Can you describe the knocking? The classic failing-axle-knock can be varied by weaving back and forth at highway speed (assuming this is a steady noise, not intermittent). When you weave to the right the car is loading up the left side axle, and so an increase in noise would indicate the left side axle is going bad, so that would be the axle to change.
If you simply are getting a knock due to irregularities in the road surface, that probably isn't the axle. I would always get a good used original axle over a "new" or rebuild, unless it was from the MB dealer. Everything else has a pretty crappy reputation. As long as the boots don't fail, the original axles usually last hundreds and hundreds of thousands of miles. ------------- Max Charleston SC On Fri, Jan 13, 2017 at 7:44 AM, Kyle Arola via Mercedes < mercedes@okiebenz.com> wrote: > I promise I am not just replacing just to replace them... hahaha!
