Steering wheel action "slow"
 

I've had whats best described as slow power steering since I bought my 190e, its something I've always been aware of but not got round to looking at. All the parts in the steering chain except the pitman arm and stering box, have been renewed in the last year so is the box the issue? One symptom is that when exiting a corner/turn the wheel does'nt centre itself if I let go, it'll only go part the way back.

Is the box to adjustment too tight or do I have worn seals?

Mike.
