Curious if anyone else has experiences (good or bad) with aftermarket replacements. The factory assemblies are quite pricy and I don't necessarily need something that will run another 70K miles, as I hope to be moving to an updated Vette before that. However, I bought one set of replacements from Mid-America and the bearings started howling after about 25K miles. Now, one of the two "no-name" replacements I bought to finish out the driving season has excessive play (after 2K miles!). Do I need to cough up for the OEM components (which are probably coming from China by now as well), or is there another good quality option?
