Clean up the the shaft with some emery cloth. When you replace the seal make sure you pack the lip of the seal with some petroleum jelly.

It's a fine type of sand paper for polishing metal.

Also make sure your drive line angles are correct and your output bushing is in good shape.

Plowking, Can you see/feel a groove on the yoke where the seal has been riding? How much yoke is slid into the transfer case?
