•Allow the vehicle to cool before inspecting the brakes.

Symptoms

•Popping or clicking noise when turning or driving straight
•Noise increases with vehicle speed
•Vibration felt through the steering wheel
•Uneven tire wear
•Possible clunking noise over bumps

Diagnostic Steps

Inspect the tires for signs of uneven wear and check for any damage or debris lodged in the tread.
2
Perform a visual inspection of the suspension components (control arms, bushings, struts) for any visible signs of wear or damage.
3
Check the wheel bearings by lifting the vehicle and spinning the wheels to listen for grinding or roughness.
4
Examine the CV joints and boots for any cracks or leaks, and check for any excessive play in the joints.
5
Conduct a road test to replicate the noise while turning and driving to determine if it changes with steering input.

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is in "Park" (automatic) or neutral (manual).

2. Inspect and Replace Tires (if needed)

Sub-steps:
1. Remove the wheel covers or lug nut covers, if applicable.
2. Loosen the lug nuts slightly while the vehicle is on the ground.
3. Jack up the vehicle and support it with jack stands.
4. Remove the wheel and inspect for damage or uneven wear.
5. Replace the tire if damage is found or if uneven wear is excessive.

3. Inspect and Replace Suspension Components (if needed)

Sub-steps:
1. Inspect control arms and struts for wear.
2. If damaged, remove the affected component:
  - Remove mounting bolts using a socket set.
  - Use a suspension tool to disconnect the component from the chassis.
3. Install the new component:
  - Position the new part and hand-tighten the bolts.
  - Torque the bolts to the manufacturer’s specifications.
4. Reassemble any components that were removed.

4. Inspect and Replace CV Joints (if needed)

Sub-steps:
1. Lift the vehicle and remove the wheel for access to the axle.
2. Inspect the CV joint boot for cracks or grease leakage.
3. If damaged, remove the axle:
  - Unscrew the axle nut and remove it.
  - Detach the axle from the transmission and hub.
4. Install a new CV axle:
  - Align the axle and push it into the hub.
  - Secure with the axle nut and torque to specifications.

5. Inspect and Replace Wheel Bearings (if needed)

Sub-steps:
1. With the wheel removed, check for play in the hub assembly.
2. If wear is detected, remove the hub assembly:
  - Unscrew and remove the brake caliper and rotor.
  - Detach the hub assembly from the steering knuckle.
3. Install new wheel bearings:
  - Press the new bearing into the hub.
  - Reassemble the hub and reinstall the brake components.
