For those naysayers. Since you know so much, you call Lippert and see what they tell you. I did and they denied that I had Lippert axles. When I stated the they had the Lippert name and LCI on the labels the stated they did not sell parts. The OP statement is very true of how they operate. We all know their frames are a POS. I spent over a week trying to get a bearing from them and some of the best bearing houses around. NONE was to be found. They also told the manufacture of my fifth wheel that they did not have parts and would not be get anymore and that I would have to buy a new axle.
That is when I decided to buy axles from Dexter because "Why would I buy an axle from them if I could not get parts for it after a short time." In my case less then five years.
If you have a DRV product crawl under it and see what you have and good luck with it. Other manufactures also use their axles.
