12. Before installing the 5/8” carriage bolts through the hitch, the U-Block shims must be placed between the hitch and
the bed and between the cross members and the bottom of the bed , (see Figure 9.). These shims are necessary to
prevent the bed corrugations from collapsing when the bolts are tightened.
13. Align the rearward cross member with the 5/8” diameter drilled holes.
14. Install the 5/8 X 2.50 GR5 carriage bolts through the hitch, shims and cross members. Secure with lock washers and
nuts. Torque nuts to 150 ft.-lb. (203 N-m).
15. Install the (2) U-bolts through the hitch. From under the vehicle install the large flat washer over the U-Bolt
followed by a spring, another large flat washer and secure with a thin 5/8” jam nut. Repeat for the other legs of the
U-Bolts. The 5/8” jam nuts are tightened until (3) threads are visible past the bottom of the jam nut.
16. Torque the 5/8-11 GR8 nuts connecting the rearward cross member to the brackets to 150 ft.-lb. (203 N-m).
17. If the wire harness was loosened to install the rear driver’s side frame bracket u-bolt and cannot be reattached using
the existing fasteners, use the cable tie to attach the wires to the u-bolt.
18. Reinstall the exhaust, and reinstall the spare tire shield if removed. Raise the spare tire back in to position. Reattach
the ground wire, through the large hole in the Driver’s side frame bracket on 2010 and newer model year vehicles.
