First off, a real big :thanku: to Ken (AKA Akghound) because one of his suggestions got right to where I needed to be.
As noted in my previous steps in diagnoses, when I was checking the front end, I was just raising it with the bucket. As a result, not much pressure was needed to pivot the axle up and down and back and forth. Therefore, the problem was not easily noticed. But Ken offered the suggestion to just raise one side at a time and, WaaLaa, now when checking the right side first I find that the Axle Case and Bevel Gear Case are all but just hanging off the Axle Housing. Because the top end of the Bevel Gear Case was all but destroyed, the whole works were hanging with all the weight outward making it unnoticeable with both sides in the air. As per Ken's illustration of the case, Top bearing was disintegrated, one of the center bearings had nothing left but the outer ring, oil seal, collar, and large snap ring destroyed. Ordered parts Monday (just under $100.00), got them Friday, put together today and am now back in business with the 4WD.
Again, Thank you Ken.
