Hi: Peter Crowl... One thing Bolers aren't is "Rocket Science". Usually the appliance side, fridge
, stove, sink and furnace(if equip'd), is a little lower than the closet side. That said I'd put my $$$'s on the axle being shot.
You can check Dexters web site and look up a #9 2200lb. Torsion axle spec's. That's the one that most people use now. They will make them to the exact tube length that you require. Once replaced the trailer will sit higher and ride better. One fly in the oinkment could be changing from a leading arm to a trailing arm axle and making sure it's centered in the wheel opening!!!
The Scout model used a 1250lb. and the Voyageur and Deluxe models used a 1650lb axle as std equip...at least the Earlton Ontario factory did in '77.
