The top of the front springs sit into a notch on the upper control arm. If one of the springs isn't sitting into this notch, it will raise that side of the car. It also causes the opposite side rear of the car to push down a bit too. The spring on the"high" side may also be installed upside down, this will also cause a lean.
bad shocks or broken springs on one side, or u weigh alot
Two things that could cause the rig to lean to one side or the other could be:Broken shocks or springsUneven load
Check your shocks
Replace the shocks and struts! :-D
The lever on the side is there to lift the seat forward.
Check your springs and air bags.
4 inches is a substantial amount. I would suspect broken springs.

Weak or broken springs or torsion bar.
A right-side lean in your E350 could be due to several factors, including uneven weight distribution, worn suspension components such as springs or shocks, or a flat tire. It's also possible that there could be an issue with the chassis or frame. To accurately diagnose the problem, it's best to have a professional mechanic inspect the vehicle. Regular maintenance and checks can help prevent such issues from developing.
