Vintage Cars: mercedes126 380se......suspension, pneumatic suspension, hydro pneumatic

Question
Hi....my Mercedes has a lean at the rear....about 1 inch difference....i have hydro pneumatic suspension....there are no leaks at the rear shockers or accumulators.....i have even changed the shocker and accumulator from side to side and the lean is still there....the tyres and wheels are matching....any ideas?.....thank you  Rhonda.

Answer
Rhonda, my first guess would be subframe bushings.  The unibody sits on top of the frame via attachemets that have rubber bushings in them, perhpas one is worn, the other possibily, but very rare would be a bent frame/body.  Has it ever been in a colision?
Good Luck and happy Motoring
