Inspect the control arms, bushings, and ball joints for wear; replace any damaged parts.
- Use a torque wrench to tighten new components to manufacturer specifications.
- Tools Required: Socket set, torque wrench, pry bar.

4. Check and Replace CV Joints

Remove the wheel and inspect the CV joint for damage.
If the boot is torn or the joint is worn, replace the CV axle.
- Tools Required: Axle puller, socket set.
Ensure proper lubrication is applied during reinstallation.

5. Inspect Wheel Bearings

Spin the wheel and listen for grinding noises; if present, replace the wheel bearing.
Remove the hub assembly and replace the bearing using a press tool.
- Tools Required: Bearing press, socket set.
