Just got my car back from an indie tech (Sterling Star Automotive) and he informs me that the repeated clunking that has been emanating from the drivers side front ever since American Service Center (ASC) replaced my sway bar bushings and linkage bushings is because they failed to tighten the linkage up but rather just left it loose.
If you are paying what ASC charges (arm & leg), then they had better do the job right. Instead I received hackery.

GP at Sterling Star tightened up for free (even though he wasn't the one who hosed it up) and was very helpful and informative and didn't cost anywhere near what ASC charges.
