Assemble the couplers, drivers, and spacers according to the directions supplied. Also use the original axle spacer if your axle requires one to set axle bearing end play on the axleshafts. We went to full-floating axles, so the spacer wasn't required. Notice that the old spiders were 10-spline, and the Lock-Right is 19-spline as we upgraded to better axleshafts at the same time.
