Had a trailer mishap a couple of years ago and bent the tow bar or tongue bar or whatever it's called. Goes down the road OK, don't pull much. But it does wear my tires unevenly and those cheap-*** things cost a fortune and didn't last 3500 miles when it was straight. Any suggestions on how I might straighten that? Tried a sledge. Tried a pipe wrench, big cheater bar and a torch, but looked like the wrench (Chinese pot metal) was ready to bust. Could a machine shop do it and what would be a ballpark figure, ya think? Thanks.
