Rear suspension setups vary a lot. Some cars have separate shocks and springs, while others combine them into a strut. This guide covers the most common UK setup where the rear spring and shock are separate (which is usually simpler than the front).
Rear springs can still be under tension, especially on multi-link or compact suspension setups. Never force components apart, and support the axle properly at all times.
New rear shocks
New rear springs (if replacing both)
Jack and axle stands
Wheel nut wrench
Socket set and spanners
Penetrating oil
Pry bar (helpful)
Torque wrench
Optional: spring compressor (only if design requires it)
Park on level ground.
Engage handbrake and select Park/gear.
Loosen wheel nuts slightly.
Jack up the rear and secure on axle stands.
Remove the wheels.
Place a jack under the rear axle or suspension arm.
This helps control movement when bolts are removed.
Rear shocks are usually bolted at:
Top mount (inside boot or under car body)
Bottom mount (axle or suspension arm)
Spray bolts with penetrating oil.
Undo the lower shock bolt first.
Move to the upper shock mount:
May require removing interior trim in the boot
Remove shock absorber completely.
Depending on design:
Lower the suspension arm slowly using the jack.
The spring will loosen as tension is released.
Remove the spring and rubber seats.
You may need a spring compressor to safely remove it.
Check:
Rubber spring seats (top and bottom)
Shock mounts and bushes
Rust or cracks in spring coils
Replace worn parts to avoid noise or uneven ride height.
Fit rubber seats correctly.
Position spring in correct orientation (ends must sit in grooves).
Slowly raise suspension arm with jack until spring is seated securely.
Position shock into place.
Fit upper mount first (loosely).
Align and fit lower bolt.
Tighten both ends to manufacturer torque specs.
Refit any interior boot trim (if removed).
Ensure all brackets and clips are secured.
Reinstall wheels.
Tighten wheel nuts by hand.
Lower vehicle to ground.
Torque wheel nuts in a star pattern.
Bounce rear of car to settle suspension.
Listen for knocking or creaking.
Check ride height is even side-to-side.
Take a slow test drive.
Always replace rear shocks in pairs.
Replace springs in pairs to maintain even ride height.
If bolts are heavily rusted, they may need heat or cutting tools.
New shocks may feel stiff at first—this is normal.
Never work under a car supported only by a jack.
Do not let the suspension hang freely without support.
If ride height looks uneven after installation, recheck spring seating immediately.
