Installation guide - Replacing lift supports (gas struts)
General guidance for this part type - always follow your device manual- Prop rod, broom handle or a helper
- Small flat screwdriver
- Replace both struts together so the lid lifts evenly.
- Never puncture or heat an old gas strut; recycle it.
- 1Prop the lid. Engine off. Open the hood, trunk or tailgate fully and prop it securely, since it will drop once a strut is removed.
- 2Release the old strut. Lift the small spring clip on each end socket slightly with a flat screwdriver (do not pull it out) and pull that end off its ball stud.
- 3Check orientation. Fit the new strut the same way round as the old one; most are fitted with the thin rod end pointing down.
- 4Fit the new strut. Press each end onto its ball stud until it snaps on. Replace the second strut the same way.
- 5Test. Remove the prop and open and close the lid a few times to check it holds and closes smoothly.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
