Parts for your 1987 Mitsubishi Pajero-Universal joints

1987 Mitsubishi Pajero universal joints: what they do and how to keep them happy

Universal joints are absolutely used on the 1987 Mitsubishi Pajero. Technical sources that confirm this include the Mitsubishi Pajero/Montero factory service manual for 1983–1991 (propeller shaft section), the Haynes Repair Manual covering 1983–1997 models, and Mitsubishi’s ASA electronic parts catalogue listings for front and rear propeller shafts. All specify cross-type universal joints at each end of the prop shafts linking the transfer case to the differentials.

On a ’87 Pajero, those U-joints let the prop shafts deliver torque while the suspension works and the angles change, whether it’s a short blast to the shops or a rutted fire trail in low range. When they wear, drivers often notice a vibration under load, a clunk when shifting between drive and reverse, a chirping squeak that speeds up with road speed, or rusty dust around the bearing caps.

Plenty of these trucks still run greaseable joints with nipples. If that’s the case, they deserve a hit of quality NLGI #2 lithium-based EP grease every service (around 10,000 km), and after beach work, water crossings, or mud. Keep pumping until clean grease purges from all four caps. If the joints are sealed, inspect them more often and replace at the first sign of play or noise.

• Service tips:
  • Chock wheels and mark the flanges and yokes before removal to keep phasing and balance.
  • Check both front and rear shafts, on long-wheelbase models also inspect the centre support bearing.
  • If one joint has failed, it’s smart to replace the pair on that shaft.
  • Use new circlips and ensure the caps seat fully, any binding means a cap isn’t home or a needle’s tipped.
  • Tighten flange bolts to the workshop manual spec and recheck after the first drive.

Left too long, a flogged-out U-joint can let go and chew up the shaft, transfer case flange, or even the floor. The part itself is inexpensive compared with the drama it can cause, so regular checks, a quick grease, and timely replacement keep a classic Paj tidy, quiet, and ready for the next mission.

Popular questions

How often should Pajero U-joints be greased?
For greaseable joints, every 10,000 km or at each general service works well, and immediately after water crossings, beach work, or mud. Purge until fresh grease appears from all four caps to push out moisture and grit.

Is it safe to drive with a noisy or clunky U-joint?
Not really. Noise and play mean the needles or caps are on the way out. Keep driving and it can fail suddenly, damaging the prop shaft or flanges. Park it up and sort the joint before the next trip.

Can greasing a squeaky U-joint fix it for good?
Grease might quiet a joint that’s just dry, but if there’s rust dust, looseness, or a persistent clunk, the cross is worn. Grease won’t rebuild pitted needles—replacement is the proper fix.
