REMOVAL & INSTALLATION
See Figure 1
The lateral links and trailing arms have rubber isolator bushings at each end. The lateral links are attached to the rear crossmember and spindle using a common bolt and nut assembly at each end. Lateral links, trailing arms and spindles are normally replaced only when the part has been damaged or when the vehicle has been involved in an accident. If a rear suspension component becomes bent, damaged or fails, no attempt should be made to straighten or repair it. Always replace with a new component. Lateral links are serviced only as complete assemblies. The bushings are not serviced separately. Service procedures for left and right sides are different. Use the following procedures.
Only frame contact or wheel lift hoisting equipment can be used on vehicles having a fully independent rear suspension. Vehicles with independent rear suspension can not be hoisted using equipment designed to lift a vehicle by the rear axle. If this type of hoisting equipment is used, damage to the rear suspension components will occur.
See Figures 2 and 3
- Raise and safely support the vehicle. Remove the left rear wheel.
- Remove the nut and bolt attaching the left lateral links to the spindle.
- Remove the nut and bolt attaching the left lateral link to the crossmember and remove the link from the vehicle.
- Install the solid lateral link on the front of the crossmember.
- Install the adjustable lateral link on the rear of the crossmember with its adjusting link closer to the spindle.
- Install the link attaching bolts at the spindle and crossmember. The bolt heads must face the front of the vehicle. Tighten the link attaching bolts to 105 ft. lbs. (140 Nm).
- Install the left rear wheel and lug nuts. Tighten the lug nuts, in sequence, to 95 ft. lbs. (129 Nm).
- Lower the vehicle to the ground.
- Have the rear wheel toe set to specifications.
See Figures 4 and 5
- Raise and safely support the vehicle. Remove the right rear wheel.
- Remove the nut and bolt attaching the right lateral links to the spindle.
- Position a transmission jack under the fuel tank just forward of the crossmember to help support the fuel tank when crossmember is lowered.
- Remove the four crossmember to frame rail attaching bolts and lower the crossmember far enough so right lateral link to crossmember attaching bolt will clear the fuel tank.
- Remove the nut and bolt attaching the right lateral links to the rear crossmember. Remove the lateral links.
Install replacement lateral links to crossmember as follows:
- Solid lateral link is installed on crossmember toward the front of the vehicle.
- The adjustable lateral link is installed on crossmember toward rear of vehicle, with the adjustable link positioned toward the spindle.
- Install the right lateral links attaching bolts at the crossmember with the heads of the bolts facing toward the front of the vehicle.
- Position the crossmember on the frame rail and install the four attaching bolts. Tighten attaching bolts to 70 ft. lbs. (95 Nm). Remove the transmission jack from under fuel tank.
- Tighten the lateral link to crossmember attaching bolt to 105 ft. lbs. (140 Nm).
- Align the lateral link with the spindle and install the lateral link to spindle attaching bolts. Tighten the bolts to 105 ft. lbs. (140 Nm).
- Install the right rear wheel and lug nuts. Tighten the lug nuts, in sequence, to 95 ft. lbs. (129 Nm).
- Lower the vehicle and check the toe setting of the rear wheels. Adjust the toe to specifications as required.
