  Q: How to Remove and Install Steering Knuckle on Buick LaCrosse?

  A: Removal begins with loosening the driveaxle/hub nut and wheel lug nuts, raising the front of the vehicle on jackstands, and removing the wheel. The hub and bearing assembly is removed, and the strut-to-knuckle nuts are loosened, followed by the disconnection of the tie-rod end and balljoint from the steering knuckle. The ABS wheel speed sensor electrical connector and ABS wire harness (if applicable) are detached, and the steering knuckle is separated from the strut. During installation, the knuckle is guided into the strut mounting flange, and the driveaxle is inserted along with the hub and bearing assembly. The Control Arm ball stud is attached to the steering knuckle, and the tie-rod is connected and tightened to torque specifications. The steering knuckle is aligned using the marks on the strut flange, and all nuts and bolts are tightened to their specified torque values. Install the electrical connector for the ABS wheel speed sensor, then the brake disc, caliper mounting bracket, and caliper. Install the wheel, lower the vehicle, and tighten the lug and driveaxle/hub nuts to the torque specifications.
