I had a quick look at it looked fine but I will take a closer look.
On a motorhome this steering is quite dangerous and you can't do anything but maximum best concentration to keep it between the lanes. Not very relaxing. I increased the rear air assisted suspension from 35psi to 70 and that feels bettter. it's just the steering now. I've not checked the pressures yet on those.
I know on the older type steering box you could tighten stuff up but this power steering rack I've no idea
