Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings
- Check for cracks or excessive wear in the control arm bushings.
- If damaged, remove the bolts securing the control arm using a socket set.
- Replace the bushings as necessary.
Check CV Joints
- Inspect the CV joint boots for tears or grease leakage.
- If damaged, remove the axle nut with a socket and breaker bar, then pull the axle out from the hub.
- Replace the CV joint or the entire axle assembly if necessary.

3. Inspect Steering Linkage

Examine Tie Rod Ends
- Check for play by gripping the tie rod and moving it side to side.
- If worn, loosen the tie rod end nut and remove the tie rod from the steering knuckle.
- Replace with a new tie rod end and tighten to manufacturer specifications (typically around 30-40 ft-lbs).

4. Wheel Bearings and Struts

Inspect Wheel Bearings
- Spin the wheel to listen for grinding or roughness.
- If defective, remove the wheel and brake caliper, then extract the hub assembly to replace the wheel bearing.
Strut Inspection
- Check for signs of oil leakage around the struts.
- If leaking, replace the strut assembly by removing the strut mount bolts and lowering the assembly out.
