Parts for your 2018 Nissan Serena-Bump stops

2018 Nissan Serena bump-stops

Technical documentation confirms the 2018 Nissan Serena (C27, including e-POWER) is fitted with bump-stops. Nissan’s Electronic Service Manual for the C27 shows a “bound bumper” within the front MacPherson strut assembly in the Front Suspension (FSU) exploded view, and a bump stop/bound bumper associated with the rear shock in the Rear Suspension (RSU) section. Nissan’s parts catalogue (FAST), suspension groups 540/550, also lists these components for C27 Serena variants. These sources establish that bump-stops are relevant and used on this model.

On the 2018 Serena, the bump-stops (also called bound bumpers or jounce bumpers) are small, dense rubber or microcellular polyurethane pieces that sit inside the front struts and on the rear shocks. Their job is to gently catch the suspension at the end of its travel so the vehicle doesn’t smack metal-on-metal over big hits, speed humps, driveway entries, or when heavily loaded. By cushioning the last bit of compression, they help keep the ride quiet and controlled, protect the struts and shocks from damage, and prevent the tyres from fouling the body under hard compression. They also add a progressive feel near full bump, which steadies the van when it’s carrying kids, gear, or doing airport runs.

For servicing, bump-stops aren’t a set-interval replacement, they’re inspected and replaced on condition. A technician will check them whenever the Serena has front struts or rear shocks out, or during a suspension inspection. Signs they’re due include cracking, chunks missing, perishing, or oil-soaked rubber (often from a leaking damper). A torn or slipped dust boot is a red flag too, because UV and road grime will quickly chew through the bump-stop underneath.

Best practice is to replace bump-stops alongside new struts/shocks, or whenever they’re damaged. It’s inexpensive insurance against bottoming-out that can bend piston rods, hammer top mounts, and create clunks. If the Serena sits low, tows, or spends life on corrugated roads, fresh bump-stops and intact boots make a noticeable difference in cabin comfort and how quietly it takes a hit. When servicing the fronts, proper spring compression and following the Nissan ESM torque specs are essential. Go with quality OEM-equivalent parts and keep an eye on tyre wear and ride height after any suspension work to ensure the bump-stops engage only when they’re meant to—right at the end of travel.

How do you know if the 2018 Serena’s bump-stops need replacing?

Look for thumps over speed humps, harsh bottoming when loaded, or visible cracks and missing chunks on the stops when the struts/shocks are out. Oil on the stop or a torn dust boot is a cue to replace.

Do new shocks or struts for a Serena come with bump-stops?

Sometimes. Many rear shocks include them, front MacPherson struts often require separate bound bumpers and boots. Always check the kit contents or parts catalogue before ordering.

Is it OK to drive if a bump-stop is perished or missing?

It’ll drive, but it’s not wise. Without a healthy bump-stop, hard hits can bottom the suspension, damaging struts, mounts, and even body brackets. Replace sooner rather than later.
