We had new Lippert 6000# axles replaced on our 2010 Sabre 5th wheel 2 years ago, whole axle assembly, brakes and all. We had those so-called Sealed Bearing System, they were shot and not replaceable, hence new axles.... a though pill to swallow then.

Fast forward to April 24 this year, coming back from Texas we had a similar experience on I-75 near Florence, KY.

One whole wheel fell off, just like you. Incredibly, we never found it, it disappeared in thin air. My guess it fell off after hitting a pothole, and there were sooooo many big ones, unavoidable ones too.

AAA tow truck accompanied us, rolling on 3 wheels - as he could not see how he could do it with his flat bed - we drove at 20 mph to the nearest RV repair shop and believe it or not, the next day, they had installed a new Dexter 6000# axle and we were on the road back home, having pput my spare wheel/tire on.

My insurance (I'm from Canada by the way) paid it all, including hotel and meals..

I complained to Lippert by email, sent pics of the broken axle. They offered a free axle assembly to keep me happy - I no longer needed it, but had it sent to my dealer. We traded it in for a new Cougar... happy as clams. Not worried about 2nd axle shearing off.

Everyone told me it was bad weld on the axle... makes sense.
