chrysler pacifica stabilizer bar bushing replacement

Inspect both lower control arm isolator bushingsfor severe deterioration, and replace as required. If abushing fails, the lower control arm must bereplaced.

Inspect and test the ball joint per the procedurelisted in Lower Ball Joint. (Refer to 2 - SUSPEN-SION/FRONT/LOWER BALL JOINT - DIAGNOSISAND TESTING)

INSTALLATION(1) Position lower control arm into brackets on

engine cradle (Fig. 17).

NOTE: If equipped with flag nuts, when installinglower control arm-to-cradle REAR mounting bolts,ensure flags on mounting nuts are positioned asfollows 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 down-ward (below LCA)Flags on front mounting nuts are self explanatory.

(2) Install NEW bolts attaching lower control armbushings to engine cradle (Fig. 17). Install bolts fromrear as shown. Thread bolts into properly positionednuts (with flags if equipped. See preceding note).Do not tighten bolts at this time.

(3) Install steering knuckle, brake rotor and cali-per. (Refer to 2 - SUSPENSION/FRONT/KNUCKLE -INSTALLATION)

(4) Install tire and wheel assembly (Refer to 22 -TIRES/WHEELS - INSTALLATION). Tighten wheelmounting 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 mountingbolts.

(7) Tighten lower control arm frame mountingbolts to 163 N·m (120 ft. lbs.) torque.

(8) Perform wheel alignment. (Refer to 2 - SUS-PENSION/WHEEL ALIGNMENT - STANDARDPROCEDURE)

STABILIZER BAR

REMOVAL(1) Raise and support vehicle. (Refer to LUBRICA-

TION & MAINTENANCE/HOISTING - STANDARDPROCEDURE)

(2) Remove both front wheel and tire assemblies.(3) Remove nut attaching outer tie rod to steering

knuckle by holding rod end stud stationary whileloosening and removing nut with a wrench.

(4) Remove tie rod end from steering knuckleusing Remover, Special Tool C-3894-A (Fig. 18).

CAUTION: When removing nut from stud of stabi-lizer bar link, do not allow stud to rotate in it’ssocket. Hold stud from rotating by placing an open-end wrench on flat machined into stud (Fig. 19).

(5) Remove stabilizer bar links from each end ofstabilizer bar (Fig. 19). To do so, place an open-endwrench on flat machined into link’s mounting stud,then remove nut while holding wrench in place. Pusheach stud out of hole in stabilizer bar.

(6) Remove stabilizer bar cushion retainers as fol-lows (Fig. 20):

(a) Loosen front bolts at each retainer (Do notremove). An open-end wrench works best, but asocket may be used if correct length extension isused.

(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, andback-and-forth as necessary.

INSPECTIONInspect for broken or distorted stabilizer bar bush-

ings (cushions), bushing retainers, and worn or dam-aged stabilizer bar links. Also inspect retainers fordamaged heat shields and missing or damaged rivets.

INSTALLATION

NOTE: When installing stabilizer bar, make sure itinstalled so that bar curves upward at ends to meetstabilizer links (Fig. 21).

(1) Insert stabilizer bar over cradle through rightfront wheel opening in reverse direction it wasremoved in. Ensure bar gets routed in front ofbrake tubes on cradle.

NOTE: When installing cushion retainers, makesure shielded retainer is installed on right side withshield pointing forward.

(2) Install cushions on stabilizer bar utilizing slitsin cushions. Install each cushion so its slit faces for-ward and flat side is positioned toward cradle onceinstalled (Fig. 21).

(3) Install retainers on cushions. Make sureretainer with shield is placed over right cushion withshield facing forward.

(4) Slide stabilizer bar forward engaging slottedholes on retainers with retainer mounting bolts incradle.

(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 sureheat shields are not bent or mis-positioned.

(7) Install each stabilizer bar link mounting studthrough hole in each end of stabilizer bar.

CAUTION: When installing nut on mounting stud ofstabilizer bar link, do not allow stud to rotate in it’ssocket. Hold stud stationary by placing an open-end wrench on flat machined into stud (Fig. 19).

(8) Hand-thread nut on end of each stabilizer barlink studs. Then hold studs from turning by placingan open-end wrench on flat machined into each link’smounting 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. Startnut onto tie rod stud. While holding stud stationaryusing a socket, tighten nut using a wrench. Using acrowfoot wrench on a torque wrench, tighten nut to47 N·m (35 ft. lbs.) torque. Then, tighten nut anadditional 1/2 (180°) turn after that torque is met.

(10) Install tire and wheel assembly (Refer to 22 -TIRES/WHEELS - INSTALLATION). Tighten wheelmounting nuts to 135 N·m (100 ft. lbs.) torque.

(11) Lower vehicle.

STRUT ASSEMBLY

DESCRIPTIONA Macpherson type strut assembly is used in place

of a conventional front suspension’s upper controlarm and upper ball joint. The bottom of the strutmounts directly to the steering knuckle using twobolts and nuts going through the strut clevis bracketand steering knuckle. The top of the strut mountsdirectly to the strut tower of the vehicle using thethreaded studs on the strut assemblies upper mount.

The strut assembly includes the components listedin the figure (Fig. 22).

Each component is serviced by removing the strutassembly from the vehicle and disassembling it.

Left and right springs must not be interchanged.Coil springs are rated separately for each corner orside of the vehicle depending on optional equipmentand type of vehicle service. If the coil springs requirereplacement, be sure that the springs are replacedwith springs meeting the correct load rating andspring rate for the vehicle and its specific options.
