Bilstein Strut insert Q's

[franklinstower]

I have one strut that appears to be leaking on my '78sc.

I have a pair of used replacement struts - however, there are no markings on the struts or part numbers, so I was wondering if any could help identify these.



and secondly, they compress to different lengths? one compresses down to about 1.5" of the shaft remaining exposed, the other leaves about 4" exposed?



They both seem to have about the same pressure. Any reason not to use these?

Thanks,
Paul

I'll play devils advocate and say that for your time and effort and the relatively low cost of new inserts, I'd question the wisdom of using used parts here.

Especially now that you have an issue with one of them though I am no expert. Just been doing a lot of research on this job and parts lately as I want to get it done myself.

I see that you are local too! Let me know how you rate the difficulty of putting them in.

In my experience, a Bilstein insert that won't compress all the way is low on oil, and the floating piston that separates the gas and oil has moved and is interfering with the travel. If so, it needs to be replaced or rebuilt.

Ok, thanks for the info Arne2.

Shouldn't all bilsteins have a part number stamped? I'm still curious about the lack of any identifying marks.
