I have a slight wobble to the output shaft and the seal is leaking. How difficult is it to replace the bushing? Just replaced the tailshaft bushing and seal this evening. The local NAPA carried a seal and bushing kit for $12. ~3 hrs but I'm slow and detailed. The bushing was badly damaged by previous mechanics and a bit worn. The driveshaft still has a very slight wobble on the output shaft but I think it's as good as I care to make it now.
