2007 GL450 unstable in bumps in high speed
I have a GL450 2007 with almost 120,000 miles on it. Every time I go over a bump at speeds higher than 50 mph car feels really unstable and I feel I am losing control on steering. Any ideas of what's going on

I also checked the body height from fender to ground on all sides, they are uneven, reading between 31 and 34 inches, is this normal?

OK, that was the read in the morning, right after starting the engine and raising the airmatic completely and bringing it back down, they are even again, measuring 34 inches from the gound

Better way to measure would be from the fender lip to the center of the wheel.

Ok, really dumb question, but have you ruled out shocks and tires?

Bad shocks / struts would cause chopping in tires..and not necessary affect toe. Would cause noise / vibration later if tire worn badly.

tires were brand new last year and have 15000 miles on them now, they still look brand new, haven't measured the thread though.
