I apologize I am new to the forum and have not done a search yet but need some help. 2009 EXL with 32k miles. We had the tires replaced about a month [email protected] Sams Club, Goodyear Assurance. The car is my wifes but a week or so after getting the new tires I noticed a little shudder seemed to be around 45mph. I had her take it back for rebalance. Sure enough they said it needed balance. Then the next week I notice it pulling. Of course they don't do alignments so I have my wife swing by a Tires Plus. They report it is way out. This brings me to today. We are on are family vacation and hit the road bright and early this morning. First off the wheel is not centered but I can live with that. However the shudder is there and seems even worse. No real sign of a pull. Well I cannot take it and decide to reroute and land at a Sams club for lunch to get it looked at. After an hour wait they rebalance and said it was off a little. Well this makes no difference. Now I am halfway to my relaxing vacation with this driving me crazy. So it is really bad above say 40 and actually calms a little above 75. What is left? Warped rotors? I read some things about the tranny, torque converter and some software updates. Any help would be appreciated. 1300 more miles of thus and I may never have feeling in my arms again.
