Parts for your 1989 Mitsubishi Pajero-Wheel bearings

1989 Mitsubishi Pajero wheel-bearings: what they do and when to service them

Based on Mitsubishi’s factory service information for the first‑generation Pajero (L040) and well‑known aftermarket manuals such as Haynes, the 1989 Mitsubishi Pajero is fitted with serviceable tapered roller wheel bearings at the front hubs and pressed‑on roller bearings at the rear axle. So wheel-bearings are absolutely relevant to this model. They carry vehicle weight, let the wheels spin freely, and are a routine maintenance item on a 4x4 that sees corrugations, beach sand, and creek crossings.

What do they do? Each hub runs a matched pair of tapered roller bearings that keep the hub centred and control end‑float under cornering and braking. Grease inside the hub lubricates the rollers and protects them from corrosion. On the front of a 4WD Pajero with free‑wheeling hubs, bearing preload is set by a two‑nut and lock‑washer arrangement, at the rear, the bearing is pressed to the axle shaft with a retainer and oil seal.

Servicing is straightforward with the right tools. Front bearings should be cleaned, inspected, and repacked with a quality NLGI 2 high‑temp wheel bearing grease about every 40,000–50,000 kilometres, or sooner after deep water. Replace hub oil seals whenever the hub is apart. Adjust preload to the workshop spec using the inner nut while rotating the hub to seat the rollers, then fit the lock washer and outer nut. A dial indicator is handy to confirm end‑float. Rear bearings generally last longer but, when noisy or loose, need the axle removed and a press to replace the bearing and retainer, many owners hand that job to a workshop.

• Watch for a humming or rumbling that rises with road speed, changing when weaving gently.
• Feel for play when rocking the tyre at 12‑and‑6 o’clock, any clunk points to adjustment or wear.
• Check for heat at the hub after a drive, grease leakage, or a torn seal.
• Uneven tyre wear or vague steering can also hint at worn front bearings.

Use reputable bearings and seals, clean everything thoroughly, and torque fasteners to the manual’s figures. After any bearing work, recheck preload after a short shakedown as the grease settles. Looked after, Pajero wheel bearings will shrug off Kiwi backroads and Aussie tracks for years.

FAQs

How often should wheel bearings be serviced on a 1989 Pajero?
Front bearings appreciate a clean, inspect, and repack roughly every 40,000–50,000 km, or straight after serious water crossings. The rears aren’t typically repacked, they’re replaced when noisy, rough, or loose, with new seals and retainer.

What are the signs of worn wheel bearings on this model?
A steady humming or growl that changes when you gently swerve, warmth at the hub after a drive, visible grease leaks, or noticeable play when you rock the wheel at 12‑and‑6 are classic clues. Steering that feels vague can also come from sloppy front bearing preload.

Can a competent DIYer replace Pajero wheel bearings?
The fronts, yes—provided they have a hub nut socket, torque wrench, quality grease, and new seals, and they follow the preload procedure. The rears need axle removal and a press to swap the bearing and retainer, so many DIYers prefer a trusted workshop for that end.
