Is this normal? Got a set of new shock assemblies for my f150 (motorcraft) from rock auto. Noticed 1 had a fluid line down the side. Appeared like 1 drop ran down. Above the fluid line by the steel ring there is a very slight pool (looks like a drop where the steel ring meets the shock body, couldn't get a Pic with the spring in the way). Otherwise it doesn't seem to be actively leaking. Just that 1 streak. Is this just weepage of a new shock? Or send it back? Don't want to mount it without confidence, then the return through rock auto would be tougher.
