links until bushings bulge slightly.
8. Adjust sway bar on axle so that there is at least 3/4” clearance between the bar and the axle. Ensure adequate clearance
between the sway bar and all shock absorbers, brake lines, hoses, cables and electrical connections. When all clearances
are confirmed, tighten U-bolts to 60 ft-lb. Double nut and tighten.

plug to speed sensor.
10. Bounce vehicle and check for clearance on all undercarriage components. Recheck installation, look for clearance on gas
