Solution

1. Preparation

Gather tools and parts needed for repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, power steering fluid
Remove the power steering fluid reservoir cap.
Use a funnel to check the fluid level; add fluid if necessary.
If fluid is dirty or contaminated, drain the old fluid and replace with new fluid as per manufacturer specifications.

3. Replace CV Joints (if damaged)

Tools Required: Socket set, axle puller, torque wrench
Lift the vehicle and remove the front wheels for better access.
Remove the axle nut using the socket set.
Detach the CV joint from the steering knuckle and slide it out of the transmission.
Install the new CV joint by sliding it back into the transmission and reattaching it to the steering knuckle.
Torque the axle nut according to manufacturer specifications.

4. Inspect and Replace Wheel Bearings (if worn)

Tools Required: Bearing puller, torque wrench, socket set
Remove the wheel and brake caliper for access to the hub.
Use a bearing puller to extract the wheel bearing from the hub assembly.
Install the new bearing, ensuring it is seated properly.
Reassemble the wheel and brake components, torquing to specifications.

5. Inspect and Replace Suspension Components (if needed)

Tools Required: Socket set, torque wrench
Inspect struts and bushings for wear.
If any components are damaged, remove the old parts and install new ones according to manufacturer specifications.
Ensure all bolts are torqued to the specified values.
