A couple of other peices of info if this helps. The drive does work(barely) not strong enough to go uphill. This happened all of a sudden. Went from working great to crap instantly. no visble fluid leaks.
All of a sudden my right side drive went out. Its creeps a little but it is useless. Creeps forward and backward. Hydro fluid was low but not empty. What would cause this. There seem to be no broken linkages and other hydralics work fine.
