Hi, Just need a bit of advice. Took the car to Ford for a service, its a 2010 Focus, Zetec 1.6 thats done 55,000 miles. Was told the rear wheel alignment needed to be checked, as the gap from the tyre to the body on one side was more on one side than the other. Its not much, havent measured it, but it might be about 10mm difference. the car drives lovley, doesn't put to the side, stearing doesn't vibrate, no excessive tyre wear, they checked the tyre depths, and the rear tyres were 4.0 3.5 3.0 and 5.5 5.0 5.5 these tyres were on the car when I bought it 18 months ago, If I felt there was something wrong, I would have got it checked out, but I have had not cause to think the rear wheels have a problem, Are they trying to drum up buissnes or should I take it somewhere to get it checked. Is It 4 wheel lazer alignment I need, and any idea how much it will cost. Thanks for any replies.
