37\" tires or bigger with crossover, Do you have Pitman shaft bearing wear? I am finishing up a PM on the K5, ( I started out just to replace the ORD spring bushings) and found the Pit shaft wobbling slightly. The top cover was loose, but tightening didn't fix it. The 2WD box has only seen maybe 6-8 hard wheelin trips, since I rebuilt it. Anybody else have issues in that area?
