Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery to avoid electrical shorts.

2. Inspect and Replace Power Steering Fluid

Tools Required: Socket set, funnel, fluid catch pan
Locate the power steering reservoir and remove the cap.
Check the fluid level and condition; if it's dark or contaminated, proceed to replace it.
Using the fluid catch pan, drain the old fluid completely and dispose of it properly.
Refill the reservoir with the manufacturer-recommended power steering fluid, ensuring it is at the proper level.

3. Inspect and Replace Worn Suspension Components

Tools Required: Jack and jack stands, socket set, torque wrench
Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the control arms, bushings, and tie rod ends for wear or damage.
If any components are worn, remove them using the socket set and replace with OEM or high-quality aftermarket parts.
Torque all new fasteners to the manufacturer's specifications.

4. Check and Replace CV Joints if Necessary

Tools Required: Socket set, CV joint puller (if needed)
Inspect the CV joints for any tears in the rubber boot or signs of grease leakage.
If damaged, remove the affected CV joint from the axle and replace it with a new one.
Ensure all clips and fasteners are properly secured and torque them to specifications.
