Update: Thanks for comments. In the end I had no choice but to let the local Kwik Fit do the work. No other garage offered to do the work in time for me to drive the 220 miles home. I can see that Kwit Fit doesn’t have a good rep on here. I have never used them before. Here was my experience.
1. They put the van on a ramp straight away and found the full extent of the problem.
2. They gave a quote range based on best the worse case scenario.
3. They carried out the work in the specified time scale. They found that the tracking rod also needed repairs. They repaired this within the original quote.
4. Full tracking and a laser report on how the shocks sit comparison to each other. Advised to call into my local KF for a final included check after everything settles to ensure everything is ok.
Drove 40 mile yesterday and all seems good
Maybe I have been lucky. The Christchurch East team seem to be on the ball.
