Spindle bearing?

[nspctr1]

I found the timken bearing numbers for the spindle but it shows 3 bearings. I need the inner and outer one. The numbers I g
Found are below.
Which ones do I need?


LM104949. Or

3780. Or

3490. Should I replace the races too?

Thx

When replacing a tapered roller bearing ALWAYS replace the race also. When a bearing wears there will be small pits in the race way and rollers. IF you only change the bearing the pits in the old raceway will accelerate the wear on the new rollers.
