we got a 22' kaufman tilt bed trailer at my work... that damn thing goes though bearing like no 2morrow..... cant tell ya how many times they lost complete wheel/drum right off the damn thing. the one time the tire rolled right past them going down the road and the one guy said to the other "hey ... look at that... some dumbass lost their wheel".... 20 mins later when they get where they were going... they realized just who the "dumbass's" really were..... lmao. now we only use timkin bearings
