I am in need of a front transfer case cover (246) for a 1999 chevy 4x4 silverado pickup. The area where the front driveshaft bearing sits is worn and allows the bearing (which is fine) to move, thus causing a porr seat and left it clunk and vibrate as well as spraying fluid out. If any one has one they can part with, or knows where I can get one I would be appreciative for the info. My email is tpyles@gfn.org Thanks for your time. 200,000 miles and running strong!
