I've noticed there is a bit of play in my tongue jack but have not investigated very much yet. My guess is the prior owner left it down and moved it while hitched to a tow vehicle. When the jack is in the down position the weight of the trailer wants to sort of push it causing it to not sit vertical. At a quick glance it looks like it held in with a c-clip into something else that's welded to the frame. Is it common for these to have play and is there a fix to try before I look at replacement options?
