Update and a strange situation..

You mean just take both axles out and switch sides?
I would try what JYH suggested first. If that doesn't work, this is an option. In effect, when you adjust axle bearing preload, you tighten the adjuster on the passenger side pushing both axles to the D/S seating the bearings, then back the the adjuster off to gain the desired end play.

When the adjuster is on the D/S, you are pushing both axles towards the pass side as you tighten it to seat the bearings thus increasing the pass wheel/spring clearance and decreasing the D/S clearance. If you do this don't forget to back it off to gain the desired end play.

One more tool in the bag. Good luck.
