Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use appropriate jack stands for safety.

2. Replace Worn Shock Absorbers/Struts

Tools Required: Socket set, torque wrench, strut spring compressor.
Sub-steps:
1. Remove the wheel to access the suspension components.
2. Use a strut spring compressor to compress the spring on the strut assembly.
3. Remove the top strut nut and detach the strut from the steering knuckle.
4. Remove the strut assembly from the vehicle.
5. Install the new strut by reversing the removal steps and ensure all nuts are torqued to manufacturer specifications.

3. Replace Worn Bushings

Tools Required: Socket set, pry bar, rubber mallet.
Sub-steps:
1. Identify and remove the components attached to the bushings (e.g., control arms).
2. Use a pry bar to remove the old bushings from their mounts.
3. Press or hammer in new bushings, ensuring they are seated correctly.
4. Reattach the components and torque to specifications.

4. Inspect and Replace Wheel Bearings

Tools Required: Socket set, bearing puller, grease.
Sub-steps:
1. Remove the wheel and brake assembly for access to the hub.
2. Remove the axle nut and detach the hub from the steering knuckle.
3. Use a bearing puller to remove the old wheel bearing from the hub.
4. Press in the new wheel bearing and reassemble the hub, ensuring proper lubrication.
5. Reattach the hub to the steering knuckle and torque the axle nut to specifications.
