I have a 2005 Estate 2.0D which went for a 4 wheel alignment after I hit a pothole and ruined 2 tyres. The alignment at the rear nearside was way out and in carrying out the adjustment to correct it the garage was unable to fully complete the task. There was no more adjustment available. On the offside there was just enough adjustment available to get it within limits but no more. What do I need to replace to get some adjustment back? The garage did talk about forcing the rear wheels together at the bottom to get that adjustment back, but I would rather get the right parts installed. Any idea what is required to achieve this? Thanks in advance. Alan.
