If your Sway-Bar system has 200k miles... I wouldn't even check them... I'd just REPLACE, especially given your Symptoms.Good point. The LCA bushings were rotten as they were original with 200k. I'll check these. Thanks.
At least on the W210, "Checking" was not always accurate. I had symptoms classic for sway bar Bushing/Link problem, but they "Looked" OK. Upon Changing? Symptoms Resolved.
