I notieced a bit of harshness/banging in the front end of the 300SD, so I had it checked.
The Tech report says "right idler arm bushing bad, steering damper marginal, right lower ball joint boot bad." They also recommend AC and PS belt replacement. I'm planning/budgeting for these parts soon.
I also got rid of a lot of harshness in the Audi by having rear bushings replaced. The techs said these are don't usually wear out, but they did, and I replaced them, and it's a new car again!
It might not be the shocks, there may be something else. Have it checked by the techs, it's money well spent.
