Parts for your 1997 Mitsubishi Pajero-Wheel bearings

1997 Mitsubishi Pajero wheel bearings: what they do and when to service them

Wheel bearings are absolutely fitted to the 1997 Mitsubishi Pajero and are very much a relevant service item. Factory documentation confirms this: the Mitsubishi Pajero 1991–1999 Factory Service Manual (Front/Rear Axle groups), the Gregory’s Mitsubishi Pajero 1991–1998 manual, the Haynes Pajero/Montero manual, and the Mitsubishi ASA parts catalogue all list front and rear wheel bearings for these models. Up front the Pajero uses opposed taper-roller bearings with adjustable preload inside the hub, at the rear it uses taper-roller bearings on the axle (semi-floating or full-floating depending on variant/trim and market).

On this generation Pajero, wheel bearings let the wheels spin smoothly under load while keeping the hub located precisely. They carry vehicle weight, braking forces, and cornering loads—especially off-road—so good bearings mean quiet running, predictable steering and even tyre wear. When they wear, they can howl or hum, add looseness to steering, and in the worst case allow wobble that can damage hubs, discs, or axle seals.

For servicing, the front bearings are designed to be cleaned, inspected, and repacked with high-temperature wheel bearing grease. A typical off-road or towing schedule is to check them every 30,000–40,000 km, or sooner after deep water crossings, beach work, or heavy corrugations. Replacement is straightforward for a competent home mechanic: remove the freewheel hub/drive flange, brake caliper and rotor, pull the hub, then clean, inspect races, fit new grease seals, pack fresh grease into quality bearings (Koyo/NTN/Timken are common OE-grade choices), set preload per the service manual, and secure the lock washer/nut. Always use new grease seals and a new cotter/split pin where applicable.

Rear bearings vary by axle type. Some are pressed onto the axle shaft with a retaining collar, removal typically needs a press and specific pullers. It’s wise to renew the axle oil seal at the same time to prevent diff oil leaks onto brakes. If the vehicle has ABS, take care around sensors and tone rings during disassembly.

• Common warning signs: a growing humming/rumble with speed, heat at the hub, grease leakage past the inner seal, or play when rocking the wheel at 12 and 6 o’clock.
• Handy tips: keep everything spotless, don’t overpack grease, and follow the Pajero manual’s torque/preload sequence rather than guessing “by feel”.

FAQs

What are the signs a 1997 Pajero wheel bearing is failing?
Drivers usually notice a low growl that rises with road speed, sometimes changing tone on gentle lane changes. There may be play at the wheel when lifted, heat at the hub after a drive, or ABS warning if a very loose bearing upsets sensor gaps. Address it early to avoid hub or axle damage.

How often should front wheel bearings be repacked?
For mixed on-road use, inspect/repack around every 30,000–40,000 km. If the Pajero regularly tackles mud, water, beaches, or heavy towing, shorten intervals—checking after any deep water crossing is smart. Fresh grease and clean seals go a long way to long bearing life.

Can a home mechanic replace Pajero wheel bearings?
Front bearings are DIY-able with basic tools, a torque wrench, a seal driver, and quality grease. Rear bearings on some axles need a press and specific pullers, many owners farm that job out to a workshop. Either way, follow the factory procedure for preload and locking hardware.
