Get the specs. And ensure they are installed correctly. The old cup-and-cone bearings on my '47 1.5 ton need 33 ft-lb on them, then back off to first castellatiuon on the nut. So they run with a lot of preload.
I expect that tapered rollers will run with a small amount of play (ie do up until just starting to tighten by fingers, back off to first castellation).
