I have my knee action suspension working to a fashion,most leaks stopped if not completely ...the left side I just loosened set screw on big packing nut and tightened ..right side I loosened set screw and big nut,on other side prided off end cap ,next carefully remove shocks they are under spring pressure,use 3" long bolts to remove slowly,once off clean and inspect,my shock valves were the same, but best practice is put then back in the same shock and in the same location,once off remove set screw inside on main shaft be careful not to strip screw head,get a large quality made screw driver to do this work..not easy ! ..once set screw out use brass drift and drive out shaft about3/4" enough to get some 1/8" graphite rope and push into large cap nut,then pound shaft back in and put large screw cap back on..be careful about the 42 needle bearings they will fly out on the floor when pounding on shaft,put tape over shock holes fill with light oil and watch for 1 or 2 days for leaks,if all OK then put set screw back in shaft has to be in perfect alignment before set screw will go back in..then put end cap back on ,,install shocks in proper place using 3" long bolts and tighten each slowly to shock seat.BTW make new gaskets for shocks while you have them out..I drove car briefly and all seamed to work OK..email me if you have questions bigpine@zoho.com PS I'm not an real expert on this subject but been fooling on old machines for 50 +-...Spencer
