Bought two new tires for truck since was taking a long trip in a few days.
Found truck had very annoying shake from rear for entire trip so made appt to have checked. Jason advised that the left rear was only 1/4 oz out and right .5 oz and by the way your control arm bushing are bad. I watched the truck the whole time in and no one looked at the front end. Well the truck still shook so took it to another shop where they found both rears were out by .5 oz and now drives like it did before. Also had the control arms checked and there is no problem at all.
Goodyear either has a balance machine that needs calibration or they have someone that needs schooling .
I'll now stay with my local shop thanks !
