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.
