Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid pump, power steering fluid (refer to owner's manual for specifications), funnel.
Check the power steering fluid level; if low, top it up with the recommended fluid.
If the fluid is dirty or contaminated, drain the old fluid using a fluid pump and refill with fresh power steering fluid.

3. Replace Worn Steering Components

Tools Required: Socket set, torque wrench, wrenches, ball joint separator.
Remove the wheel to access the steering components.
If the tie rod ends or steering rack are found to be damaged, detach them using a ball joint separator, and replace with new components.
Torque all new components to manufacturer specifications.

4. Inspect and Replace CV Joints

Tools Required: Socket set, CV joint removal tool.
Remove the axle nut and detach the CV joint from the wheel hub.
Inspect the CV boot for tears and the joint for wear; if damaged, replace the CV joint.
Reassemble and ensure the axle nut is torqued to specifications.

5. Check and Replace Wheel Bearings (if needed)

Tools Required: Bearing puller, socket set, torque wrench.
Raise the vehicle and remove the wheel.
Use a bearing puller to remove the old bearing if play is detected.
Install the new wheel bearing and torque to specifications.
