f301359 Report post Posted October 14, 2019 Hi everyone, I thought I might service my 2011 Southwind 32VS Diff and I found this particular differential looks different. The rear cover does not come off and there’s no filler port. Is this a non service unit or is it only serviced at ford. Share this post Link to post Share on other sites
