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.

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 finalize the installation of the upper control arm, follow these steps: Ensure that the marks made prior to disassembly are aligned. Tighten the nuts on the control arm to the torque specifications. Tighten the wheel lug nuts to the torque specifications. Have the front-end alignment checked and, if necessary, adjusted.

The initial steps to remove and install a lower control arm on a vehicle are as follows: Loosen the wheel lug nuts. Raise the vehicle. Support it securely on jackstands placed under the frame rails.

After disconnecting the ball joint, proceed with these steps: Remove the lower control arm pivot bolts and nuts, noting the orientation of the bolts and, on 4WD models, how the washers are installed. Pull the lower arm from its frame brackets.
