Hi, My first post having recently purchased a snapper.

I have a Series 13 Rear Engine Snapper (model E281013BE) that, to me, has excessive side-to-side movement in the rear axle. The total movement is 1/4in, is this considered excessive and if so what is causing this? I note from a parts diagram that there are several thrust washers located along the bearing, will replacing these reduce the movement?

Thanks Mike.
