I took my family van (Sienna) to the local Sears to figure out the problem w. the sensor on my tires. I knew the sudden wobble on my front left tire wasn't usual and I thought at most I needed a tire rebalance and alignment. I had a warranty on the tires and kept it serviced well, so it was obvious it was a tire problem- not bushings or rods or joints tied w. the steering. However, I got the run around by Sears saying they believed it had nothing to do w. the tire when Buddy South took a look at it for free (before I took it to Sears) and told me the belt on the inside of the tire was going loose, creating the wobble. I had the two front tires replaced by Walmart, w. Sears not honoring their contract. Buddy South was right in that it would take away the wobble. Next time I have a problem, I know they'll make the best recommendation for my vehicles and I will pay them for their honest work.
