So the rear passenger shock on my ML350 is leaking. In fact, I suspect it has been so for almost a year (been hearing loud BANGs from that corner when riding off-road). The shock is covered in "mushroom"-looking junk, whereas the other shock is clean.
Would you guys suggest replacing both rear shocks at the same time? Or all four corners? Anything else worth replacing down there? Perhaps a full suspension refresh? I'm on air suspension. Car has 120k km / 74k miles on it, and I believe it's on all original components.
