Truck Tech,

There is no torsion arm on this steering box. It's direct hydrualic. Nothing but hoses from the box to the cylinder.

That's why I wasn't sure on what was causing this wander problem. Some strange hydrualic bypass problem in the cylinder. If that was the case then I would just use a reman instead of repacking the original cylinder.

As for the cylinder itself, I believe that this one isn't a sealed unit. I believe that it has a "C" clip that holds the gland seal packing at the end of the cylinder.
