⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Ensure the vehicle is securely lifted and supported with jack stands before working under it.

Symptoms

•Grinding noise when accelerating or decelerating
•Noise when turning or navigating corners
•Vibration or shaking felt through the steering wheel
•Decreased braking performance or pulsation when braking
•Unusual wear on tires
•Check engine light may illuminate

Diagnostic Steps

1
Inspect the brake components for wear or damage, including pads, rotors, and calipers.
2
Check the wheel bearings for play or damage by lifting the vehicle and spinning the wheels.

Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Brake Inspection and Replacement

Sub-steps:
- Remove the wheel using a socket set.
- Inspect brake pads for thickness; replace if below manufacturer's specifications.
- Check brake rotors for scoring or warping; replace if necessary.
- Reassemble the wheel and lower the vehicle.

3. CV Joint and Axle Inspection

Sub-steps:
- Lift the vehicle securely using jack stands.
- Remove the wheel and visually inspect the CV joint boot for tears.
- If damaged, replace the CV joint or axle as follows:
  1. Remove the axle nut using a socket and breaker bar.
  2. Disconnect the lower control arm if necessary for clearance.
  3. Pull the axle out of the transmission and replace it with a new one.
- Reassemble all components.

4. Wheel Bearing Replacement (if necessary)

Sub-steps:
- Remove the affected wheel and brake components.
- Use a bearing puller to extract the old wheel bearing from the hub.
- Install the new wheel bearing with proper alignment and torque specifications.
- Reassemble the brake components and wheel.

5. Suspension Inspection and Repair

Sub-steps:
- Inspect struts and bushings for signs of wear.
- Replace struts if they show signs of leakage or damage.
