I have a 2010 ford explorer sport trac Adrenalin, I have had to replace my R&P 3 time with in the past 4 years and its always the same problem. A vibration or excessive wear or slopy steering or a clunk from the R&P, can anyone help me with this problem or steer me in the right direction as far as why? 2 of the R&P was a remand ford and this one in now is a NAPA, all replaced by a tech at NAPA and alignment was performed with no improvement also I am expecting this one is ready to fail due to the charter when I turn. PLEASE HELP form the EXPECT OUT THERE! can this be s problem with only the remand products or can anyone recommend a best parts solution! Thank you and eagerly waiting for your reply!
