Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety glasses and gloves should be worn.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir for level and condition.
If the fluid is low or contaminated, drain the old fluid and refill with manufacturer-recommended fluid.

3. Replace Worn CV Joint or Axle

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the CV joint.
Disconnect the CV joint from the wheel hub and the transmission.
Install the new CV joint or axle by reversing the removal steps. Torque the axle nut to the manufacturer specification.

4. Replace Wheel Bearings (if applicable)

Remove the wheel and brake caliper.
Remove the brake rotor to access the wheel bearing.
Using a bearing puller, extract the old bearing and install the new one.
Ensure the new bearing is properly seated and reassemble components in reverse order.

5. Tighten or Replace Loose Suspension Components

Inspect all suspension bolts and nuts for tightness.
If any components are damaged, replace them with new parts.
Torque all bolts to the manufacturer’s specifications.
