Parts for your 1990 Mitsubishi Pajero-Driveshafts

1990 Mitsubishi Pajero driveshafts

Driveshafts are absolutely relevant and fitted to the 1990 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero/Montero Factory Service Manual (1989–1991 editions), the Haynes Montero/Pajero Workshop Manual (1983–1996 coverage), and the Mitsubishi ASA parts catalogue specify front and rear propeller shafts from the transfer case to the differentials, plus front CV driveshafts to each wheel on IFS models. Many long‑wheelbase variants also use a two‑piece rear shaft with a centre bearing.

On this classic 4WD, the driveshafts transfer engine torque through the gearbox and transfer case to the front and rear diffs, and then via CV shafts to the front wheels. Universal joints (U‑joints) and slip yokes allow length change and angular movement as the suspension works, while CV joints maintain smooth drive on steering lock. Properly functioning shafts keep the Pajero quiet, smooth and reliable on-road and out bush.

For routine servicing, it pays to inspect the shafts every service and especially after water crossings or corrugations. Greasable U‑joints and slip joints should be lubricated at 10,000–15,000 km intervals (more often for heavy off‑road use). Check the front CV boots for splits and fling, and look over the flange bolts for tightness and witness marks. A quick visual for dents, missing balance weights and tired centre bearings on two‑piece rears helps prevent bigger dramas later.

• Clunks on take‑up or gear changes can point to worn U‑joints or a sloppy slip yoke.
• Vibration under load at certain speeds (often 60–90 km/h) suggests imbalance, joint wear or poor phasing.
• Clicking on full lock during slow turns indicates a tired front CV joint or split boot.
• Shudder on launch can be a failing centre bearing or incorrect driveshaft angle.
• Grease sling around a boot or uni usually means contamination and impending failure.

When replacing, match shaft length and spline counts to VIN, mark flanges before removal to maintain balance, keep yokes in phase, and torque fasteners to the workshop manual spec with new hardware where specified. After refit, road‑test and recheck for leaks at transfer and diff seals, then re‑torque after a short run. A properly balanced, well‑greased set of shafts keeps the 1990 Pajero feeling tight and ready for the next mission.

How often should the 1990 Mitsubishi Pajero driveshafts be serviced?

They benefit from an inspection at every regular service. Grease any serviceable U‑joints and slip joints every 10,000–15,000 kilometres, or sooner if the vehicle has been in mud, sand or water. Check front CV boots at the same time, a small split can quickly turn into a noisy CV joint.

What are common signs a Pajero driveshaft or CV is failing?

Tell‑tales include clunks on take‑up, vibration at highway speeds, shudder off the line, and grease flung around a joint. Clicking while turning on full lock points to a worn front CV. A droning or rumbling that changes with throttle may indicate a tired centre bearing on two‑piece rear shafts.

Are the LWB and SWB 1990 Pajero driveshafts the same?

No. Long‑wheelbase models commonly use a two‑piece rear propeller shaft with a centre bearing, while many short‑wheelbase versions use a single‑piece rear shaft. Lengths, yokes and spline counts vary, so parts should be selected by VIN or exact model code to ensure correct fit and balance.
