Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Worn Components

Inspect the Suspension
- Use a jack to lift the front of the vehicle and secure it on jack stands.
- Visually inspect control arms, bushings, and shocks for any visible signs of wear or damage.
Check the Tie Rod Ends and Ball Joints
- Grab the tie rod ends and ball joints and check for play; replace if excessive.
- Use a socket set to remove and replace any worn components.
Power Steering Fluid
- Check the power steering fluid level using the dipstick; add manufacturer-recommended fluid if needed.
- If fluid is low, inspect for leaks in the power steering system.
Inspect the Steering Rack
- Check for any leaks around the steering rack seals.
- If the rack is leaking or feels loose, consider replacing it.
Wheel Bearings
- Rotate each wheel by hand to check for roughness or noise; replace bearings if necessary.
- Use a torque wrench to ensure proper tightness during reassembly.
