I have personally had the vehicle that I have the poly bearing installed on at well over 100 mph at charlotte motor speedway with this bearing in place and NO vibration, mass chaos or other catastrophic failures. I think that qualifies for a pretty good shake down of a part. Is the poly support needed, no, is it better than the Taiwan 25 dollar units yes. Andy I have had problem with the stock type replacements and they as pictures prove are not constructed like the originals and the mid joint on a two piece shaft is a big enough pain to take apart that I did not want to do it every two years. My 68 does not see much driving, but if given the option I would purchase the unit again. I offer this based on my experience with BOTH types of supports and this is a much better constructed unit than the cheaply made parts house replacements.

Well thank you. I have already bought the bearing and I plan to install it for just that reason peice of mind. I hope!
