On 1996 and earlier models (and 1997 Olds), the strut cartridge can be replaced with the strut and spring assembly installed in the vehicle, eliminating the need to remove and disassemble the assembly unless there is damage to the spring, seats, or strut/knuckle components. For 1997 and later models (except Olds), the entire strut assembly must be removed and replaced if wear or damage occurs. To begin removal, loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands while applying the parking brake and blocking the rear wheels. Remove the wheel and mark the position of the strut mount cover to the strut tower before removing the nuts. On 1997 and later models, remove the strut to knuckle bolts and take out the strut, being careful not to overextend the CV joint or stretch the brake hose, and support the control arm if necessary. For 1996 and earlier models, separate the tie-rod end from the steering arm. Next, remove the brake caliper, bracket, and disc, hanging the caliper out of the way, and secure the ABS sensor if applicable. Remove the hub and wheel bearing bolts, then separate the balljoint from the lower control arm, taking care not to overextend the inner CV joint or stretch the brake hose. Remove the driveaxle, support the strut and spring assembly with one hand, and remove the three strut mounting nuts to take the assembly out through the fenderwell. Inspect the strut body for leaks, dents, cracks, and other damage, check the coil spring for chips and cracks, and inspect the knuckle/strut for corrosion or bending. If any wear or damage requires removing the coil spring, take the assembly to a dealer or equipped shop for repair. For installation, slide the strut assembly into the fenderwell, align the marks, and install the strut cover, then insert the three upper mounting studs through the shock tower holes. Once the studs protrude, install the strut cover to the marked position and secure it with nuts. On 1997 and later models, install the strut-to-knuckle bolts and tighten all strut mounting bolts to the specified torque. For 1996 and earlier models, install the driveaxle, connect the lower balljoint to the control arm, and tighten the nut with a new cotter pin. Install the hub and brake components, then install the tie-rod end in the steering arm and tighten the castellated nut with a new cotter pin. Finally, install the wheel, lower the vehicle, tighten the lug nuts, and ensure the three upper mounting nuts are also tightened to the specified torque.
