Hey guys, I am new to this forum. Today me and my son took out my 2011 Ranger 400 H.O., on a steep climb we lost traction and couldn't climb any further. We did spin somewhat while trying to make the climb. I backed down the hill and there was a loud clunking noise coming from the rear in reverse and drive. Does anyone have a suggestion or solution? I live 120 miles from the nearest dealer... I can most likely do some part replacement if it is minor. Thanks for your help, I am glad there are knowledgeable riders here willing to help.??????
