16. We won’t go into details on spindle installation as we’ve covered it on builds in the past. However, it’s worth pointing out that the thrust bearing should be packed with grease, and installed with the dust shield up toward the bottom of the axle boss. Shims are provided if required, and should be placed above the thrust bearing if used. Also, be sure to orient the notch in the kingpin with the lock pin hole in the axle during installation, unlike we’re doing here!
