rayaustin0081 Report post Posted November 18, 2015 I have a 2003 Southwind on a W22 chassis, Recently I was backing slowly up a slight grade and turning at the same time to get onto a site. The surface was sand and gravel. I started hearing and feeling a "metal to metal" sound and felt a jerking that seemed to come from the rear under-carridge. My mechanic suggested it may have something to do with a limited slip differential. It happened again while backing straight into a building with a 2" rise to get up on the floor. It sounds like a gear slipping. Anyone have any experience with this sort of thing?? Share this post Link to post Share on other sites
dickandlois Report post Posted November 19, 2015 rayaustin0081, Welcome to the FMCA Forum. Has the differential oil been changed? Has your mechanic taken a look at your rear axle? Strange sounds coming from the rear axle or differential should be checked by a qualified mechanic.. Not sure the RV chassis come with limited slip differentials. The rear axle on your coach came with a synthetic oil and should last for 200,000 plus miles, but under dirty conditions that number is reduced. Weight axle can handle 16,500lbs.
