2. Inspect and Replace CV Joint Boots

Raise the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the front wheel.
Examine CV Joint Boots: Inspect the outer CV joint boots for tears or leaks. If damaged, proceed to replace.
Remove the CV Joint: Disconnect the axle from the wheel hub and the transmission using appropriate tools. Note the torque specifications for reinstallation.
Replace the Boot: Remove the old boot and install a new one, ensuring to grease the joint adequately.
Reassemble: Reinstall the CV joint and wheel, tightening bolts to the specified torque values.

3. Inspect and Replace Suspension Components

Check Control Arms and Bushings: Visually inspect the control arms and bushings for wear or damage.
Replace Worn Parts: If any components are found to be worn, use a socket set to remove and replace them with OEM or quality aftermarket parts.
Reassemble: Reinstall any removed components, ensuring all bolts are torqued to manufacturer specifications.

4. Check Steering Linkage

Inspect Steering Components: Look for any loose or damaged parts in the steering linkage, including tie rods.
Tighten or Replace: Tighten any loose bolts and replace any damaged components as necessary.
