Just used the seal
Staff Reviewer -
Whenever I replace a bearing or bushing I do all related parts as well. This seal would not work if the bushing was worn but in this case I did not wish to remove the tail shaft of the transmission. I will keep an eye on the seal for leakage and if it drips that I will go for the bushing too. If it not broken I won't fix it. After I installed the seal and inserted the yoke I checked for excessive movement and was satisfied that is was not in excess so all should be well. This was installed in a 1964 Chevelle with 87000 miles on 8/2014 replacing the original factory seal. Let's see how the new one does.
Bottom Line Yes, I would recommend to a friend
