Affected Component

Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a lifted vehicle.
•Allow the vehicle to cool before handling any components that may be hot from use.

Symptoms

•Noticeable shaking or vibration when driving over bumps
•Poor ride comfort and handling
•Increased noise from the suspension system
•Uneven tire wear
•Possible alignment issues

Diagnostic Steps

1
Inspect the suspension components visually for damage or wear, including shocks, struts, and control arms.
2
Check the tire pressure and inspect for any bulges or uneven wear patterns.
3
Perform a bounce test on each corner of the vehicle to assess shock absorber functionality.
4
Inspect the vehicle's alignment using a professional alignment tool.
5
Examine the chassis for loose bolts or components, particularly in the suspension system.
6
Test drive the vehicle over bumps while observing for abnormal sounds or continued shaking.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves during the repair process.

2. Inspect Suspension Components

Sub-steps:
- Use a jack and jack stands to lift the vehicle safely.
- Remove the wheels for easier access to the suspension components.
- Visually inspect shocks and struts for leaks, dents, or signs of wear.
- Check control arms and bushings for cracks or deterioration.
Tools Required: Jack, jack stands, socket set

3. Replace Worn Shocks/Struts (if applicable)

Sub-steps:
- Remove the bolts securing the shock absorbers/struts to the vehicle using a socket set.
- Carefully detach the shock from its mounts.
- Install the new shock/strut by reversing the removal process.
- Torque the mounting bolts to manufacturer specifications (check the owner’s manual for specific torque values).
Tools Required: Socket set, torque wrench
Parts Required: New shocks/struts (specific to Ford F-150 model and year)

4. Check and Adjust Wheel Alignment

Sub-steps:
- After replacing shocks/struts, use an alignment tool to measure the alignment angles.
- Adjust as necessary to bring the vehicle back into manufacturer specifications.
- Test the alignment readings and confirm they are within tolerance.
Tools Required: Wheel alignment tool
Parts Required: Alignment specifications (reference manual)

5. Reassemble and Test

Sub-steps:
- Reinstall the wheels and lower the vehicle.
- Tighten all wheel nuts to the specified torque.
- Conduct a test drive to ensure that the shaking has been resolved.
Tools Required: Torque wrench
