No one seems to have the entire arm assy listed. Both MBShop and ******** list an "Idler Arm Repair Kit" (pic below) for like $20. That's where I came up with the "rebuild" term from.

Do you agree with my asessment then Lee ? Sounds like an idler arm issue? I was just driving it a few mins ago and it was acting up again. This morning it was fine on the way in. I did notice that it is worse on highly crowned roads than on flatter roads. It also does not seem to be speed dependant.
