Axle issue... The spring shackle on one side broke, causing axle torque on opposite side, resulting in brake on that side to lock, overheat, burn up everything....thus all the smoke we spotted while driving down the NJ Turnpike. The spindle threads are stripped, cotter pin held the hub nut on so thankfully wheel didn't fly down road. And we were able to get off to the side of another freeway sort of safely but a cop waved us on. Ended up at next available place, Wendy's parking lot. So needs new brakes, bearings, and spindle repair.
Due to problems under warranty with the original axles, Forest River replaced the 3500# with 5200# Lippert axles and new tires, etc... Which compounds the repair issue, we learned, when our mechanic had no idea how to find a new axle that size and suggested we start calling for one ourselves. Which we did. Lippert said they would need to manufacture a replacement, and God only knows when it will arrive. When we asked about paying to expedite, got nowhere. Have not found anyone with a 5200# nearby, otherwise that would be faster and more sensible I think.
