BCB, just to clarify, are you suggesting that the idler arm bolts may be loose? Or, that they should be adjusted? (Torsion axles are new to me).Is there anything else I should check?I did check with my local dealer, Lybacks, and Eddy said that he cannot do trailer repair. He did suggest a RV/Trailer alignment shop here in the Twin Cities that based on my research, has very favorable reviews. They quoted me $432 to align both axles.
