I would suggest contacting Dexter with the identification number of your axles; they can give you bearing information. From Dexter, here is how to get your axle ID: Dexter PDF Axle ID (clicky)
Looks like you already have the number (except it should be 9 digits); just call or e-mail Dexter and they'll help you.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
