The EQ Leveling Jacks should not be moving side to side or front to back.
I would recommend that you download the installation instructions and check the torque settings for the jacks. Something does not seem correct if the jacks are moving.

Per the EQ Leveler documentation: the front jacks use a bracket that attaches to the Sprinter frame (i.e. box mount with box bolt). Plus it uses a bracket to attach the jack to the box mount. The "box bolt" is set at a torque of 140 lb. ft. while the "bracket bolts" are set at 75 lb. ft.
The rear jacks mounting mechanism uses a different set up so the torque settings are less as it relates the the Sprinter frame mounting bracket (i.e. 50 lb. ft.). The torque setting for the jack to frame bracket is the same as the front jacks (i.e. 75 lb. ft.).
I had loose bolts on my LTV Unity. Even though I have changed to a Renegade Vienna, I still check the torque settings at least once per season. This is also a good time to check the fluid levels of the reservoir.
