Parts for your 1998 Mitsubishi Pajero-Universal joints

1998 Mitsubishi Pajero universal joints (U-joints)

Universal joints are absolutely relevant on the 1998 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero/Montero Workshop Manual (Group 22A: Propeller Shaft) and the Haynes Mitsubishi Pajero/Montero Repair Manual confirm that this model uses cross-type universal joints on the front and rear propeller shafts. The Mitsubishi ASA electronic parts catalogue for late-90s Pajero variants also lists universal joint components for the propshaft assemblies. While the front axle half-shafts use CV joints, the propshafts themselves rely on U-joints.

On a ’98 Pajero, the U-joints let the propshaft transmit engine torque to the diffs while the suspension moves and the driveline angles change. That flexibility is vital off-road and on corrugated Kiwi and Aussie roads. When U-joints are healthy and correctly phased, the driveline runs smooth and quiet, when they’re worn, you’ll feel it as vibration, hear it as a chirp or clunk, and may notice a shudder under load or on overrun.

Servicing is straightforward. Many factory Pajero U-joints are sealed-for-life, but some trims and plenty of aftermarket replacements have grease nipples. If yours are greaseable, give them a pump of quality NLGI 2 lithium complex (or lithium-moly) grease every 10,000 kilometres, and after water crossings or beach work. At each service, raise the vehicle safely, chock the wheels, and check for play by gripping the propshaft near each joint, any noticeable movement, rust-coloured dust at the caps, or stiff spots means it’s time to plan a replacement.

Replacement is well within a competent home mechanic’s wheelhouse, but it rewards care. Mark the flanges and yoke positions so the shaft goes back in the same orientation and phasing. Undo the flange bolts, drop the shaft, then press or vice out the bearing caps. Keep the needle rollers in place, seat the new caps squarely, and fit the circlips. If the joint feels notchy after install, a needle’s likely tipped—start again rather than forcing it. Refit using the workshop manual torque settings, and rotate the shaft so any balance marks line up. It’s smart to replace both U-joints on the same shaft at the same time, stick with reputable brands, and recheck for leaks or vibration after a short test drive. That way, the Paj keeps its smooth, torquey feel on highway runs and rutted tracks alike.

• Common symptoms: clunk on take-up, high-speed vibration, chirp that changes with speed, visible rust dust around caps.
• Good habits: grease when possible, inspect after mud/salt, and keep driveline angles within spec if lifting the suspension.

How long do Pajero U-joints usually last?

With mostly road use and no deep water or sand, many last well over 150,000 km. Regular greasing (if fittings are present) and avoiding harsh driveline angles after a lift can stretch that further. Frequent off-road work, water crossings, and beach runs shorten their life.

Can worn U-joints damage other parts?

Yes. A flogged-out U-joint can hammer the pinion bearings, chew out the flange bolts, and cause transmission tailshaft seal leaks. If a joint lets go at speed, it can damage the floor and exhaust. If you feel a new vibration or clunk, don’t leave it.

Do I need a wheel alignment after U-joint replacement?

No. Replacing propshaft U-joints doesn’t affect wheel alignment. Just ensure the shaft is reinstalled in its original orientation and the yokes are correctly phased. If a lift kit is fitted, consider checking driveline angles separately.
