- If bushings are worn, remove the control arm bolts and replace the bushings.
- Reinstall and torque bolts to manufacturer specifications (consult service manual for exact torque values).

B. Ball Joints

Check for play:
- Use a jack to lift the suspension slightly and shake the wheel.
- If movement is detected, remove the ball joint from the control arm.
- Replace with a new ball joint and follow manufacturer torque specifications for installation.

C. CV Joints

Inspect for damage:
- Look for any tears in the CV boot.
- If damaged, remove the axle from the vehicle and replace the CV joint or the entire axle assembly.
- Torque the axle nut to the specified value.

D. Steering Rack

Check for looseness:
- Inspect mounting points of the steering rack.
