Thanks for the quick response. We are looking to acquire our first 5r. Looking at SOB, I've found a long trail of years of unresolved leaking seals on Lippert axles. We are looking at a 3791RD as well as similar from other manufacturers.
Pretty sure Lippert has always used dexter axles, as do a majority of other manufacturers. At least for us over the years, axles are one thing we have never had a problem with. I have heard of folks damaging their seals by either reusing during a bearing repack, or using an electric or compressor grease gun with the EZ hubs. Neither of those can be blamed on dexter.
