Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure with a tire gauge; inflate to recommended PSI if low.
2. Inspect each tire for visible damage or uneven wear patterns.
3. Replace any damaged tires with new ones of the same size and specifications.
Tools Required: Tire pressure gauge, tire changing tools (jack, lug wrench).

3. Wheel Alignment

Sub-steps:
1. Use an alignment machine or take the vehicle to a professional alignment shop.
2. Adjust camber, toe, and caster as necessary to meet manufacturer specifications.
Tools Required: Alignment machine (if performing in-house).

4. Suspension Component Inspection and Replacement

Sub-steps:
1. Inspect struts/shocks for leakage or damage; replace if necessary.
2. Check control arms, bushings, and sway bar links for wear; replace any faulty components.
3. Torque all suspension bolts to specified values as per the repair manual.
Tools Required: Socket set, torque wrench.

5. Test Drive

Sub-steps:
1. Reconnect the battery if it was disconnected.
2. Test drive the vehicle over various road conditions to ensure the rough ride has been resolved.
Safety Warnings: Ensure all tools and equipment are cleared from the vehicle before test driving.
