I contacted Dexter today and if I can discover the model of the axle, they will see if they make a lift kit for it. You have to deal with a distributor and the local one does not do repairs, only sells parts. I think it is a #11 but not sure. If the rain ever stops I will go get under it and see what it is. If its a model #11 it still has 2 years left on the warranty. If that doesn't produce info I will call Rockwood. They can at least tell me the model axle.
I am sure Rockwood will suggest new axles with greater start angle, which are not in the budget at this time.
