I took the Octoavia to Kwik-Fit this afternoon to get a new wheel and tire for the car. Everything was fine until they spun the wheel on this machine they have there. It was noticeably buckled. So we kept the spare wheel on until I could get a new wheel and put the car on the hoist to test the tracking. The guy doing this came and got me from the waiting room and showed me him wobbling the wheel back and forth, which basically made it impossible to fix the tracking as the wheel would just wobble back out of alignment again. Crap. There is obviously something wrong inside the wheel arch somewhere.
The manager at Kwik-Fit gave me the number of the nearest Skoda dealership, which I will take it to on Monday. I did get a new tire at the same time, so that is one less thing to worry about.
