Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Damaged Suspension Components

Tools Required: Socket set, torque wrench, pry bar, jack and jack stands
Inspect shocks and struts for leaks or damage.
- If damaged, remove the old strut or shock by:
  1. Loosening the upper mounting bolts.
  2. Removing the lower bolts from the assembly.
  3. Installing the new shock/strut by reversing the removal steps, ensuring to torque bolts to manufacturer specifications.
Check control arms and bushings for wear.
- Replace any worn components by:
  1. Removing the bolts securing the control arm.
  2. Installing new bushings if necessary.
  3. Reinstalling the control arm and torquing to specifications.

3. Wheel Alignment Adjustment

Tools Required: Professional alignment tool
After replacing any components, perform a wheel alignment:
1. Position the vehicle on an alignment rack.
2. Adjust toe, camber, and caster settings to manufacturer specifications.
3. Test drive the vehicle post-alignment to ensure the vibration has been resolved.
