Parts for your 1986 Mitsubishi Pajero-Wheel bearings

1986 Mitsubishi Pajero wheel bearings

Wheel bearings are absolutely fitted to the 1986 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero/Montero factory service manual (1983–1991), the Haynes Mitsubishi Pajero/Montero manual (1983–1996), and the Mitsubishi ASA parts catalogue list front hub tapered roller bearings and rear axle bearings for this model. So wheel bearings are relevant to servicing and reliability on any 1986 Pajero, whether short- or long-wheelbase.

On this classic 4WD, wheel bearings let the wheels and hubs spin smoothly while carrying the Pajero’s weight and the loads from braking, cornering, corrugations, and four-wheel driving. The front end uses serviceable tapered roller bearings, which are designed to be cleaned, inspected, re-greased, and adjusted. The rear axle uses pressed-on bearings on the axle shafts that run for high mileages when properly sealed and lubricated.

For front bearings, regular attention pays off. During a service, the hubs are removed, bearings and races cleaned and inspected for pitting or discolouration, then packed with a quality high-temperature NLGI 2 wheel bearing grease. New hub seals are fitted, and the bearings are adjusted to the specified end float/preload while rotating the hub, then locked. Over-tightening overheats and ruins tapered rollers, too loose and the hub develops play, which chews out tyres and brake components. As a rule of thumb, Pajero owners who tow, hit the beach, or see regular river crossings should have the fronts checked and re-greased more often—around every 20,000–40,000 kilometres or annually, whichever comes first.

The rear bearings are a different story. They typically show their age with a low rumble that rises with road speed, or by diff oil weeping at the backing plate due to a tired axle seal. Rear bearing replacement needs a press, new retainer and seal, and the right set-up—best left to a workshop that knows old Mitsis. Any sign of metal flake in the oil or looseness at the wheel means it’s time.

Common signs a Pajero’s wheel bearings need attention include:

• A humming or growl that changes with speed or when weaving slightly
• Noticable play at the wheel when rocked at 12 and 6 o’clock
• Uneven tyre wear, heat at the hub, or grease/oil leakage at the seal

Quality bearings and seals (preferably reputable Japanese brands), careful cleanliness, correct adjustment, and proper torque on the hub fasteners will keep a 1986 Pajero tracking straight and quiet for years.

FAQs

How often should the front wheel bearings be re-greased on a 1986 Pajero?
For typical mixed on-road use, plan on every 20,000–40,000 kilometres or annually. If the vehicle regularly sees mud, sand, water crossings, or heavy towing, shorten the interval and check them after any deep-water work.

What grease is best for Pajero front wheel bearings?
Use a high-temperature, high-load NLGI 2 wheel bearing grease (commonly lithium complex, some prefer a moly-fortified wheel bearing grease). Avoid mixing different grease types—clean out the old grease if changing product.

Is it safe to drive with a noisy wheel bearing?
Not for long. A noisy bearing can overheat and seize, risking hub damage or loss of a wheel. If a hum or growl appears, reduce driving and book a repair promptly.
