1987 Mitsubishi Pajero Ball Joints — What they do and when to replace

Ball joints are absolutely relevant on the 1987 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero (L040 series) Factory Service Manual for 1982–1991 models, the Mitsubishi ASA electronic parts catalogue, and mainstream workshop guides (e.g., Haynes and Gregory’s) specify a double wishbone, torsion-bar independent front suspension with both upper and lower ball joints. The rear is a live axle without ball joints, but the front end definitely relies on them for steering and suspension articulation.

On this first‑gen Pajero, ball joints act like the hip joint of the front suspension: they let the steering knuckle pivot while the control arms move up and down. That controlled movement keeps tyre contact stable over rough tracks and bitumen alike, which is why worn joints show up as vague steering, clunks over corrugations and uneven tyre wear. With the Pajero’s off‑road pedigree, those joints cop a fair hiding compared with soft-roaders, so regular checks are just sensible maintenance.

From a servicing point of view, inspect the rubber dust boots for splits, weeping grease or mud ingress at every service or after big water crossings. Any play you can feel with the wheel jacked up (hands at 12 and 6 o’clock) is a red flag. Many original joints are sealed-for-life, while some aftermarket replacements include grease nipples, if yours are greasable, a light pump of quality chassis grease at service intervals helps longevity.

Replacement is straightforward for a competent home mechanic with a jack, stands and the right puller, but it’s still a safety-critical job. Follow workshop-manual procedures, note taper orientation and cotter pin fitment, and torque to spec. It’s smart to replace upper and lower on the affected side together, and many owners do both sides to keep wear even. After any ball joint work, a professional wheel alignment is a must to protect tyres and restore on-road manners.

• Tell-tales of wear: clunking on bumps, wandering or tramlining, steering shimmy, uneven or rapid tyre wear, and visible boot damage.
• Quick tips: keep boots intact, avoid pressure-washing directly at seals, grease only if designed for it, and check more often if you tow or hit heavy tracks.

Popular questions about 1987 Mitsubishi Pajero ball joints

How long do ball joints last on a 1987 Pajero?
Service life varies with use. A lightly driven road-going Pajero might see well over 100,000 km from quality joints. Regular off-roading, bigger tyres or lift kits can shorten that significantly. Frequent inspections and keeping boots intact make the biggest difference.

Do I need an alignment after replacing ball joints?
Yes. Any change to the control arm or knuckle interface can shift camber and caster. A proper alignment after replacement protects tyres, improves steering feel and ensures the Pajero tracks straight.

Can I drive with a worn ball joint?
It’s risky. Minor wear quickly becomes play, which can damage tyres and other front-end components. If a ball joint fails, you can lose control. If there’s noticeable play or noise, park it until it’s fixed.
