Leaking Shock Absorbers

[Ed in Maine]

I have a set of original shock absorbers that were rebuilt by the previous owner. They look very nice and seem to have good action but two of them leak between the cover and locking ring where the cover contacts the o-ring.

Now I know this is not going to look like an original shock but after several days this shock has not leaked. I purchased a roll of Buna N rubber 1/2" x 10 ft. part no. 47400452 from MSC in Mableton, GA. The rubber has an adhesive to make it easier to put on and stay in place. I also used Permatex RTV Silicone Sealer and a 3 1/2 in. hose clamp. Dump out the hydraulic fluid and clean the outside of the shock with a solvent. Put a bead of RTV at the seam where the o-ring is located and gently put on the rubber strip cut to the correct length. Put the seam at the top. Following the Permatex instructions, wait an hour and then tighten the hose clamp. The repair costs about $20.00 and the materials purchased will do all four shocks. Good luck, Ed
