Got a couple more Toyo Proxes Plus 4 tires and put them on the rear and had fronts that are at 8/32 rebalanced. All balanced fine. Road force looks good. The older tires were fine on the front but after spending 7K on rear had a shake when moved to front. Took the car back a couple of days later and they rebalanced all 4 on another Hunter machine after doing a calibration and they still show perfect??? So I said lets do something different and put the new ones up front. Almost good but a little movement still in the steering wheel. Went home and removed front rotors and cleaned hubs and both sides of rotor hat and back of wheel with wire brush in a drill. Again better but still there a little. Sometimes it shakes and other times its smooth. Checked for a loose tie rod they are still nice and tight. Car has 38 K on it.. Any suggestions on what I could look for?? This is driving me Nuts Err.
