I'm running the same size tires on my '05 XT and lifted 2"... I'm lucky to not have had the issue you're having with axles. We have pulled many from local places and paid between $10-$25 each for them. About an hour of time and the "new" ones are in... You can pull them fast at junk yards since you don't have to be careful of the body parts or components on the donor cars.
