Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is turned off.
Gather necessary tools and parts.
Disconnect the battery for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, refill with the recommended fluid (consult owner's manual for specifications).
Start the vehicle and turn the steering wheel from lock to lock to bleed any air from the system.

3. Inspect and Replace CV Joints (if necessary)

Lift the front of the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the CV joint.
Inspect the CV boot for tears or grease leakage.
If damaged, remove the CV joint by unscrewing the bolts connecting it to the hub and the transmission.
Replace with a new CV joint and ensure to apply the correct torque specifications when reassembling.

4. Examine and Replace Suspension Components (if necessary)

Inspect all suspension components, including control arms, bushings, and struts.
If any components are worn or damaged, remove the affected part using appropriate tools (e.g., socket set, wrenches).
Replace with OEM or high-quality aftermarket parts.
Reassemble and ensure all bolts are torqued to specifications.

5. Brake Inspection and Replacement (if necessary)

Check brake pads for wear; if they are worn down, remove the caliper using a socket set.
Replace pads with new ones and inspect the rotors for damage. If warped, replace rotors as well.
Reassemble the brake system and ensure proper torque specifications are followed.
