Jon, the fact the coach will lower doesn't really point to frozen suspension in my mind. That doesn't make sense that a bushing or radius arm would freeze in one direction of rotation.

If you put a pair of twenty ton bottle jacks under the rear hitch you can raise the coach without a tremendous effort. I would try to mechanically raise it before I took the suspension apart.

One thing is unclear to me. When you say it won't raise, can you define that it terms of how high the wheel well arch is above the tire?

Does the front raise on that side? Is the coach twisted when that happens?

I am assuming the coach is on level ground.

Give our love to Alie.
