8 3/4 axle end play question ??

I had this issue once a long time ago. The adjuster on the passenger side would not screw far enough in(clockwise). It made the pass side tight with no play. I changed the bearing and adjuster and all was fine. Btw the thrust block is 1 1/2 inches wide while the pins in the clutch u it are 1 3/8 wide. Kim
