Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and a pry bar.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Worn Components

Control Arms and Bushings:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the suspension components.
3. Use a pry bar to check for play in the control arm bushings; replace if worn or damaged.
4. Remove the control arms by unscrewing the bolts using a socket set. Torque specifications for reinstallation: 80 Nm (59 lb-ft).
5. Install new control arms and bushings, ensuring they are properly seated.
Steering Linkage and Tie Rod Ends:
1. Inspect the tie rod ends for any signs of wear or looseness.
2. If necessary, disconnect the tie rod end from the steering knuckle using a socket set.
3. Replace the tie rod end if it shows any signs of damage (torque for reinstallation: 45 Nm (33 lb-ft)).
4. Reconnect the tie rod and ensure proper alignment.

3. Wheel Bearing Inspection and Replacement

Spin the wheel to check for any grinding or roughness.
If the wheel bearing is faulty, remove the brake caliper and rotor to access the bearing.
Use a bearing puller to remove the old bearing and install a new one.
Reinstall the rotor and caliper, ensuring all bolts are torqued to specifications.
