Parts for your 2004 Mitsubishi Pajero-Driveshafts

2004 Mitsubishi Pajero driveshafts: what they do and how to look after them

Driveshafts are absolutely relevant and fitted to the 2004 Mitsubishi Pajero (NM/NP series). Technical references including the Mitsubishi Pajero/Montero NM–NP Workshop Manual (2000–2006) and Mitsubishi’s ASA/CAPS parts catalogue show the vehicle uses a rear propeller shaft to the rear differential, a front propeller shaft to the front differential via the transfer case, and front CV half‑shafts to each front wheel as part of its Super Select 4WD system.

On this Pajero, driveshafts transfer torque from the transfer case to the diffs (prop shafts) and from the front diff to the wheels (CV shafts), letting it cruise on the motorway or crawl over ruts without fuss. When they’re healthy, you get smooth take‑offs, quiet touring, and predictable 4WD engagement. When they’re tired, you’ll notice vibrations, clunks, or clicking on turns.

As part of routine servicing on a 2004 Pajero, it’s smart to check the driveline every 10,000–15,000 km or at each service interval:

• Inspect CV boots for splits or grease fling, replace damaged boots promptly to save the joint.
• Check universal joints and the centre bearing on the prop shafts for play, rust dust, or stiffness, grease serviceable joints, replace sealed joints if worn.
• Look for dents in the prop shafts and signs of imbalance or fresh contact marks around the underbody.
• After water crossings or beach work, rinse and re‑inspect boots, slip joints, and flanges.

Replacement tips for workshop or competent DIY: mark flange orientations before removal to maintain balance, support the shafts so they don’t hang on the joints, renew flange bolts/lock nuts where specified and torque to the workshop manual, and if a front CV shaft is changed, fit a new axle nut and stake it correctly. If the slip joint is separable, keep the yokes in phase. After fitting, take a gentle test drive and check for vibration under light throttle at 60–90 km/h, a persistent buzz can indicate joint angle issues or imbalance.

Common signs it’s time for attention include a rhythmic vibration with road speed, a clunk shifting between drive and reverse, or a clicking noise on tight turns (front CVs). Left too long, a failing joint can snowball into diff seal leaks or transfer case wear, so sorting it early is the cheaper, calmer option.

• Does a 2004 Pajero have one or two driveshafts?

It runs a rear propeller shaft to the rear diff and a front propeller shaft to the front diff, plus two front CV half‑shafts to the wheels. So, effectively four driveshaft components in the system.

• How long do Pajero driveshafts last, and what are the warning signs?

With regular checks and greasing (where applicable), prop shafts can last well past 250,000 km. CV shafts often run similar distances if the boots stay intact. Warning signs include vibration with speed, clunks on take‑off, or clicking when turning.

• Is it OK to drive with a torn CV boot?

Not advisable. Once the boot splits, grease escapes and grit gets in, accelerating wear. Catch it early and a boot replacement can save the joint, wait too long and you’ll be up for a full CV shaft.
