(12) Assemble and install socket and 0-50 foot-pound
(0-68 N«m) capacity torque wrench on bolt previously
installed in steering knuckle.
(13) Rotate steering knuckle slowly and steadily
through complete arc and measure torque required to
turn knuckle.
(14) Install bolt, flat washer, nut, torque wrench and
socket on opposite steering knuckle and measure torque
required to rotate knuckle.
(a) If reading is less than 10 foot-pounds (14
N®m) steering effort is within specifications and fault is
not in knuckle ball studs. Check for tight or damaged tie
rod ends, lubricate or replace as necessary, and proceed
to next step.
(b) If torque reading is more than 10 foot-
pounds (14 N*m), turning effort is excessive. Proceed to
Ball Stud Preload Correction procedure.

foot-pounds (47 N®m) torque and install replacement
cotter pins.
(16) Install connecting rod. Tighten connecting rod
retaining nuts to 60 foot-pounds (81 N*m) torque on CJ
models and 75 foot-pounds (102 N»m) torque on all other
models. Install replacement cotter pins.

N O T E : If the cotter pin holes in the nut and stud are
not aligned, tighten the nut (only) to align the holes:
Never loosen the nut to align the holes.
(13) Install front axle shafts and steering spindles
* loosely and measure turning effort of each steering
knuckle as described in Ball Stud Preload Measurement.
(a) If turning effort is less than 10 foot-pounds
(14 N*m) torque, proceed to next step.
(b) If turning effort is more than 10 foot-pounds
(14 N*m) torque, replace upper and lower ball studs and
repeat Ball Stud Preload Correction procedure.
(14) Install front axle shafts.
(15) Connect tie rod to steering knuckle arms.
Tighten tie rod end retaining nuts to 45 foot-pounds (61
N®m) torque and install replacement cotter pins.

necting rod end retaining nut to 60 foot-pounds (81 N*m)
torque on CJ models and 75 foot-pounds (102 N*m)
torque on all other models.
(17) Connect steering damper to tie rod, if equipped.
(18) Install front wheels. Tighten wheel retaining
nuts to 80 foot-pounds (108 N®m) torque.
