FOOTNOTE: This is the SKF crossover bearing-cup set you can use vs the Timken part listed in the FMC manual. Set= 1-conical bearing & 1-cup.
Note: After I'd reassembled both my axles 'reusing' the (freshly greased) old bearing/cup sets I discovered the pass-side shaft had about 40-50 thou end-play in the shaft.
After you unhook the propeller-shaft from the drive-yoke on the end of the shaft, you can easily measure your end-play by popping off the grease cap on the outer drive flange (exposing the end of the drive shaft) then use a Vernier (the thin pointy depth measuring shaft) and then take measurements after pulling the shaft inwards and then pushed outwards and compare the measurement. Talked to a Timken rep and the consensus was that mine was excessive. Bought a couple of new SKF sets (above) as changing out the bearings seemed the only thing left to do to fix it. I was kind of freaking actually until I put a Vernier on the old bearings and discovered the new SKF's were roughly 20-thou wider than the old ones. So I wondered then if the 2 x 20-thou (= 40 thou) extra width of these new ones was the solution to my shaft issue? Reinstalled the new ones and WHAM-O... no end-play in the shaft! My hunch is, just a hunch, this was the first time the inner shaft bearings were done on my coach after 85,000 miles and it may have resulted in accelerated wear, as they're supposed to be done every 25,000 miles. Wheels are going back on #846 today!
