Installation

REAR SUSPENSION

UPPER CONTROL ARM

INSTALLATION
(1) Align the pivot bar on the upper control arm with the mounting holes in the rear suspension crossmember. Install the pivot bar attaching bolts (Fig. 36). Tighten the two pivot bar attaching bolts to 122 Nm (90 ft. lbs.).
(2) Using transmission jack, raise rear suspension crossmember up to the rear frame rails and loosely install the four attaching bolts (Fig. 35).

Fig.39 Locating Rear Suspension Crossmember In Vehicle:

(3) Position an appropriate size drift into the positioning hole in each side of rear suspension crossmember and crossmember locating holes in frame rails of the vehicle (Fig. 39). This is required to properly position rear suspension crossmember to the body of the vehicle. Tighten the four crossmember mounting bolts to 108 Nm (80 ft. lbs.). Remove drifts from rear suspension crossmember.
(4) Remove transmission jack supporting rear suspension crossmember.
(5) Install upper ball joint stud in knuckle. Install and tighten the ball joint stud nut to 88 Nm (65 ft. lbs.).
(6) Install the brake tubing above the rear suspension crossmember into the routing clips on top of the crossmember.
Install rear brake calipers onto rear knuckles.
(7) If vehicle is equipped with antilock brakes, attach wheel speed sensor heads to both rear knuckles. Tighten sensor mounting bolts to 8 Nm (75 inch lbs.).
(8) If vehicle is equipped with antilock brakes, install routing clips for wheel speed sensor cables onto brackets on both upper control arms (Fig. 32). Securely tighten routing clip attaching bolts.
(9) Install muffler support bracket on rear frame rail (Fig. 30).
(10) Install rear exhaust pipe hanger on rear suspension crossmember (Fig. 31).
(11) Install the shock absorber clevis brackets on the rear knuckles (Fig. 29). Tighten the shock absorber mounting bolts to 95 Nm (70 ft. lbs.).
(12) Install wheel and tire assembly on vehicle. Progressively tighten the wheel mounting nuts in crisscross sequence until all nuts are torqued to half specification. Then repeat the tightening sequence to the full specified torque of 135 Nm (100 ft. lbs.).
(13) Lower the vehicle.
(14) Check and reset rear wheel alignment to specifications as necessary.
