Hello Jim and Fred,

Thank you both for responding. Sorry, for not replying sooner, was out of town.
Jim,
I did rotate the tires to see if it would make a difference, but, it still pulls. I think we should have marked the tires when we removed them. It could be they are on the opposite sides of the car now and have developed a tracking "memory".
Fred,
Thanks for the advise. The independent I used is familiar with MB's and has the tools. He doesn't work on a lot of them, but, has in the past. He was perplexed why the caster would not come into spec. I will discuss with the Stellarship my options.

If anyone else has any experience with setting caster problems on W124s I would appreciate your info.

Brian

For now, I think I will remount my old 15"s and see if there is a change.
