2. Inspect and Replace Steering Components

Inspect Steering Linkage:
- Remove any protective covers to access the steering components.
- Check for wear or play in the tie rod ends and the steering rack.
Replace Worn Components:
- If any tie rod ends are worn, mark their position for alignment purposes, then remove them using a socket set.
- Install new tie rod ends, ensuring they are torqued to the manufacturer's specifications (typically around 40-50 Nm).

3. Inspect and Replace Strut Mounts and Bushings

Remove Front Struts:
- Lift the front of the vehicle and secure it on jack stands.
- Remove the wheel to access the strut assembly.
- Disconnect the strut from the lower control arm and upper mount.
Replace Strut Mounts:
- Remove the upper strut mount using a socket set.
- Install the new strut mount, tightening to specified torque (usually around 23-30 Nm).

4. Inspect and Replace Control Arms and Ball Joints

Check Control Arm and Ball Joints:
- Inspect the control arms for cracks or excessive wear.
- Check ball joints for play and ensure they are not leaking grease.
Replace if Necessary:
- Remove the control arm bolts and disconnect the ball joint from the steering knuckle.
