Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Wear safety glasses and gloves while inspecting and replacing components.

Symptoms

•Popping or clunking noise when driving over bumps
•Noise during sharp turns or when braking
•Uneven tire wear
•Vehicle feels unstable or has a bouncy ride
•Visual inspection reveals damaged or worn suspension components

Diagnostic Steps

1
Inspect the suspension components visually for wear or damage, including struts, shocks, control arms, and bushings.
2
Check the mounting hardware for the suspension components to ensure they are tight and not damaged.
3
Perform a bounce test on the vehicle to assess shock absorber function; the vehicle should settle quickly after being bounced.
4
Lift the vehicle using a jack and inspect for play in the ball joints and tie rods.
5
If equipped, check the sway bar links for wear or looseness.

Solution

1. Preparation

Gather tools: socket set, torque wrench, jack and jack stands, pry bar, and lubricants.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the vehicle at the designated lift points.
Securely place jack stands under the vehicle for safety.

3. Inspect and Replace Suspension Components

Inspect struts/shocks: Check for leaks or physical damage.
- If damaged, remove by loosening the top mounting bolts under the hood and bottom bolts at the knuckle.
- Install new struts/shocks by reversing the removal steps and torque bolts to manufacturer specifications (often around 50-60 ft-lbs).
Check control arms and bushings: Look for cracks or excessive wear.
- If replacements are necessary, disconnect the lower ball joint and remove the control arm bolts.
- Replace with new parts and torque to specifications (typically 70-80 ft-lbs for the control arm bolts).

4. Sway Bar Link Replacement (if applicable)

Inspect sway bar links for wear. If they are worn:
- Remove the bolts securing the sway bar link to the sway bar and lower control arm.
- Install the new sway bar link and torque to manufacturer specifications (usually around 30-40 ft-lbs).

5. Reassemble and Lower Vehicle

Double-check all connections and components to ensure tightness.
Carefully lower the vehicle off the jack stands using the jack.
