(4) Remove tie rod end from steering knuckle using Remover, Special Tool C-3894-A (Fig. 18).
INSTALLATION (1) Position lower control arm into brackets on engine cradle (Fig. 17). NOTE: If equipped with flag nuts, when installing lower control arm-to-cradle REAR mounting bolts, ensure flags on mounting nuts are positioned as follows to avoid contact with lower control arm (LCA) once bolts are tightened: • Left LCA rear flag nut – flag positioned upward (above LCA) • Right LCA rear flag nut – flag positioned downward (below LCA) Flags on front mounting nuts are self explanatory. (2) Install NEW bolts attaching lower control arm bushings to engine cradle (Fig. 17). Install bolts from rear as shown. Thread bolts into properly positioned nuts (with flags if equipped. See preceding note). Do not tighten bolts at this time. (3) Install steering knuckle, brake rotor and caliper. (Refer to 2 - SUSPENSION/FRONT/KNUCKLE INSTALLATION) (4) Install tire and wheel assembly (Refer to 22 TIRES/WHEELS - INSTALLATION). Tighten wheel mounting nuts to 135 N·m (100 ft. lbs.) torque. (5) Lower vehicle. (6) Position vehicle on alignment rack/drive-on hoist. Raise vehicle as necessary to access mounting bolts. (7) Tighten lower control arm frame mounting bolts to 163 N·m (120 ft. lbs.) torque. (8) Perform wheel alignment. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE)
STABILIZER BAR REMOVAL (1) Raise and support vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCEDURE) (2) Remove both front wheel and tire assemblies. (3) Remove nut attaching outer tie rod to steering knuckle by holding rod end stud stationary while loosening and removing nut with a wrench.

CAUTION: When removing nut from stud of stabilizer bar link, do not allow stud to rotate in it’s socket. Hold stud from rotating by placing an openend wrench on flat machined into stud (Fig. 19). (5) Remove stabilizer bar links from each end of stabilizer bar (Fig. 19). To do so, place an open-end wrench on flat machined into link’s mounting stud, then remove nut while holding wrench in place. Push each stud out of hole in stabilizer bar. (6) Remove stabilizer bar cushion retainers as follows (Fig. 20): (a) Loosen front bolts at each retainer (Do not remove). An open-end wrench works best, but a socket may be used if correct length extension is used. (b) Remove rear bolts at each retainer. (c) Slide stabilizer toward rear of vehicle. (d) Remove both retainers and cushions from bar. (7) Remove stabilizer bar out through right wheel opening by carefully rotating bar up-and-down, and back-and-forth as necessary.
INSPECTION Inspect for broken or distorted stabilizer bar bushings (cushions), bushing retainers, and worn or damaged stabilizer bar links. Also inspect retainers for damaged heat shields and missing or damaged rivets.

Inspect both lower control arm isolator bushings for severe deterioration, and replace as required. If a bushing fails, the lower control arm must be replaced. Inspect and test the ball joint per the procedure listed in Lower Ball Joint. (Refer to 2 - SUSPENSION/FRONT/LOWER BALL JOINT - DIAGNOSIS AND TESTING)

INSTALLATION NOTE: When installing stabilizer bar, make sure it installed so that bar curves upward at ends to meet stabilizer links (Fig. 21).
(2) Install cushions on stabilizer bar utilizing slits in cushions. Install each cushion so its slit faces forward and flat side is positioned toward cradle once installed (Fig. 21). (3) Install retainers on cushions. Make sure retainer with shield is placed over right cushion with shield facing forward. (4) Slide stabilizer bar forward engaging slotted holes on retainers with retainer mounting bolts in cradle. (5) Install rear retainer mounting bolts. (6) Tighten all four retainer mounting bolts to 54 N·m (40 ft. lbs.) torque (Fig. 20). NOTE: Once retainer bolts are tightened, make sure heat shields are not bent or mis-positioned. (7) Install each stabilizer bar link mounting stud through hole in each end of stabilizer bar. CAUTION: When installing nut on mounting stud of stabilizer bar link, do not allow stud to rotate in it’s socket. Hold stud stationary by placing an openend wrench on flat machined into stud (Fig. 19).

(8) Hand-thread nut on end of each stabilizer bar link studs. Then hold studs from turning by placing an open-end wrench on flat machined into each link’s mounting stud, then tighten each nut (Fig. 19). Tighten each nut to 88 N·m (65 ft. lbs.) torque. (9) Install outer tie rods to steering knuckles. Start NEW nut onto stud of each outer tie rod. Start nut onto tie rod stud. While holding stud stationary using a socket, tighten nut using a wrench. Using a crowfoot wrench on a torque wrench, tighten nut to 47 N·m (35 ft. lbs.) torque. Then, tighten nut an additional 1/2 (180°) turn after that torque is met. (10) Install tire and wheel assembly (Refer to 22 TIRES/WHEELS - INSTALLATION). Tighten wheel mounting nuts to 135 N·m (100 ft. lbs.) torque. (11) Lower vehicle.
STRUT ASSEMBLY DESCRIPTION A Macpherson type strut assembly is used in place of a conventional front suspension’s upper control arm and upper ball joint. The bottom of the strut mounts directly to the steering knuckle using two bolts and nuts going through the strut clevis bracket and steering knuckle. The top of the strut mounts directly to the strut tower of the vehicle using the threaded studs on the strut assemblies upper mount. The strut assembly includes the components listed in the figure (Fig. 22). Each component is serviced by removing the strut assembly from the vehicle and disassembling it. Left and right springs must not be interchanged. Coil springs are rated separately for each corner or side of the vehicle depending on optional equipment and type of vehicle service. If the coil springs require replacement, be sure that the springs are replaced with springs meeting the correct load rating and spring rate for the vehicle and its specific options.
