whlie you have her in the air release the torque on the axles and the two front pinch bolts and see if she is any better. Then torque axle bolts to proper specifications. check again if its free then the torque was to much. If its still Tight you could have a bad wheel bearing. At least this way you can isolate whethter its front or back along with torque bearing checks. I would also look closely at the brake you can pry the cylinder back with a screw driver once loose make sure they float and are not stuck. If you have never lifted the beast up before have a buddy there until you get the knack of it. picking the beast up after its flopps is heavy and embarasing!!!
Hope this helps.
