Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down if it has been recently driven.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Visually inspect control arm bushings for cracks or separation.
- If damaged, use a socket set to remove the control arm bolts and replace the bushings or control arm as necessary.
Check CV Joints:
- Lift the front of the vehicle using a jack and secure it with jack stands.
- Spin the front wheels and listen for noises while inspecting the CV joints for tears in the boot or grease leakage.
- If damaged, remove the axle nut and replace the CV joint or axle.

3. Check Steering Components

Inspect Steering Rack and Tie Rods:
- With the vehicle lifted, grasp the tie rods and check for lateral play.
- If play is detected, remove the nuts securing the tie rod end and replace it with a new part.
Engine Mount Inspection:
- Check the engine mounts for any signs of wear or cracking.
- If worn, use a socket set to remove the engine mount bolts and replace the mounts.

4. Reassemble and Lower Vehicle

After replacing any worn or damaged components, ensure all bolts are torqued to manufacturer specifications.
Reinstall any shields or covers that were removed during inspection.
Lower the vehicle and remove the jack stands.
