Green Wheel bearing help

In 40+ years of servicing vehicles,, I have replaced about 2 dozen worn out front tapered wheel brgs... apprx $20 a set..

In the last 10 yrs I have replaced at least that many front (ball bearing) hubs, plus a coupla rear hubs.. avg $120 each..

I've come to the conclusion that the ball brgs don't last as long as tapered roller bearings,, perhaps cuz the "hubs" can't be serviced (repacked), but not sure I believe that... jmo
