Hi, we have a Reich 'Move Control' motor mover fitted to our single axle van. The mover was fitted new 2 years ago and sits in front of the wheels. At first it worked fine but after our second service the nearside wheel came off the van about half a mile from the dealer. The mover (and some of the van) was damaged. This was repaired by the dealer who we will never visit again. Unfortunately it seems that the mover is no longer quite as tight to the wheels and it slips when it comes under any stress such as level ramp or even the sloping kerb onto our drive. It used to cope easily. Finally the question - is the mover adjustable and if so, how?
