Hi everyone. I found this website this morning and thanks to you I have saved myself £££££££££ 's in garage bills.I was having the same problem with juddering once I got to 50mph.Had one front tyre replaced this morning as it had a split in it and thought maybe that was the problem. BUT on the way home the problem cont,came on here and read some of the posts.Hence I took my car back to get the tracking checked. When the other front tyre was taken off it was found that the inside had blowen in several places......... B*** pot holes and sports tyres!!!! Now the car drives like a dream again.........just as I was toning up my arms muscles lol:clown:
