Been trying to track down a clunk from the driver front end. Car is a 74 with Koni adjustable insert/shocks on all 4 corners. Looks like its coming from the shock on driver side at the top. Something is loose inside the shock tube and/or cover which duplicates what I hear/feel while driving. I checked everything else on the arms/rack/torsion bars/ball joint and everything tight (since I just also recently replaced all bushings etc). So I wanted to remove the shock to take a look but could not remove the nut after loosening it (while countering with a pipe wrench). I suspect the tab washer (which usually locks the nut and prevent it from spinning) broke. I have read that maybe a impact wrench (I have a cordless and corded impact but not air impact wrench) may spin it loose but may also damage the shock internals so I have not tried that route? Any other ideas on how to remove the nut?

I use an impact wrench to remove. Takes two seconds and no shock damage. I was told to do it that way by a long time Porsche tech.

It’s not on super tight so any cordless should work fine.

Clunks are usually from the large strut top nut under the large dust cap/metal cylinder coming loose. A pipe wrench will tighten it down.

I had this happen on two different 914s. Put a small dab of locktite red on the threads of the strut top nut when reassembling.
