Parts for your 1991 Mitsubishi Pajero-Bump stops

1991 Mitsubishi Pajero bump-stops

Based on technical sources including the Mitsubishi Pajero Factory Service Manual for the 1991 model year (Chassis and Suspension sections), the Mitsubishi ASA/CAPS electronic parts catalogue for L040/NH-series Pajero, and general aftermarket catalogues for suspension service items, bump-stops (also called jounce or rebound rubbers) are fitted to the 1991 Mitsubishi Pajero at both the front and rear. They’re there from factory to protect the suspension, shocks, and chassis from metal-to-metal contact at full compression or droop.

On a 1991 Pajero used on Aussie or Kiwi roads and tracks, bump-stops quietly do a big job. When the suspension compresses hard—hitting a pothole, landing off-road, towing a load, or with a fully packed rig—the rubber stops cushion the last bit of travel. That reduces harsh thuds, saves shocks from bottoming out, and prevents control arms or the axle housing from belting the chassis. They also help keep geometry in check at the limits, which can make the vehicle feel more controlled when pushed.

Servicing-wise, they’re simple but worth a look every time the Pajero is on a hoist. Rubber ages, especially with UV, oil, and mud. If a stop is cracked, perished, or missing, it’s cheap insurance to replace it. Many owners stick with OE-style rubber for comfort, while others choose polyurethane for extra durability and a firmer stop—handy on lifted rigs or ones that see a lot of corrugations. If the vehicle’s been lifted or fitted with long-travel shocks, consider extended bump-stops to protect shocks, CVs, and spring seats.

• Check at regular services (or every 10,000–20,000 km): look for splits, chunks missing, or shiny witness marks from hard contact.
• If there’s frequent “bangs” over big hits, or the Pajero bottoms out on modest bumps, the stops may be worn or the suspension may be sagging.
• When replacing: clean the mounting faces, use anti-seize on bolts if appropriate, and torque to spec from the service manual. After off-road trips, hose off mud that can chew out rubber.
• Pair bump-stop checks with shock and bush inspections. If stops are hammered, shocks and bushes often need love too.

Keeping the bump-stops healthy helps the 1991 Pajero feel calmer on rough stuff, protects pricey suspension bits, and keeps the old bus riding sweet for the long haul.

Popular questions

Do I need extended bump-stops on a lifted 1991 Pajero?
On a lift, yes—often. Extended stops can prevent over-compression of coils and shocks, and reduce CV and arm angles at full bump. Matching bump-stop length to actual suspension travel is the tidy way to protect components while keeping as much usable travel as possible.

What are the signs my Pajero’s bump-stops need replacing?
Look for visible cracking, missing chunks, or a stop that’s gone soft and deformed. Repeated loud thuds over big hits, scuffed metal contact points, or rub marks on spring seats are classic hints the stops aren’t doing their job. If the suspension has sagged, you’ll also hit the stops more often.

Rubber or polyurethane—what’s better for a 1991 Pajero?
Rubber feels closer to factory and keeps impacts smoother. Polyurethane is tougher and resists oil and abrasion better, but can feel firmer at full bump. Touring rigs and daily drivers often stick with rubber, heavy off-roaders, tow rigs, or lifted setups may prefer poly or extended options.
