Anybody have any problems with the trailer jack , I have a 2019 zx225 Skeeter trailer and they have the Fulton F2 trailer jack on her and last year when I took in for service I asked them to check it out didn't seem right when jacking up to take off hitch (grinding) I guest they checked it out ?? But now the other day seemed like really grinding a gear does these have to be greased some how see no grease fittings ???
