ARM - LOWER CONTROL - AWDREMOVAL
1. Raise and support vehicle.
2. Remove wheel mounting nuts (3), then tire and wheel assembly (1).
3. While a helper applies brakes to keep hub from rotating, remove hub nut (1) from the axle half shaft (2).
4. Remove belly pan.
5. Loosen nut (4) attaching lower control arm ball joint stud to knuckle (3). 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.
6. Using Puller (2), Special Tool 9360, separate ball joint stud from knuckle.
7. Remove tool.
8. Remove nut (1) from end of ball joint stud.
9. Back off nut (3) from bolt (1) attaching shock clevis bracket (2) to lower control arm (7) until it is flush with end of bolt.
10. Using a brass drift punch, tap the bolt out of the clevis bracket until bolt serrations clear bracket.
11. Remove nut (3) and bolt (1) for clevis bracket and control arm.
12. Remove mounting screws, then heat shields (3) above both inner tie rod bellows (2).
CAUTION: While steering gear bolts are removed, it important to avoid putting downward force on steering gear.
13. Remove steering gear mounting bolts as listed:
a. Left side arm - Remove bolts (3) and (4). Loosen, but do not remove, bolt (2). It is important leave bolt (2) installed to avoid dropping gear too far, putting excessive force on steering coupling.
b. Right side arm - Remove bolts (2) and (3). Loosen, but do not remove, bolt (4). It is important to leave bolt (4) installed to avoid dropping gear too far, putting excessive force on steering coupling.
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.
14. Remove bolt (3) and nut securing forward end of lower control arm (1) to engine cradle (2). If bolt has a lengthwise grooved shaft (see above note), remove bolt and nut by holding bolt stationary with a wrench, removing nut, then sliding bolt out of bushing and cradle while taking note of bolt positioning in engine cradle for reassembly purposes.
15. Remove bolt and nut (4) securing rearward end of lower control arm (1) to engine cradle (2). If bolt has a lengthwise grooved shaft (see above note), remove bolt and nut by holding bolt stationary with a wrench, removing nut, then sliding bolt out of bushing and cradle while taking note of bolt positioning in engine cradle for reassembly purposes.
16. Slide lower control arm (1) from engine cradle (2) and knuckle, and remove from vehicle.
INSTALLATION
NOTE: If installing a lower control arm engine cradle bolt that is a wheel alignment adjustment bolt (1) (identifying 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, (Refer to - SUSPENSION/ WHEEL ALIGNMENT - STANDARD PROCEDURE).
1. Slide lower control arm (1) into position in engine cradle (2) and place ball joint stem into mounting hole in knuckle.
NOTE: When installing lower control arm engine cradle bolts, it important to note that the forward bolt is installed front-to-rear and the rearward bolt is installed rear-to-front.
2. Install lower control arm mounting bolts and nuts (3 and 4). Do not tighten bolts at this time.
3. Raise steering gear to mounted position and install lower mounting bolts (2 and 3). Install upper mounting bolt (4) and nut. Tighten all mounting bolts to 122 Nm (90 ft. lbs.) torque.
4. Install heat shields (3) above both inner tie rod bellows (2). Tighten mounting screws to 7 Nm (62 inch lbs.) torque.
5. Pull downward on control arm and guide ball joint stud into knuckle (3). Install NEW nut (4) on ball joint stud. 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 122 Nm (90 ft. lbs.) torque.
6. Align shock clevis bracket (2) with lower control arm (7) bushing and install mounting bolt (1) and nut (3). Do not tighten nut at this time.
7. Install hub nut (1) on end of axle half shaft (2). While a helper applies brakes to keep hub from turning, tighten hub nut to 213 Nm (157 ft. lbs.) torque.
8. Install tire and wheel assembly (1). Tighten wheel mounting nuts (3) to 150 Nm (110 ft. lbs.) torque.
9. Lower vehicle.
10. Position vehicle on an alignment rack/drive-on lift.
NOTE: When tightening lower shock clevis mounting bolt, do not attempt rotating bolt. Bolt shaft is serrated. Turn nut only.
11. Tighten lower shock clevis bracket bolt nut (3) to 174 Nm (128 ft. lbs.) torque.
12. Perform wheel alignment.
CAUTION: If lower control arm engine cradle bolt is a wheel alignment adjustment bolt (lengthwise grooved shaft (2)), be sure to only tighten nut. Do not rotate bolt or damage to cradle will occur.
13. Once camber is found to be within specifications, tighten lower control arm cradle bolt nuts to 176 Nm (130 ft. lbs.) torque while holding the bolts stationary.
14. install belly pan.
