Parts for your 1999 Nissan Navara-Bump stops

1999 Nissan Navara bump stops — what they do and when to replace them

Based on the Nissan Navara D22 Workshop Manual (1997–2004) and the Nissan FAST electronic parts catalogue for D22 models, the 1999 Navara is fitted with suspension bump stops front and rear. The front independent torsion-bar setup uses jounce and rebound stoppers on the control arms, and the rear leaf-spring axle uses frame-mounted bump stops above the axle. So yes—bump stops are absolutely relevant on a 1999 Navara.

On a ’99 Navara, bump stops act as the last line of defence when the suspension compresses or extends to its limits. They cushion heavy hits, protect shocks and struts from bottoming out, stop tyres from fouling guards or chassis, and help keep CVs, leaf packs, and bodywork out of harm’s way. In day-to-day driving they rarely draw attention, but load the ute, tow a trailer, or drop into a rut off-road and they quietly save expensive parts.

As part of regular servicing, it’s worth giving the bump stops a proper look. Rubber hardens and cracks with age, and polyurethane can chunk or deform if it’s been belted. If a bump stop is missing, perished, or its bracket is loose, the Navara can clunk on big bumps, bottom out sooner, or feel harsh through the cab. That’s a cue to replace them—ideally in axle pairs so the suspension stays balanced.

Inspection is straightforward during a routine service: check the front control-arm stops and the rear frame stops for splits, tears, glazing, missing pieces, or metal-to-metal witness marks. Make sure brackets aren’t bent and fasteners are snug. Avoid petroleum-based sprays on rubber, a mild soapy clean or a silicone-safe product is the go.

Replacing them is a simple spanner job for most variants. Support the chassis safely, let the suspension hang to unload the stop, unbolt the old unit, clean the mounting face, and fit the new stop with fresh hardware if supplied. Tighten to the workshop manual spec, then set ride height and confirm bump-stop clearance matches the D22 spec after any torsion bar or spring adjustments. If the Navara has a lift, bigger tyres, or long-travel shocks, consider matched extended or progressive bump stops to control travel without a harsh hit—too-hard stops can feel jarring and stress mounts.

After fitting, road-test over speed humps and corrugations, then recheck fasteners. It’s a small job that pays off in comfort, control, and component life—especially for a hard-working D22.

• Common signs they need attention: sharp clunks on compression, visible cracks or missing chunks, uneven tyre contact on big hits, or shiny witness marks where parts have touched.
• Service tip: inspect every 10,000–15,000 km or whenever ride height or springs are changed.

Popular questions

Where are the bump stops on a 1999 Navara?
They sit on the front control arms (jounce and rebound stoppers in the torsion-bar IFS) and on the chassis rails above the rear axle tubes. If the ute has seen off-road work, they’re easy to spot—look for the rubber or polyurethane blocks where the arms or axle would make contact at full compression.

What are the symptoms of worn or missing bump stops?
Clunks over speed humps, a harsh “bang” on big dips, and signs of metal-to-metal contact are common. The ute might feel crashy when loaded or towing. Visually, you’ll see cracks, splits, or chunks missing, and sometimes bent brackets if they’ve been copping heavy hits.

Do lifted Navaras need different bump stops?
Often, yes. A suspension lift, heavier springs, or longer shocks can change travel and clearances. Extended or progressive bump stops help control compression, protect shocks and guards, and tame harsh bottoming. They should be matched to the shock stroke and ride height, then set up per the D22 workshop specs.
