Fix the known problem first. Very difficult for it not to jerk if the dampeners are shot.
Air will show in the oil. Make sure the arms, on pumps are tight. Make sure the hubs aren't loose
on the wheel motors. Those 3 (dampeners, arms and hubs) items, have to be checked first before any hydro diagnosis can be done.
