Parts for your 2017 Nissan Navara-Bump stops

2017 Nissan Navara bump-stops: what they do and when to replace them

Based on Nissan’s factory service information for the D23/NP300 platform and the official parts catalogue, the 2017 Nissan Navara is fitted with bump stops (also called jounce bumpers) at both ends. Workshop diagrams show front bump stops integrated with the front damper assemblies, and rear bump stops mounted to the chassis above the axle on coil-sprung and leaf-sprung variants alike. Aftermarket catalogues for the 2015–2019 Navara also list direct-replacement and upgraded bump stops, further confirming their use on this model.

On a 2017 Navara, bump stops act as the final cushion when the suspension compresses hard—think big potholes, corrugations, or a loaded tray hitting a dip. They prevent metal-to-metal contact, protect shocks, arms and chassis mounts, and add a progressive ramp-up in spring rate so the ute doesn’t slam into its limits. They also help keep handling tidy when towing, carrying tools, or heading off-road.

As part of regular servicing, it’s smart for owners to have the bump stops inspected. Rubber and microcellular polyurethane age with heat, UV and mud, they can crack, go chalky, or oil-soak if a shock is leaking. Front bump stops on the Navara are inside the front coilover assembly, so they’re commonly replaced when front struts are serviced. Rear stops are external and usually bolt to the chassis, making inspection and replacement straightforward.

• Check for cracks, splits, missing chunks, or collapsed/over-compressed stops.
• Listen for clunks or harsh bottoming on big bumps—often a giveaway the stops are perished or missing.
• After lifting, GVM upgrades, or heavy towing use, consider taller or progressive-rate replacements to maintain correct up-travel.

If replacement’s due, doing both sides at the same end keeps behaviour even. Genuine-equivalent rubber keeps the OE feel, while quality polyurethane or hydraulic-style upgrades can sharpen control with loads. For front replacements, expect strut removal and reassembly, a wheel alignment is a good idea afterwards. For the rear, the job is typically bolt-off/bolt-on, followed by a quick clearance check at full droop and near-full compression. Keeping the stops clean, checking them every 10,000–15,000 km or annually, and addressing any shock leaks early will help the Navara ride quietly and protect the expensive bits when the going gets rough.

FAQs

Do all 2017 Navara models have bump stops?
Yes. Nissan’s service literature and parts listings show front jounce bumpers in the damper assemblies and rear bump stops on the chassis across coil- and leaf-sprung variants. Whether it’s a workhorse cab-chassis or a dual-cab, the stops are part of the suspension’s safety net.

How often should 2017 Navara bump stops be replaced?
There’s no fixed interval. They’re replaced on condition—cracked, squashed, oil-soaked, or missing. With regular on-road use they can last years, frequent towing, off-roading, or heat exposure can shorten that. A quick look at each service keeps surprises away.

Are upgraded bump stops worth it for towing or a lift?
Often, yes. Progressive polyurethane or hydraulic-style stops can add control near full compression, helping with sag and harsh hits under load. If the Navara has a lift or GVM upgrade, matching bump stop height and travel to the new setup protects shocks and prevents binding.
