Is your H2 like this?

Sounds like the drivers side torsion bar may need a turn or two. One full turn on the adjustment bolt equals approximately 1/4" ride height, up or down. The dealer can re-adjust the "Z" height and align if necessary or you can use a 3/4"or 18mm socket wrench and make the adjustment. One or two turns probably will bring it where it was originally. Always measure from the frame rails, body panels are not equal side-to-side. It helps to have 1/2 tank of fuel.

Several of the H2s I've checked, have very little room for adjustment and they're all different.Some have more adjustment travel on drivers side, and some have more adjustment available on passenager side. I ask the dealer why, but they don't have an answer.

Then again, the problem may be the rear suspension.
