Parts for your 1993 Mitsubishi Pajero-Universal joints

1993 Mitsubishi Pajero universal joints — what they do and how to look after them

Universal joints absolutely are used on a 1993 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero NH–NJ Workshop Manual (Propeller Shaft section), the Mitsubishi ASA parts catalogue (Group 22: Propeller Shaft/Universal Joint), and common aftermarket application guides from driveline specialists confirm factory-fitted universal joints on both front and rear propeller shafts. The front axle shafts use CV joints, but the prop shafts that run between the transfer case and the diffs use traditional cardan (U-) joints—so they’re very much relevant to any 1993 Pajero.

On a Pajero, the universal joints let the propeller shafts transmit torque while working through changes in angle as the suspension moves and the drivetrain flexes. That keeps the 4WD system smooth on-road and dependable off-road. When U-joints wear, they can cause vibrations, clunks on take-off, and even damage to the shaft or diff flanges if ignored.

For servicing, the workshop guidance for this era recommends periodic lubrication of the propeller shaft U-joints and slip yoke—typically every 10,000 kilometres or six months, and more often after water crossings, beach driving, or dusty tracks. Use a good quality NLGI No. 2 lithium-base multipurpose or EP chassis grease. If the joints are sealed and non-greasable, they’re replaced, not serviced—so inspect them routinely and act early if there’s play or roughness.

Replacement isn’t hard for an experienced home mechanic, but care matters. Mark the flanges so the shaft goes back in the same orientation, keep the bearing caps clean and supported, and press new joints in square. Make sure the circlips seat fully, the yokes are correctly phased, and the slip joint splines are sound and lubricated. After reassembly, tighten fasteners to the factory spec in the workshop manual and road-test for vibration.

• Common signs a Pajero U-joint needs attention:
  • Clunk when selecting drive or on take-off
  • Vibration at highway speeds that changes with throttle
  • Squeak that increases with road speed
  • Rust-coloured dust around bearing caps or noticeable free play

Keeping the U-joints greased and checking for play during routine servicing goes a long way to preserving the Pajero’s trademark reliability—on the blacktop and out in the scrub.

Popular questions about 1993 Mitsubishi Pajero universal joints

How often should the U-joints be greased on a 1993 Pajero?
For greasable joints, a 10,000 km or six‑month interval is a good baseline, with shorter intervals if the vehicle does river crossings, beach work, or corrugations. After any deep water or mud, grease them as soon as practical to purge moisture.

If yours has sealed, non-greasable joints, regular inspection is key—spin and feel for notchiness with the shaft out, and replace at the first sign of wear.

What’s the best grease for Pajero U-joints?
A quality NLGI No. 2 lithium-base multipurpose or EP chassis grease suits the needle bearings in universal joints. For the slip yoke splines, a moly-fortified grease is commonly used. Avoid mixing incompatible greases, if changing types, clean out the old grease where possible.

Can worn U-joints damage other parts?
Yes. Left too long, a flogged U-joint can hammer the flange bolts, wear the yokes, and cause vibrations that stress the transfer case bearings and diff pinion bearings. Replacing a suspect joint early is far cheaper than chasing driveline vibrations later.
