I had one of the jacks fall apart when the truck was sitting in my driveway. Looked up on internet and found that older versions have failed quite often. Called Reco and was told that it couldn't be repaired and had to be replaced. Not being a great mechanic, I purchased the replacement. Once I received the part I took the broken one off and looked it over. I believe it could be repaired and will try to do so if any of the other three fall apart.
This is the inner tube assembly:
This is the area at the top of the assembly:
This is the screw mechanism:
Hope this is some help.
