For any repair or servicing of an axle beam on a car with rear disc brakes, make sure you first disconnect the negative battery cable and allow the air bag system capacitor to release. Open the cover over the air cleaner to reach the battery and then put blocks under each tire so the vehicle cannot move. After taking out the center console, lift the parking brake lever output cable to secure the automatic adjustment mechanism. Pull the rear parking brake cables off the equalizer, support the car by raising it and get rid of the wheel assembly. Pull the brake flex line away from the axle trailing arm, take off the caliper and set it in place and remove the brake rotor and dust cap. Slide the hub with the bearing off the spindle, take away the parking brake shoes and separate the parking brake actuator lever. Take out the parking brake cable by compressing the cable retainer with a 1/2 inch offset box wrench. Remove the bolts holding the parking brake cable and routing brackets to the axle trailing arm and if your car has antilock brakes, pull out the wheel speed sensor. Take out the bolts holding the disc brake adapter and spindle to the axle and afterward remove them both. If there is a watts link bell crank or stabilizer bar, remove them, place the axle on a transmission jack and take out the bolts securing the shock absorber. Detach the springs and isolators with the jack and write the position of the trailing arm brackets down. Remove the bolts joining the trailer arm, leading bracket and the axle. Check the axle for signs of damage, clean the fasteners with the correct torque and look for any worn-out welds or corroded bushings. While putting it together, attach the trailing arm forward brackets to the axle shaft and use thru-bolts to mount them from the outside in. Place the axle beam on a transmission jack, match the trailing arms with the marks from the templates and fit the axle bracket-to-body bolts, but don't tighten them yet. Fasten rubber isolators to the coil springs, put the springs on the axle spring perches and check their alignment. Place the jack to lift the springs into the brackets, after that bolt and tighten up the lower shock mounts. If you're using a rear stabilizer bar, attach the cushion retainers and tighten the bolts properly. After preparing the watts link bell crank, bolt it to the axle and place the spindle, seal and disc brake adapter. Before you tighten all, apply adhesive to the bolt threads. Attach the wheel speed sensor and related clips, direct the parking brake cable through the trailing arm and secure the cable and all of its brackets. Connect the parking brake cable to the disc brake adapter, insert the lever into the adapter as well and put back together the parking brake shoe assembly. Bring together the hub, bearing and spindle, install the new hub nut and tighten everything. Attach the brake rotor and caliper back together using the guide pin bolts, after that reattach the disc brake flex hose and wheel assembly by tightening the nuts of the wheel. Once the car is lowered, join the cables in the rear parking brake to the equalizer and check that everything is tight. Once done, unlock the automatic adjuster lockout slot. Drop the parking brake, move the cables using the lever, try the rear wheels to ensure they spin freely, reattach the battery, replace the air cleaner cover and check that pressing the brake pedal feels strong and steady before taking the car away. Then, tighten up the trailing arm to the mounting bracket pivot thru-bolts at the curb height and check that you need to do a rear wheel alignment.
