As for ball bearings vs rollers vs tapered rollers is that the balls have a smaller contact point with the race. Therefore lower rolling resistance
Rollers have a larger contact point and has a higher load rating vs a ball, but in regards to dia, the roller is rated to carry more
Yeah that small single contact point on our older light duty pickups is a big reason they moved away from using them on our LDT size axles and went with a roller on full and semi floating axles.
Fords F150 still has a 4800 rawr as tops for the HDPP trucks so no worries about the 3/4 ton going away anytime soon.
The last I heard is that the rear axle with the Max Payload Package is limited by the 6 lug wheels. The 2014 and earlier trucks with MPP had 7 lug wheels and a higher rear axle rating. When Ford went to aluminum bodies they decided that with the weight savings on the body they could drop to 6 lugs and retain the same payload rating.
I have not heard of any axle issues with the older trucks and their higher axle ratings.
