The re-man units from the el-cheapo auto parts stores are junk, being rebuilt by people overseas who dont really know the details/importance of what they are doing and why. Please look around your local area or a little farther out, and find a gear shop that has the expertise to do a quality rebuild. In many cases they will even do the remove and re-install for a modest additional cost. The many guys I know that have done it locally have never had issues, they come back like new because they were rebuilt using a quality kit and knowledgeable practices. Good luck!
