Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues during the repair.

2. Inspect and Replace Struts/Shocks

Tools Required: Socket set, torque wrench, spring compressor, jack stands, and a multimeter.
Sub-steps:
1. Raise the vehicle using a hydraulic jack and secure it on jack stands.
2. Remove the wheels to access the suspension components.
3. Use a spring compressor to safely compress the coil spring if replacing struts.
4. Unbolt the strut/shock assembly from the top mount and lower control arm.
5. Replace the old strut/shock with a new one, ensuring it is properly seated.
6. Reassemble the suspension components and torque all bolts to manufacturer specifications.

3. Inspect and Replace Bushings

Tools Required: Socket set, pry bar, and a torque wrench.
Sub-steps:
1. Check all suspension bushings for signs of wear or deterioration.
2. If worn, remove the affected bushings using a pry bar and socket set.
3. Install new bushings, ensuring they are properly aligned and seated.
4. Torque all mounting bolts to the specified values.

4. Tire Inspection and Replacement

Tools Required: Tire pressure gauge and a tire changer (if replacing tires).
Sub-steps:
1. Check all tires for proper pressure and tread wear.
2. If any tire shows abnormal wear or is out of specification, replace it with a new tire.
3. Ensure all tires are balanced after installation.
