ARM - LOWER CONTROL - RWDREMOVAL
1. Raise and support vehicle.
2. Remove wheel mounting nuts (3), then tire and wheel assembly (1).
3. Remove belly pan.
4. Remove screws (1) fastening stabilizer bar heat shield (3) on side of control arm repair.
5. Remove bolts (2) fastening stabilizer bar bushing retainer (1) in place on side of control arm repair.
6. Remove retainer halves (1)(2) from around stabilizer bar bushing (3).
7. Utilizing slit, remove bushing (1) from stabilizer bar (2).
NOTE: In the following step, the lower control arm cradle bolt (3) is accessed through the opening (2) created by removal of the bushing from the stabilizer bar (4).
CAUTION: If the lower control arm bolt at the engine cradle has a lengthwise grooved shaft (2), it is a special wheel alignment adjustment bolt and the bolt head (1) must not be rotated in the vehicle or damage to the bolt and engine cradle will result. While holding the bolt in place with a wrench, remove the nut, then slide the bolt out of the bushing and cradle taking note of bolt positioning in engine cradle for reassembly purposes. The bolt needs to be installed in the same position as removed to make sure wheel camber and caster return to adjusted position.
8. Remove bolt and nut (1) securing lower control arm (2) to engine cradle. If bolt has a lengthwise grooved shaft (see above note), remove bolt and nut by holding the bolt in place with a wrench, removing nut, then sliding bolt out of bushing and cradle while taking note of bolt positioning in lower control arm bushing for reassembly purposes.
9. Remove bolt (3) securing shock assembly (1) to lower control arm (4).
10. Remove screw (3) fastening wheel speed sensor to knuckle (1). Pull sensor head (4) out of knuckle.
11. Remove wheel speed sensor cable routing clip (2) from brake flex hose routing bracket (5).
12. Loosen nut (5) attaching ball joint stud to lower control arm (4). Back nut off until nut is even with end of stud. Keeping nut on at this location will help keep end of stud from distorting while using Puller in next step.
CAUTION: In following step, use care not to damage ball joint seal boot while sliding Puller, Special Tool 9360, into place past seal boot.
13. Using Puller (1), Special Tool 9360, separate ball joint stud (2) from lower control arm.
14. Remove nut (5) from end of ball joint stud attaching lower control arm to knuckle.
15. Pry knuckle downward and slide ball joint stud out of lower control arm. Position knuckle outward, away from lower control arm.
16. Slide lower control arm out of engine cradle and remove from vehicle.
INSTALLATION
NOTE: If installing a lower control arm engine cradle bolt that is a wheel alignment adjustment bolt (1) (lengthwise grooved shaft (2)), make sure to install it in the same position which it was in upon removal. For more details on installation of this special bolt.
1. Slide lower control arm (4) into position in engine cradle and install mounting bolt from rear.
2. Install nut (1) on lower control arm cradle bolt, but do not tighten at this time.
CAUTION: Before installing knuckle to lower control arm, measure height of ball joint seal boot (1) mounted on knuckle. If seal boot height is above 25.5 mm, any air inside seal boot must be expelled. To do so, follow these steps.
^ Tip ball joint stud completely to one side.
^ Using thumb and index finger, gently squeeze seal boot together at center expelling any air. Do not allow grease to be release.
^ Push down very top of seal boot.
^ Return ball joint stud to original "centered" position.
^ Measure ball joint seal boot height (1) making sure it is within specification.
^ Wipe any grease from ball joint stud.
3. Pull knuckle (1) downward and position lower control arm (4) over ball joint stud. Release knuckle, guiding stud into lower control arm. Install NEW nut (5) on ball joint stud attaching lower control arm (4) to knuckle (1). Tighten nut by holding ball joint stud with a hex wrench while turning nut with a wrench. Tighten nut using crow foot wrench on torque wrench to 68 Nm + 90° turn (50 ft. lbs. + 90° turn) torque.
4. Install wheel speed sensor head (4) into knuckle and install mounting screw (3). Tighten screw to 11 Nm (95 inch lbs.) torque.
5. Attach wheel speed sensor cable and routing clip (2) to brake flex hose routing bracket (5).
6. Install lower shock mounting bolt (3) attaching shock assembly (1) to lower control arm (4). Do not tighten bolt at this time.
7. Install tire and wheel assembly (1). Tighten wheel mounting nuts (3) to 150 Nm (110 ft. lbs.) torque.
8. Lower vehicle.
CAUTION: Because stabilizer bar is disconnected at cradle it is important to use extra care while moving vehicle to alignment rack/drive-on lift.
9. Position vehicle on an alignment rack/drive-on lift.
10. Tighten lower shock mounting bolt (3) to 174 Nm (128 ft. lbs.) torque.
11. Perform wheel alignment.
CAUTION: If the control arm engine cradle bolt is a wheel alignment adjustment bolt (lengthwise grooved shaft (2)), be sure to only tighten the nut. Do not rotate the bolt head (1) or damage to the bushing will occur.
12. Once camber is found to be within specifications, using a crowfoot wrench, tighten lower control arm cradle bolt nut (1) to 176 Nm (130 ft. lbs.) torque while holding the bolt stationary.
CAUTION: Because of stabilizer bushing outer shape, it is very important to install bushings in position discussed in following step.
13. Utilizing slit in bushing, install stabilizer bar bushing (1) against locating collar on stabilizer bar (2) as shown. Make sure slit in bushing is positioned toward rear of vehicle.
14. Install stabilizer bar bushing retainer halves (1)(2) around bushing (3).
15. Install bolts (2) securing stabilizer bar bushing retainer halves (2) to cradle. Tighten bolts (2) to 60 Nm (44 ft. lbs.) torque.
16. Install stabilizer bar heat shield (3) over stabilizer bar bushing retainer. Install mounting screws (1).
17. Install belly pan.
