Parts for your 2004 Mitsubishi Pajero-Wheel bearings

2004 Mitsubishi Pajero wheel-bearings

Wheel-bearings are absolutely relevant and fitted to the 2004 Mitsubishi Pajero (NM/NP series). Technical references including the Mitsubishi Pajero/Montero NM–NP Workshop Manual (Suspension and Front/Rear Axle sections) and Mitsubishi ASA parts catalogue specify sealed, double-row hub bearings at the front and rear. Major OEM bearing catalogues (NTN/KOYO) also list front and rear wheel bearings for the 2004 Pajero. That confirms this model uses serviceable hub bearings rather than a bearing-less arrangement.

The 2004 Pajero relies on sealed hub-style wheel bearings to let each wheel spin smoothly with minimal friction while supporting vehicle weight and coping with cornering and braking loads. On- and off-road, they help keep the Pajero quiet, sure-footed and kind to its tyres. Because they’re sealed, there’s no regular greasing like the old-school tapered setups, instead, they’re designed to run for years, then be replaced once they wear.

As part of routine servicing, it’s smart to have a listen and a feel every 10,000–15,000 km. A low hum that grows with speed, a droning that changes when weaving the steering, or play felt at the wheel when the vehicle’s jacked up are classic signs the bearing is on the way out. ABS warning lights can also pop up if a worn bearing upsets the tone ring or wheel-speed signal.

When replacement time comes, the Pajero’s bearings are a press-fit into the hub/knuckle assembly. It’s a job that calls for the right pullers and a press, plus care not to load the new bearing through the wrong race. Many owners hand it to a workshop, especially where ABS sensors and circlips are involved. Always torque the axle nut and fasteners to the factory spec from the workshop manual and consider a wheel alignment check afterwards.

Quality matters here: go for reputable brands that meet OEM spec to handle the Pajero’s weight and towing/off-road use. While it’s not mandatory, replacing bearings in pairs (both fronts or both rears) can help keep noise and performance consistent. With good parts and proper installation, a set of Pajero wheel-bearings will typically run well past 150,000 km, even with a bit of Kiwi or Aussie corrugation thrown in.

• Common symptoms: humming/growling noise, steering vibration, ABS light, uneven tyre wear
• Service tip: check for play and roughness at each major service, especially after water crossings

Popular questions about 2004 Mitsubishi Pajero wheel-bearings

How long do Pajero wheel-bearings usually last?
On a well-maintained 2004 Pajero, sealed bearings commonly last 150,000–250,000 km. Heavy loads, mud, water crossings and bigger tyres can shorten that. Regular checks during servicing help catch wear early.

Can a home mechanic replace them?
Yes, but it’s not a basic driveway job. The Pajero’s bearings are press-fit and often require a hub puller, a hydraulic press and care around ABS sensors. Many DIYers remove the knuckle and have a machine shop press the old bearing out and the new one in.

Is it safe to drive with a noisy bearing?
Only if absolutely necessary and for a short distance. A failing bearing can overheat, damage the hub, affect braking and steering, and in a worst case seize. It’s best to book it in promptly to avoid bigger bills.
