2006 is250 sport with ML driver side rear is lower than the rest of the car. Just the driver side rear end sits lower than the rest of the car. Car only has 38000 on it, car has been sitting for 5 months (wintered) inside heated garage. Babied, has not been driven hard. Has never made any noise ever.

 

Blown shocks?

 

Had the same issue except front and rear drivers side. Took it to an alignment shop he said bent lower control arm, that wasn't the issue. Next he said blown shocks, also not the issue. All I did to solve it was get coilovers and fixed it like that.

 

How were you sure these were not the issues?

 

Because I replaced both of those items and it didn't fix it.

 

Hmm I'll look into but my car has no miles on it so. I am skeptical.

 

I'd start with looking at a new shock. But before that, inspect for an odd damage underneath.
