If the vehicle is equipped with air suspension, you should turn off the air suspension system, and the switch for this is located in the area of the right kick panel.

If the vehicle is equipped with air suspension, turn off the air suspension system. Loosen the wheel lug nuts, then raise and support the rear of the vehicle. Remove the rear wheels. To remove the brake drum, spray penetration oil around the flange and studs if it's stuck due to corrosion, or remove the plug in the access hole and back off the adjuster wheel if it's locked onto the shoes due to excessive wear. Clean the brake assembly before disassembling it, then remove various components such as the secondary brake shoe retracting spring, primary shoe retracing spring, brake shoe adjusting lever, cable, guide plate, and parking brake link and spring. For shock/spring assembly replacement, position a jack under the steering knuckle, remove the nuts securing the top of the assembly, and lower the jack. Remove the lower control arm-to-spring bolt and nut, then remove the assembly. If replacing only the shock, compress the spring and remove the shock rod nut. For lower control arm replacement, disconnect the lower link nut from the Sway Bar Kit, remove the nut and bolt securing the shock/spring assembly, and remove the front and rear bushing nuts and bolts. For upper control arm replacement, remove the parking brake cable bracket bolt, upper arm-to-wheel knuckle bolt, and upper arm bushing nuts and bolts. For toe link rod removal, remove the inner end nut and knuckle nut, and remove the rod. For trailing arms removal on later models, remove the nuts and bolts securing the arms to the knuckle and frame, then install new bolts and nuts loosely. To remove the Sway Bar Kit, disconnect the end links, remove the rear suspension stone shields, and remove the Sway Bar Kit bracket-to-frame bolts. Install new nuts on the links and bracket bolts.

While both 2WD and 4WD models have similar steering knuckles, their wheel bearing setups differ. 2WD models use inner and outer tapered roller bearings on a spindle within the steering knuckle, while 4WD models employ sealed hub and bearing assemblies bolted to the knuckle.
