Cadillac 22868629 Rear Lower Control Arm Assembly

To remove the component, first loosen the wheel lug nuts, raise the vehicle, and securely support it on jackstands placed under the frame rails before removing the wheel. Next, disconnect the stabilizer bar link from the control arm and remove the shock absorber lower mounting fasteners. For 4WD models, remove the drive axle, and if working on a model with torsion bar front suspension, remove the torsion bar. Use rope or wire to support the upper control arm and steering knuckle from the top of the shock absorber. To disconnect the lower control arm from the steering knuckle, loosen the ball joint nut a few turns without removing it, then install a ball joint separator to break the ball joint loose from the knuckle; a hammer and drift can also be used if necessary. After removing the nut, take out the lower control arm pivot bolts and nuts, noting the installation direction, and pull the lower arm from its frame brackets. For installation, position the arm in the frame brackets and install the bolts and nuts without tightening them yet. Attach the ball joint to the steering knuckle, install a new nut, and tighten it to the specified torque. The remainder of the installation follows the reverse order of removal, ensuring all fasteners are tightened to the correct torque values. The pivot bolt nuts should be tightened with the vehicle at normal ride height, which can be done after lowering the vehicle or by simulating the height with a floor jack. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque. If working on a model with torsion bar front suspension, check and adjust the ride height, and have the front end alignment checked and adjusted if necessary.

This procedure applies to models with coil spring rear suspension only. Begin by loosening the rear wheel lug nuts, raising the rear of the vehicle, and securely supporting it on jackstands placed underneath the frame rails while blocking the front wheels to prevent rolling. Remove the wheel(s) and, if equipped with Autoride®, unbolt the height sensor linkage from the bracket on the trailing arm, ensuring not to change its adjustment or pry on it; pivot the linkage up and support it to avoid damage. Support the rear axle with a floor jack, then remove the nuts, washers, and bolts from each end of the trailing arm before taking out the arm. Inspect the bushings for any signs of deterioration; if replacement is necessary, consult a local auto parts store or dealer for availability and take the arm and bushings to a qualified repair facility for pressing. Installation follows the reverse order of removal, raising the rear axle to simulate normal ride height before tightening the fasteners to the specified torque. For the track bar, raise the rear of the vehicle and support it securely on jackstands, blocking the front wheels. Detach the parking brake cable from the clips on the arm, then remove the nuts and bolts from each end of the bar. After removing the bar, check the bushings for deterioration and follow the same procedure for replacement if needed. Reinstallation is the reverse of removal, ensuring to raise the rear axle to normal ride height before tightening the fasteners to the specified torque.

In order to take off the trailing arm, start by loosening the rear wheel lug nuts and raising the rear of the vehicle, supporting it securely on jackstands placed underneath the frame rails. Also, block the front wheels in order to prevent a rolling vehicle and remove the wheel(s). If equipped with Autoride, take out the linkage to height sensor from its bracket on trailing arm. The nuts, washers and bolts at each end of the trailing arm should be removed after supporting the rear axle using a floor jack. Remove it and check its bushings for signs of wear or damage. If you can get replacement bushings, just go with that option as you take it to have new ones pressed in while old ones are being pressed out. To put it back up there temporarily, raise the rear axle with a floor jack till you create an imitation of normal ride height then tighten down your fasteners based on torque specifications. In addition, if you want to remove your track bar then raise your car's rear side as well as secure this well using some heavy stands positioned beneath frame rails. Moreover here is also blocking off front wheels so that car does not roll away plus detach parking brake cable from clips on arms. The bar should be unfastened by removing bolts/nuts from both ends and finally pulling out whole element. Inspect these bushings which are in that bar looking for any signs indicating corrosion presence among them all respectively like shown below. On another note, buy new bushes and have those old one pressed out as well as fresh ones pushed into place together with rod itself at mechanics' place around instead where it is they will make sure that everything fit before staining yourself trying do everything alone without their help even if only repairing small things within vehicle hence do nothing but taking entire day removing such parts before bringing them over here either way since this would be much easier than what was initially thought especially when someone tried doing so alone. Raise the rear axle with a floor jack to simulate normal ride height, and tighten the fasteners using torque specifications on it as per my opinion.

To remove the upper control arm on a vehicle, first loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands. Remove the wheel and position a floor jack under the lower control arm to take the spring pressure off the upper control arm. Mark the relationship of the adjusting cams to the brackets on the frame and unbolt the brake hose/wheel speed sensor bracket from the upper control arm. If working on a 4WD model, remove the driveaxle. To disconnect the upper control arm from the steering knuckle, loosen the upper balljoint nut a few turns, install a puller or ball joint separator, and break the ball joint loose from the knuckle. Remove the nut and upper control arm pivot bolts and nuts, noting which way the bolts are installed. To install the new upper control arm, position the arm in the frame brackets and install the bolts and nuts, but don't tighten them yet. Attach the ball joint to the steering knuckle, install a new nut, and tighten it to the torque specifications. The remainder of installation is the reverse of removal. Make sure the marks made prior to disassembly are aligned, then tighten the nuts to the torque specifications. Finally, tighten the wheel lug nuts to the torque specifications and have the front-end alignment checked and, if necessary, adjusted.

For 4WD models, remove the driveaxle, although using a pickle fork type ball joint separator may eliminate the need for this step.

During installation of the track bar, the rear axle should be raised with a floor jack to simulate normal ride height.

Before removing the lower control arm, you should do the following: Disconnect the stabilizer bar link from the control arm. Remove the shock absorber lower mounting fasteners. If it's a 4WD model, remove the front driveaxle. If working on a model with torsion bar front suspension, remove the torsion bar. Use rope or wire to support the upper control arm and steering knuckle from the top of the shock absorber.

The initial steps to remove the upper control arm on a vehicle are as follows: Loosen the wheel lug nuts. Raise the front of the vehicle. Support the vehicle securely on jack stands. Remove the wheel.

To disconnect the lower control arm from the steering knuckle, follow these steps: Loosen the ball joint nut a few turns. Install a ball joint separator and break the ball joint loose from the knuckle. Remove the nut.

To disconnect the upper control arm from the steering knuckle, follow these steps:Loosen the upper ball joint nut a few turns.Install a puller or ball joint separator.Use the puller or separator to break the ball joint loose from the knuckle.Remove the nut and upper control arm pivot bolts and nuts, noting which way the bolts are installed.

After removing the trailing arm, you should check the bushings for signs of deterioration. If replacement bushings are available, you should take the arm to have the old ones pressed out and the new ones pressed in.

If the vehicle is equipped with Autoride, you should unbolt the height sensor linkage from the bracket on the trailing arm.
