Yep, just replace both of them.

I believe I wrote-up the procedure, but if you're not comfortable have someone who's done it MANY times, do the install.

If done correctly, you don't have to remove the entire rear-hatch (do one side at a time).

Also, use ONLY Mercedes OE parts, not OEM parts (e.g., FEBI/Bilstein).

I tried OEM, and had to replace them 2-years later.
