Not to appear ignorant, but what "spacer" is giving you the problem? I have been all over the exploded view if the BW4470 T-case and can't find one that is accessible from the outside. Please advise.

The spacer is in the pumpkin on the end of the right axle there is some lip on the axle but not enough to hold the washer in place I don't know if the lip is wore a little or if the piece broke off

I think you you're talking about the thrust washer just inside the case. Do you have, or have access to, a fax #? If so, I will fax a copy of the exploded view and you can point out the part that is giving you the problem. Please advise.
