⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle to prevent injury.
•Allow the vehicle to cool before inspecting or working on the suspension system.

Symptoms

•Unusual bounce or sway during driving
•Increased noise from the suspension system, such as clunking or rattling
•Uneven tire wear
•Vehicle leaning or sagging on one side
•Fluid spots or stains under the vehicle where shocks are located

Diagnostic Steps

1
Perform a visual inspection of the shock absorbers for any signs of oil leakage or dampness.
2
Check for physical damage to the shock absorber, such as dents or bends.
3
Press down on each corner of the vehicle to observe how quickly it rebounds; excessive bouncing indicates potential shock failure.
4
Inspect the mounting hardware for any signs of looseness or wear.
5
Look for signs of fluid on the shock housing, indicating a leak.

Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Clean cloths or paper towels
Raise the vehicle using the jack and secure it with jack stands to ensure safety.

2. Visual Inspection

Use a flashlight to examine the shock absorbers closely.
Wipe the shock housing with a clean cloth to remove dirt and check for any fresh oil marks.
Inspect the area around the seals and joints for any signs of leakage.

3. Testing Shock Absorber Performance

Stand at one corner of the vehicle and apply your weight to push down on the rear or front bumper.
Release quickly and observe the shock's response; it should rebound smoothly without excessive bouncing.
Repeat this for each corner of the vehicle.

4. Remove and Replace (if necessary)

If leaks are confirmed, proceed with replacing the shock absorbers.
Tools Required:
- Socket set
- Torque wrench
- Spring compressor (if replacing strut assemblies)
Follow manufacturer guidelines for the specific torque values for shock mounting bolts.
After installation, ensure to properly torque all connections according to specifications.
