A leaking front shock absorber on the Fiat 500 2008 causes excessive body movement and a failed MOT. The procedure involves removing the anti-roll bar drop link, the two lower hub bolts and the top mount nut before the strut and spring assembly can be removed.
A spring compressor is required to transfer the spring and top mount to the new shock absorber.
When You Need This Job
- Oily residue visible on the shock absorber body
- Excessive bouncing or poor body control
- Knocking from the front suspension over bumps
- MOT failure or advisory on shock absorber condition
Tools You'll Need
Step-by-Step Guide
Remove the wheel
Undo the 17mm wheel nuts and remove the front wheel to expose the shock absorber assembly.
Unclip the ABS sensor wire and brake hose
Unclip the ABS sensor wire from its holder on the shock body and unclip the brake hose. Move them out of the way so they do not get damaged when the shock is removed.
Remove the anti-roll bar drop link
Undo the drop link nut. If the ball joint spins use mole grips on the back of the link to hold it still.
Remove the two lower hub bolts
Two bolts pass through the bottom of the shock absorber into the hub. These may be corroded — use hand tools and take care with the threads. Clean them up with a wire brush before attempting removal.
Push the hub away and free the shock
With the lower bolts out push the hub forward slightly. The shock absorber can now be moved away from the hub.
Remove the top mount nut with a 19mm socket
With the car back on the ground locate the top of the strut tower in the engine bay. Undo the 19mm nut. The shock absorber assembly can now be lifted out from below.
Compress the spring and swap the shock
Clamp the spring in a spring compressor. With the spring compressed undo the top nut. Remove the top mount, collar and spring. Fit the new shock into the spring ensuring it locates in the bottom recess. Refit the top mount and new nut.
Refit in reverse order
Feed the new strut assembly back into the strut tower and start the top nut. Line up the lower mounting holes, insert the bolts and tighten. Refit the drop link. Refit all clips. Torque the top nut. Refit the wheel.
Torque Specifications
While the shock is out it costs very little to fit a new top mount. These wear at a similar rate to the shock absorber and save doing the job again.
