I wouldnt JamesJ, over 12 months ago i booked in for the said job on good recommendation in the trade- The comments bring it back if it rattles its good for 100k.
This suggests they dont have the knowledge that even we have.
Incidently just caught it in time 3k later, Benny did it at short notice in Ettingshall.
Always weiry of garages, even people tried and trusted for years. 5 engine bolts missing on a Pinto engine the other 3 loose, only taken in for an half shaft bearing in Bushbury. Loads of similar stories even multinational conglomerates, if you want a job doing right either do it yourself or stand over the repairer.
