I watched the Vids late last night Grumpy.
Very Educational & Interesting.
I have not ever used Ceramic Ball Bearings.
Maybe I will have a chance to try them out in a Ford 9" inch rear diff build in 2016.
Curious also if replacement CERAMIC Timken style Tapered Roller bearings are available for the Dana 60 & Pontiac 9.3 Rear Diffs.
Low friction qualities & low material distortion of Ceramic is Intriguing.
Ceramic Ball Bearings have revolutionized the Turbo Charger world.
During WW2 the Allied Forces Bombed all the Ball Bearing plants in Nazi occupied Germany.
Screwed Adolf Hitler....
