Tools Required: Socket set, torque wrench, pry bar.
Lift the front of the vehicle and secure it with jack stands.
Remove the wheels to access the steering linkage.
Inspect the tie rod ends and ball joints for play or wear. Replace if necessary.
Tighten any loose fasteners to the manufacturer’s torque specifications.

4. Inspect CV Joints

Tools Required: Jack stands, socket set.
Inspect the CV joint boots for tears and the joints for wear.
If damage is found, replace the CV axle assembly.
Ensure that the new CV axle is properly lubricated and installed to specifications.

5. Check Wheel Bearings

Tools Required: Wheel bearing grease, socket set, torque wrench.
Rotate the wheel by hand to feel for roughness or grinding.
If the bearings are worn, remove the hub assembly and replace the bearings.
Repack the new bearings with grease and torque to specifications.
