Camber limits 95 E300D
 

Just had 4 wheel alignment at 100K
Tech reports that Ft Camber -0.5 R and -0.9 L are maxed
short of spec -0.2 to 0.2 both L and R

Is this a concern?
What must be done to permit the adjustment to be brought to spec?

A "Sportline" version of your car (gas model) runs -1.2 degrees, so LOTS of negative camber is potentially allowable.

The first thing I'd want to do is to set both sides alike, i.e. both at -.9 (ideally with me sitting in the car). Usual suspects to bring your car back to OE would be lower control arm bushings, ball joints & top strut mounts...they are the primary wear items (but 100k sounds a bit early-just get the freebie alignment re-check; tell them the car "pulls")
