    Default Re: Lost the camber on a trailer axle.......What does that mean?

    Trailer axles, that is the steel pipe itself, are bent at the factory, to produce camber on the wheels. i.e. the top of the wheels will tilt out. The idea is that as the axle is loaded the wheel will move to a more vertical position. It is possible for someone to install the axles upside down and then when the axles are loaded the wheels tilt in at the top which will quickly wear the tires. I would be suspecting worn spring bushings or alignment based upon the symptoms you have provided.

    I would contact the axle manufacturer, most likely Dexter or one of the other major brands. I know Dexter had a few mis-manufactured axles and will replace upon request.

    Worth the cost of a phone call.

Although that would depend on quality of tires. There are a couple of types of axles and weight capacities. The axles need to be rated for more that the gross weight of the trailer or they will fatigue and bend as you describe. I would say you need either heavier axles or a better engineered trailer. Although the flip side of that is are you overloading the trailer? If you are traveling much you should be able to come across a truck stop with a weigh scale that you can weigh the trailer when you have it "fully" loaded. If you are unhappy with your dealer try a different dealer or type of trailer dealer. Also you can try to contact an trailer axle dealer online and they should be able to give you answers you need with a call or email. The axles should have a data plate on them giving you make, model and weight capacity.

    Good Luck

    I agree the trailer needs better engineering. Keep in mind this is $50k trailer. The dealer said you can twist an axle be running over train tracks at 70 mph with the brakes applied.

    What is the repair for the camber?
    Bent axle and axle replacement?

    What do the axles look like? It sounds like the tires should appear visibly bent outward. But, that should only happen with an overloaded trailer. Twisted backwards?

    I would tend to agree with others that it sounds like the axle is undersized. Your trailer axles should take a lot more abuse than hitting a small animal on the road, or running through a pothole.

    I certainly wouldn't let the dealer put in an identical replacement axle.
    No buffalo. I agree to much damage. I can understand the belly covering and plumbing, thats not very sturdy stuff, but the running gear?

    The axle still have their upwards crown and the tires don't seem bent out anything obvious.

    I mentioned about upgrading from 5200# axles to 7000# but the guy looked at me like I was from mars. He said it would be way to stiff, it would bounce the trailer apart.

    I think your correct. I think there is something wrong with the trailer, frame not welded square from factory, axles not aligned properly or undersized.

    The crown is up. I doubt the spring bushing were worn last year at 250 miles. Alignment is the problem, I'm pretty certain.

    I believe they are Lieberts. That would be three bad axles. One "faulty" one last year and now two more. I think its a forest river issue not liebert issue.

    They are torsion axles. So today the dealer came up with the idea to upgrade from 5200# axles to 6000# axles all by himself.

    Looks like they may run this through warranty. The trailer is 2 years old now so the warranty is expired. The may cover two of the four tires.
