I have had to replace both rear axle tires before the fronts already. I mentioned this to the dealer but they didn't seem too concerned. The axles are positioned under the springs from the factory so that isn't an option. If I could find an equalizer with a longer arm would it be unsafe? Assuming the distance between spring "eyes" is the same. Yes, I know what happens when you assume!!! MY loving bride is making noises about a new trailer within the next year so this may be a mute point but, something I need to watch for with a new(er) one.
