Diagnostic Steps

2
Check for any visible leaks around the power steering system.
3
Examine the CV joints and boots for signs of damage or wear.
4
Inspect the wheel bearings for play or roughness.

Solution

1. Preparation

Gather tools and materials:
- Jack and jack stands
- Socket set
- Torque wrench
- Screwdrivers
- Replacement parts (if needed)
Ensure the vehicle is on a flat surface and the engine is turned off.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level and color. If it's low or dirty, proceed to replace it.
3. Use a turkey baster or suction pump to remove old fluid from the reservoir.
4. Refill with the manufacturer-recommended power steering fluid (Toyota ATF or equivalent).
5. Start the engine and turn the steering wheel from lock to lock to purge air from the system.

3. Check and Replace CV Joints

Sub-steps:
1. Lift the front of the vehicle and secure it with jack stands.
2. Remove the wheel to access the CV joint.
3. Inspect the CV boot for tears or leaks. If damaged, replace the CV axle.
4. To replace, remove the axle nut and any retaining clips, then pull the axle out of the transmission.
5. Install the new CV axle, ensuring it clicks into place in the transmission. Torque the axle nut to the manufacturer's specification (usually around 150 ft-lbs).

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. With the wheel removed, grasp the wheel hub and check for excessive play or roughness.
2. If the bearing is faulty, remove the brake caliper and rotor to access the hub.
3. Remove the hub assembly, typically held in place by bolts and the axle nut.
4. Replace the wheel bearing with a new one and reassemble the hub. Torque all bolts to the specified values.
