12. Using a 19/32” drill bit, drill the two (2)
holes closest to the ball thru the bed. Do
this on both sides of the center section.
13. Insert the 1/2”-13 u-bolts thru the holes
from the topside. Install a 1/2” flat washer,
a spring, another 1/2” flat washer and
1/2”-13 lock nut onto each u-bolt stud.
Tighten until the washers are touching the
spring without compressing it.
14. Reinstall the exhaust to the factory
hangers. Reinstall the spare tire per the
vehicles owners manual.
11. Check the rotation of the top collar at
this time to insure the bed is not rubbing
against it and it can rotate freely. If
necessary drop the center section and
remove any obstructions.
Once rotation is checked, fully tighten
all hardware to the appropriate torque
specifications.
