Parts for your 1990 Mitsubishi Pajero-Suspension bushes

1990 Mitsubishi Pajero Suspension Bushes

Based on the Mitsubishi Pajero/Montero factory workshop manual for the L040 platform (covering late‑80s to 1991 models), the Mitsubishi ASA electronic parts catalogue, and general repair references such as the Haynes manual for 1983–1996 Pajero, the 1990 Mitsubishi Pajero is absolutely fitted with suspension bushes. These sources detail rubber bushes at the front upper and lower control arms, sway bar mounts and links, shock absorber eyes, and—depending on trim—either rear leaf spring eye/shackle bushes or trailing arm and Panhard rod bushes on coil‑spring variants.

On a 1990 Pajero, suspension bushes are the quiet achievers. They isolate vibration, keep alignment stable, and let the arms and links pivot smoothly without metal‑on‑metal contact. With the Pajero’s independent front suspension (double wishbones with torsion bars) and live‑axle rear (leaf springs on many Aussie/NZ models of the era, coils on some trims), healthy bushes mean tighter steering feel, surer braking, and less tyre scrub on and off the blacktop.

Age, UV, mud, oil contamination, and corrugations will harden, crack, or oval out the bushes. As part of regular servicing, it’s smart to check them every 10,000–15,000 km or annually, and more often if the vehicle sees beach work or rough tracks. Look for perishing, splits, displaced sleeves, and shiny witness marks from movement. Pry bars and a keen eye will reveal excessive play, any clunks on take‑off, vague steering, or cupped tyre wear are common tells.

When replacing, do the lot in logical sets—front lower arm bushes together, sway bar D‑bushes and links as a pair, and both ends of a leaf spring. Press‑in bushes need proper support to avoid bending arms. Always torque suspension bolts at normal ride height so the rubber sits neutral, tightening at full droop will preload the bush and shorten its life. Genuine‑style rubber keeps NVH civil for touring, while quality polyurethane can sharpen response for towing or heavy off‑road use—just expect a touch more road feel. After bush work, get a wheel alignment, and re‑check fasteners after a few hundred kays.

• Tell‑tales: clunks over bumps, wandering on the highway, uneven tyre wear, or knocking under braking.
• Service tip: clean and inspect sway bar D‑bushes and link bushes—cheap parts, big improvement.
• Off‑road note: oil leaks can swell rubber, fix the leak and replace contaminated bushes promptly.

What are the signs the Pajero’s suspension bushes are worn?

Owners usually notice clunks over potholes, steering that won’t self‑centre properly, or wandering at 90–110 km/h. Uneven or rapid tyre wear and a thunk when shifting from drive to reverse can also point to tired control arm or trailing arm bushes.

A quick visual check for cracks, tearing, or displaced sleeves, plus levering the arms to feel for play, will confirm it. Any movement between the sleeve and the arm is a red flag.

How often should bushes be replaced on a 1990 Pajero?

There’s no hard interval—condition and use matter. Many original rubber bushes last 150,000–250,000 km on road, but sand, mud, corrugations, and oil exposure can halve that. Inspect annually, and plan replacement when cracks appear or geometry can’t be held during alignment.

Do them in pairs/sets and book an alignment afterwards to protect your tyres.

Rubber or polyurethane—what suits Aussie/Kiwi conditions?

Rubber keeps NVH low and suits daily driving and touring. Polyurethane firms things up, resists oil, and holds alignment better under load—handy for towing and rutted tracks—but can pass a bit more vibration and needs correct lubrication where specified.

Match the material to how the Pajero is used, and stick with reputable brands for bush hardness and fitment accuracy.
