Probably one of the easiest ways to become familiar with the functioning of your Minuet's Dura-Torque Axle is to read the article referenced in the link below:
Dura Torque Axle
The Dura-Torque axles can and do wear out. The torsion arm should be pointing down -- anything level or pointing up indicates problems. Mine was about level, and the coach was riding quite rougly -- anything left unsecured in the coach would most likely find its way to the floor. My new axle was manufactured with the maximum down angle and a slight increase of capacity to, hopefully, slightly increase my coach's ground clearance (there was an increase of about an inch and one-half).
One of the challenges with my Minuet was getting hitch height low enough on my K2500 Suburban -- I have the deepest drop Reese draw-bar available and it is still just under an inch higher than would be ideal. Any amount of pitch to the rear increases the likelihood of problems with dragging the rear of the coach on steep drives.
Good luck with your Minuet!
