Parts for your 1988 Mitsubishi Pajero-Ball joints

1988 Mitsubishi Pajero ball joints — what they do and when to sort them

Ball joints are absolutely relevant on a 1988 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero/Montero Factory Service Manual (1983–1991, Group 33A Front Suspension), Gregory’s Service and Repair Manual for Pajero 1983–1991 (AU), and the Mitsubishi ASA parts catalogue (listing upper ball joint MB241239/MB241240 and lower MB176742/MB176743 for 1988 models) confirm the front suspension is a torsion-bar, double-wishbone design with upper and lower ball joints.

On this first‑gen Pajero, the ball joints connect the steering knuckle to the upper and lower control arms. They let the front wheels steer left and right while the suspension moves up and down, keeping alignment stable and steering feel tidy. Given the Pajero’s off‑road chops and frequent corrugations, these joints cop plenty of load, so keeping them in good nick is key for safe touring and even tyre wear.

There’s no fixed replacement interval, they’re serviced on condition. At regular services (say every 10,000–20,000 km), it’s smart to check the dust boots for splits, look for grease seepage, and test for play with the wheel safely off the ground. Many OE joints are sealed, some aftermarket versions add grease nipples. If they’re greasable, a quality NLGI 2 lithium complex chassis grease does the trick—don’t overfill and always wipe away excess.

• Common signs they’re tired: clunks over bumps, wandering or vague steering, uneven tyre wear, clicking when turning, or play when rocking the wheel at 12 and 6 o’clock.
• If any measurable looseness is found or the boot’s torn, replacement is the go.

Replacement on the ’88 Pajero is straightforward for a competent home mechanic. The upper and lower joints are bolt‑on types to the control arms, with the stud tapering into the knuckle. Support the lower arm with a jack, crack the taper with a separator (not a hammer on the knuckle), and replace cotter pins on reassembly. Torque everything to factory spec from the service manual. It’s wise to replace in axle pairs (both uppers or both lowers) and book a wheel alignment straight after—new joints change camber and caster, so an alignment keeps tyres wearing evenly and the steering tracking straight.

Look after the ball joints and the old Pajero stays tight, safe, and ready for the next run up the beach or down a gravel back road.

Popular questions about 1988 Mitsubishi Pajero ball joints

How do I tell if my 1988 Pajero’s ball joints are worn?

Listen for clunks over bumps, feel for vague or wandering steering, and check for uneven tyre wear. With the front wheel off the ground, rock it at 12 and 6 o’clock, any noticeable free play or clicking often points to a tired joint. A split dust boot is another giveaway—once grit gets in, wear accelerates quickly.

Are the Pajero’s ball joints greasable or sealed?

Factory joints on many 1988 models are sealed. However, plenty of aftermarket replacements include grease nipples. If yours have nipples, give them a light pump of quality NLGI 2 chassis grease at service time. If they’re sealed, don’t try to add grease—inspect the boots and replace the joint if the boot’s damaged or there’s play.

Do I need a wheel alignment after replacing ball joints?

Yes. Changing ball joints can alter camber and caster on the double‑wishbone front end. A proper alignment right after replacement keeps steering feel crisp and prevents premature tyre wear, saving money and hassle down the track.
