In case of damage to the subframe or if a pressed-in bushing is worn, remove the subframe by taking out the complete axle assembly. Begin by raising the vehicle and removing the rear wheels, followed by the removal of air springs. Next, take out the exhaust system and exhaust heat shield, then detach the driveshaft from the differential, using stiff wire to hang the driveshaft from the vehicle. Remove the brake calipers and brake discs, ensuring to hang the calipers aside with stiff wire without disconnecting the brake fluid hoses. Remove the left and right ABS wheel speed sensors from the wheel bearing carriers and disconnect the parking brake cables from the brake shoe expanders. Remove the suspension level sensor connector and detach the vent line from the rear differential. Remove the shock absorber and support the subframe from below using appropriate special tools. Take out the four rear suspension subframe mounting bolts and carefully lower the rear suspension subframe away from the body. For installation, jack the subframe into position, install and tighten the mounting bolts, and replace the stop plates in their original position. The remainder of the installation follows the reverse order of removal, with attention to tightening suspension arms and shock absorber fasteners to final torque only after the vehicle is lowered and the suspension has settled, activating and filling the air suspension, adjusting the emergency brake, and having the car professionally aligned upon completion.
