The subject car is a 1989 560SEL, 171,000 miles. Car was wearing front times on the outer edges, and new Michelin Pilots were mounted and balanced, and I took the car in for an alignment.

Initial alignment readings showed out of specification on the passenger side camber/caster. Mechanic installed the bar to provide pre load on the toe setting, adjusted eccentrics and threaded rod at reaction joint. Final settings were in specification, except for 0.5 degree delta was 0.6. Mechanic had a difficult time, as "this is the first Mercedes I ever aligned"

About 60 miles later, (next day), I noticed the steering wheel was turned to the left when I was driving straight ahead. As I continued, this became worse. I drove back to the shop and asked them to take a look. I believed something must not have been tightened properly.

Car was placed back on alignment rack. Suddenly, the car "could not be aligned. Has this car been in a wreck?" Other statement of "the whole cradle must have shifted" I reminded them the car was in only the day before, and no visible damage on the suspension or anywhere else. I was told to wait in the customer waiting area and not watch the work, (as I had done the day before.)

After two short hours, I was told the suspension was "fully adjusted", and the car was "barely in spec" I was shown the passenger side adjustment at the braking reaction joint was tightened all the way to the nut, and both eccentrics were adjusted "fully out" I asked why there were "new" painted American standard thread bolts in the threaded adjusting sleeves, and why the nuts holding the reaction joint ball joints in the housing were all marked as if they had been tightened, and noticed the "vise grip" marks all over the threaded adjusting sleeves.

Any ideas? The car does track straight down the road, and no pulling or other drivability issues are present. Should I take another shot at a different alignment shop? Thanks for the advice.
