Timken rear wheel bearing installation
While I will agree the tapered is a better design over all there isn't anything wrong with the ball bearing. If you were building an auto cross car or a car for drifting then yeah the tapered would be better......but honestly if you were building a car for those types of racing you'd probably be going to an independant type rear not a solid axle. My 3/4 Cummins Truck and my Wife's Durango both use the ball type rear axle bearings and have not had a failure.....and like Chuck said they are worse than the Green Style......now that I have said that I will have to fix one of them....you will be fine with the green bearings.
