Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
If necessary, disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Damaged CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint grease
Sub-steps:
1. Remove the wheel on the affected side using a socket set.
2. Inspect the CV joint boot for tears; if the boot is damaged, replace the entire CV joint.
3. If replacing, remove the axle nut and disconnect the lower control arm if necessary.
4. Pull the CV axle out of the transmission and replace it with a new CV joint assembly, ensuring the new boot is properly installed.
5. Reassemble all parts, torquing the axle nut to manufacturer specifications.

3. Inspect and Replace Sway Bar Links

Tools Required: Wrench set, socket set
Sub-steps:
1. Locate the sway bar links and check for any visible damage or play.
2. Use a wrench and socket to remove the sway bar link from the sway bar and control arm.
3. Install new sway bar links, ensuring they are tightened to the manufacturer's torque specifications.

4. Wheel Bearing Inspection and Replacement (if necessary)

Tools Required: Bearing puller, socket set, torque wrench
Sub-steps:
1. Rotate the wheel and listen for grinding noises indicating bearing failure.
2. If necessary, remove the brake caliper and rotor to access the wheel bearing.
3. Use a bearing puller to remove the old bearing and install a new bearing in the hub.
4. Reassemble the brake components and wheel, ensuring all fasteners are torqued to specifications.
