If it's a Dexter Torflex you can also replace the axle with a different start angle on the spindle. My trailer sits very low which makes easier loading with my ramps but I have been considering replacing with a different start angle to raise the trailer. Would be good to time it when it needs new brakes and hubs. After over 200,000 miles I think my axle is not straight anymore as it's wearing tires on the inside with no overloading so I might have to replace it anyway. Local place that works on axles told me that the Torflex axles tend to do that when loaded close to maximum over many miles.
