If I'm remember correctly the adjuster should be on the passenger side, they say to install the driver side axle first and tighten up all five nuts so they are tight, then install the passenger side and set the end p[ay on it to be from.0005 to no more than .006. I think. I shoot for .0005 to .0030 end play max with stock axles bearings, zero with green axle ball bearings
Tapered Timken axle and wheel bearing are designed to be use with preload on them so minimum end play will work fine
