⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely supported on jack stands before working underneath.
•Disconnect the battery before starting work on electrical components.

Symptoms

•Excessive bouncing after hitting bumps
•Uneven tire wear
•Vehicle leans during cornering
•Difficulty maintaining control on rough roads
•Visible fluid leakage from struts
•Noise from struts when driving over bumps (clunking or knocking sounds)

Diagnostic Steps

1
Conduct a visual inspection of the struts for any signs of fluid leakage or physical damage.
2
Perform a bounce test by pushing down on each corner of the vehicle and observing how quickly it returns to the resting position.
3
Check for uneven tire wear patterns which could indicate poor strut performance.
4
Inspect the vehicle during a drive for any unusual noises or handling issues, especially when turning or on uneven surfaces.
5
Use a jack to lift the vehicle and check for play in the strut mounts and bushings by attempting to move them side to side.

Solution

Solution

1. Preparation

Gather tools and parts required for replacement.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the struts.

3. Remove Old Struts

Detach the brake line and ABS sensor wire from the strut (if applicable).
Unbolt the strut from the steering knuckle using a socket set; typically, 17mm or 19mm bolts.
Remove the upper strut mount bolts located in the engine bay or under the hood, usually requiring a 13mm or 15mm socket.
Carefully pull the strut assembly out of the mount and remove it from the vehicle.

4. Install New Struts

Position the new strut into place in the strut mount.
Secure the upper strut mount bolts with the specified torque (consult manufacturer specifications, commonly around 30-40 Nm).
Attach the strut to the steering knuckle and tighten the bolts to the manufacturer’s torque specs.
Reconnect the brake line and ABS sensor wire to ensure proper function.

5. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Reconnect the battery.
