Parts for your 1999 Nissan Pulsar-Bump stops

1999 Nissan Pulsar bump-stops: what they do and when to replace them

The 1999 Nissan Pulsar (N15 series) is fitted with bump-stops from factory. Technical references that specify them include the Nissan N15 Factory Service Manual (Front Suspension: MacPherson strut with “bound bumper”, Rear Suspension: coil/beam layout with “spring bumper”), Gregory’s Service and Repair Manual for Nissan Pulsar N14/N15 (1991–2000), and Nissan’s electronic parts catalog listings for front strut bumpers and rear bump rubbers. These sources confirm the Pulsar uses bump-stops on both ends—integrated on the front strut under the dust boot, and as bump rubbers on the rear suspension.

On this Pulsar, bump-stops act like compact safety cushions. They’re small, dense foam or elastomer blocks that come into play only at the end of suspension travel. Their main jobs are to prevent the shock or strut from bottoming out, protect the strut piston and seals, add a progressive rate at full jounce so the car doesn’t smash into the bump harshly, and help keep tyres and suspension geometry happy when the road gets rough. With the front MacPherson setup, the bump-stop slides over the strut shaft and lives under the boot, at the rear, the bump rubber limits movement of the beam/spring so nothing over-travels or fouls.

Because they’re out of sight, they’re easy to forget—until they crumble. Age, Aussie sun and road grime can make the OE foam go chalky and split. If a bump-stop is missing or perished, the car can feel crashy over dips, the strut can bottom out and leak, and mounts or bearings can cop extra stress. It’s worth treating bump-stops as consumables alongside shocks and struts.

• Inspection: check every 20,000–40,000 km, or whenever shocks/struts are out. Look for cracks, missing chunks, or oil-soaked foam. Make sure the dust boot is intact.
• Replacement tips: replace in axle pairs, front or rear. Use OE-style microcellular foam or quality polyurethane foam stops. Many kits include new boots—handy to do together.
• Lowered cars: if the Pulsar’s dropped on springs, consider shorter bump-stops matched to the new travel. Don’t cut the stops unless the spring/kit supplier specifies it.
• Install notes: seat the stop squarely on the strut shaft or perch, avoid nicking it, and torque fasteners to the Nissan service manual specs. After front strut work, get a wheel alignment.

Owners chasing a quieter, more controlled ride—especially on country lanes and pockmarked city streets—will notice the difference when fresh bump-stops go in. They’re cheap insurance for the shocks and a nicer way to take the odd whoop or pothole.

Popular questions about 1999 Nissan Pulsar bump-stops

How can someone tell their Pulsar’s bump-stops need replacing?
Common signs include a sharp, hard thud over big bumps, clunks at full load or with passengers in the back, or visible cracking and crumbling when the dust boot is pulled back. If the shocks are leaking or the car’s been bottoming out, the stops have likely been doing it tough and should be replaced with the dampers.

Do bump-stops affect ride height or alignment?
They don’t set ride height, but they do control what happens at the end of travel. Worn or too-tall stops can make the ride feel harsh sooner in the stroke. Any front strut work—bump-stops included—should be followed by a wheel alignment to keep the Pulsar tracking straight and tyre wear even.

What material is best for replacement bump-stops?
OE-style microcellular foam is ideal for a factory ride and progressive feel. Quality polyurethane foam versions can be more durable, which suits rougher roads or a slightly lowered setup. Match the stop height and rate to the springs and shocks being used.
