced the shaft seal and the bushing. will sealing the hole on the yoke cause any problems?
and can someone tell me how to take off the sleeve to replace oring?

thanks

You dont remove the sleeve to replace the O-ring. Pull O-ring out with a hook shaped pointed scribe tool. Replace with new O-ring
