We have a 2011 BC3250TS. Trailer has 5,000 miles on it, On our last trip we found uneven tire wear on the front door-side tire. Took it to a Heartland warranty service center in Rapid City, SD and two different technicians there said it appeared to be a bent axel. Contacted Lippert and they sent a new one to our regular warranty dealer in Idaho so that we could continue our trip. The Idaho dealer changed the axel and returned the old one to Lippert. Two different technicians at the 2nd dealer also said it appears to be a bent axel. Lippert has now denied the warranty claim, saying that the tow and camber are within specs. The service manager at the 2nd dealer has attempted to contact Lippert and discuss this further with them, but Lippert is not returning his calls. We are out a tire, cost of the axel & labor to change the axel as well as a 300 mile trip to the dealer. What would you do next?
