Parts for your 2004 Mitsubishi Pajero-Bump stops

2004 Mitsubishi Pajero bump-stops: what they do and when to replace them

Yes, the 2004 Mitsubishi Pajero uses bump-stops. Mitsubishi’s own technical literature confirms it: the Pajero NM/NP series (2000–2006) Workshop Manual (chassis sections Group 33A – Front Suspension and Group 34 – Rear Suspension) specifies jounce bumpers/bump-stops on both ends, and the Mitsubishi ASA/CAPS genuine parts catalogue lists them as “stopper, front suspension” and “stopper, rear suspension.” On this model’s independent front and rear suspension, the bump-stops act as the final compression buffer to protect arms, shocks, and chassis when the suspension reaches maximum travel—especially off-road or with a heavy load.

On a 2004 Pajero, bump-stops serve as a secondary spring. They soften the hit at full bump, stop metal-to-metal contact, and help control body movement so the ride stays composed over corrugations, ruts, and potholes. They also protect shock absorbers from bottoming out, which can blow seals and overheat fluid. If the vehicle’s seen beach runs, towing, or plenty of gravel kilometres, the rubber can harden, crack, or get chewed up, reducing their ability to cushion those last few millimetres of travel.

Owners should consider inspection or replacement when they notice:

• A sharp thud at full compression or when dropping off ledges
• Visible cracking, chunks missing, or perishing of the rubber
• Oil-soaked bump-stops (often from a leaking shock) or distorted shape
• Sagging ride height causing frequent contact with the bump-stop
• Uneven tyre wear tied to bottoming or harsh bump behaviour

As part of regular servicing, a quick look at each bump-stop is easy: check the mounting studs/brackets for looseness or rust, and make sure the contact faces are clean. On the Pajero, the stops are simple bolt-on items—front to the lower control arm/frame area and rear near the arm/frame—so swapping them is usually straightforward. Stick with quality OE-style rubber for factory feel, or go with tuned polyurethane/options designed for touring loads or moderate lifts. If the front torsion bars have been cranked or the rear coils upgraded, re-check clearance to ensure the bump-stops engage progressively rather than all at once.

Good practice: inspect every 10,000–15,000 km or before/after big trips, replace in pairs on the same axle, and torque fixings to spec from the Mitsubishi Workshop Manual. Healthy bump-stops help keep the Pajero riding quietly and protect the pricey bits underneath.

• How do you tell if your 2004 Pajero’s bump-stops are worn?
  Look for cracks, missing chunks, or a glossy, hardened surface. A loud clunk at full compression or frequent bottoming on speed humps can also point to tired bump-stops. If the shocks are leaking, the stops may be oil-soaked and softened, which reduces their cushioning.
• Are upgraded bump-stops worth it for touring or towing?
  They can be. Performance or progressive bump-stops can add support at the end of travel and improve control with accessories, campers, or roof loads. Match them to your ride height and spring rates so engagement is smooth rather than harsh.
• Could damaged bump-stops affect a WOF or roadworthy?
  Potentially, yes. Inspectors in NZ and Australia expect suspension components to be secure and serviceable. Missing or badly deteriorated bump-stops can be flagged because they’re part of the suspension’s safety and durability system.
