Atlas axle, is my crush washer knackered??!

[tombstone]

Well, I have a pinto powered locost, pretty much built as per the original book.. my axle has developed a rattle. The pinon oil seal 'dust shield' is loose and rattling. Is this the curse of an atlas axle when the pinon bearings need doing?? Its done a few runs at santa pod, and a track day at Goodwood, but it was on the way home from MOT I noticed the rattle!!! I'm assuming its a new crush washer and some bearings required, but anyone can shed some light be appreciated!!!

Seek a specialist repair,the pinion crush tube needs to be torqued to set preload and pinion mesh to avoid wear and noise if not set properly.
