Rough Country 622N2 - Manual (Page 5)

PITMAN ARM INSTALLATION INSTRUCTIONS
1. With the tire on the ground and the full vehicle weight on the suspension, move the steering left to right, check the
following for looseness, slack and wear: steering sector-to-frame attaching points, steering sector main (output)
shaft, drag link and tie rod ends, track-bar mounting points and bushings.
2. With the tires off the ground, check for improper wheel bearing pre-load and ball joint wear. IT IS VERY IMPOR-
TANT that all steering related parts are in proper working condition. If any problems exist, repair before proceeding.
3. Remove the cotter pin and nut from the drag link end where it attaches to the pitman arm. Dislodge link with a tie
rod end remover tool or by tapping with a hammer as shown. See Photo 11. NOTE - replace the link if any stud
looseness is detected or if you can twist the stud in its socket with your fingers.
4. Using an impact remove the pitman arm nut from the steering sector output shaft. See Photo 12. Using a puller tool
remove the pitman arm. Inspect the shaft splines for excessive wear, repair if needed. Retain hardware for reuse.
5. The arm and shaft splines should be clean and free of grit. Install new arm, factory lock washer and nut; torque to
170-230 Ft. Lbs.
6. Attach the cleaned drag link stud to the pitman arm. Torque slotted nut to factory specifications and install supplied-
cotter pin. NOTE - If the drag link end stud is tightened in a position other than the straight ahead position or al-
lowed to twist in the adjustment collar, vehicle drift to the left or right could occur.
7. Check for over extension (stud bind) as follows: To achieve the greatest possible linkage angle, have the truck
frame resting on jack stands with the front axle hanging at full extension travel. Check drag link ends, with the steer-
ing wheel turned full lock in both directions; to be sure studs still have the some pivot capability.
8. Check for adequate linkage clearances while turning steering wheel lock to lock. Re-torque all fasteners and double
check cotter pins.
9. Have toe-in adjustment set to factory specs.
