•Noise from the suspension when driving over bumps

Diagnostic Steps

1
Inspect strut assemblies for visible signs of oil leakage.
2
Check for any abnormal wear patterns on tires which may indicate strut failure.
3
Perform a bounce test by pushing down on each corner of the vehicle and observing rebound behavior.
4
Examine other suspension components for damage or wear that could be associated with strut failure.
5
Use an OBD-II scanner to check for related suspension fault codes, if applicable.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Safely elevate the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the strut assembly.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, spring compressor.

2. Remove the Strut Assembly

Loosen and remove the lug nuts from the wheel.
Remove the wheel to expose the strut assembly.
Disconnect the sway bar link from the strut to free the assembly.
Remove the lower strut mounting bolts using a socket.
Use a spring compressor to safely compress the coil spring on the strut.
Remove the top strut mount nuts under the hood to fully detach the strut assembly.

3. Replace or Rebuild Strut

If replacing, install the new strut assembly by reversing the removal steps.
If rebuilding, remove the coil spring from the old strut using a spring compressor and install it on the new strut.
Ensure all components (bushings, mounts) are in good condition and replace if necessary.

4. Reinstallation

Reinstall the strut assembly by securing the top mount nuts and lower mounting bolts, torquing them to the manufacturer’s specifications (refer to service manual for exact torque values).
Reattach the sway bar link.
Reinstall the wheel and torque the lug nuts to the specified value (typically 100-150 lb-ft).
Lower the vehicle from the jack stands.
