My 2017 Jayco 28 BHBE (slightly longer and slightly heavier) has 4400 pound Lippert axles on it. I know this because I just had to deal with Lippert on an issue with the brakes. Other than that the axles have been fine with no problems at all. After reading what Lynnmor wrote maybe the 4400 pound axles would be something to suggest to Jayco or your dealer. I agree with Old-Biscuit, go straight through Jayco or better yet straight to Lippert like I did, cutting out all the middle men. I personally had very good dealing with Lippert on my brake issue. It is odd that you have had this happen twice now on a mostly new TT. I'm sure that your TT isn't the only one that Jayco/Lippert has installed these axles on. Therefore if it is a manufacturer problem then you shouldn't be alone. If you are indeed alone on this issue then it sounds like something on your end. Lots of good suggestions here.
