Oil In The Front Struts?

Post by cuthbertdavies »

I'm in the process of rebuilding my front struts with new shocks, although it might be a bit redundant since the ones I removed appear to be in new condition!

Upon removing the shocks, I noticed there was oil in the tubes. While I've encountered this in other cars before, I'm uncertain of the reason behind it. I don't think it's due to leaking shocks; rather, I suspect it serves a purpose, perhaps to help cool the shock?

Does anyone happen to know the viscosity of the oil and the recommended volume?

It was for the technology in the eighties, Bilstein etc nowadays advice to not use oil.

Bilstein writes this in the mounting instructions:
Remove all internal parts and oil from strut.
