Most likely you have the Venture Manufacturing Landing Legs assuming you don't have hydraulic driven legs. Replacement pieces parts including completet legs are available. The legs are easy to work on assuming a modicum of DIY skills. Their web site has mess of PDFs relating to the legs including how to disassemble and rebuild them. Give them a call as they are easy to deal with.

I have a collection of the PDFs that I offered to many members in the past. PM me your email address and I will send them to you
