: Slight amount of oily residue on the rear struts

I have MRC, F55 Magnaride, and the guy at the alignment shop was telling me they were leaking. He did ask if I hear a clunk over sharp bumps from the rear...I do but it's worse on "performance". Also, the damping is quite poor at speed bump speed, even on "performance". Is this a sure sign replacement is on the relatively-near horizon?

If so, I'll start scouring local junkyards for STS's with Magnaride, for both front & rear struts, just in case.

I don't think I want to know what these cost, new, from a dealer. Plus, the car has 'only' 90K miles on it. I hope to keep it past 200K, so I'd be, in theory, looking at a second set at some point.


One thing I planned on doing was wiping a bit off with my finger, and seeing if it has any magnetic properties. I'm unsure if this is a valid test, but if there's one place oily residue exists, it's roads.
