Upper Tubular Control Arm Problems

I am pulling the CAP AUTO/MANCINI Upper Control arms Off! The old ones will go back on after I clean them up. Cap Auto jerked me around for a full year and their only advice made things worse! My recamendation to all who read this, unless you want to waist a huge amount of money and time on these control arms and are willing to put up with unbelievable squeeking noise, then go ahead and buy them. They are not for me!!! Tom
