Snapper Auger Gearbox~model 8261

Greetings, This Snapper gearbox works well so the gears should be OK. The auger shaft seals are shot, also there is lateral movement of the housing, that is I can move it, the housing, back and forth in line with the auger shaft.

Is this normal, I see there are Thrust Washers, should there be this movement?

What's your thought?

Thanks Richard
