I have a 2007 S60 which is driving me nuts because the wheels won't stay balanced. Any ideas as to the cause will be appreciated.
The car was riding fine for a half year or so until I took it in for the 30,000 mile maintenance. They rotated the tires, balanced the wheels and aligned all wheels. About a week later, I started noticing some vibration which got increasingly worse. I hadn't hit any significant bumps on the road in this time.
After a week of this, I took it to my local Goodyear shop. I've dealt with them for years and the guys are top notch mechanics. They found that the front two wheels were slightly out of balance so they re- balanced them. They thought that maybe the wheel weights shifted or something.
Everything seemed fine but after a week of smooth riding, it's vibrating again, minor at first then getting worse. I'll take it back to the repair shop and ask them to road test it but I'm getting tired of having the balance checked every couple of weeks.
