Parts for your 1989 Mitsubishi Pajero-Steering bushes

1989 Mitsubishi Pajero steering bushes

Technical references for the first‑generation Pajero (1982–1991) – including the Mitsubishi Workshop Manual, Group 37: Steering, and the Haynes Pajero/Montero manual (’83–’96) – confirm the 1989 Pajero runs a recirculating‑ball steering box with a pitman arm, idler arm and centre link. The system uses steering bushes in the idler arm assembly and within the steering column support. There’s no rack, so no “rack bushes”, but steering bushes are definitely fitted and relevant on this model.

On a 1989 Pajero, steering bushes keep the linkages aligned, soak up vibration and maintain consistent geometry from the steering box through to the drag link and tie rods. The idler arm bushes, in particular, control side‑to‑side movement of the centre link under load. When these bushes are healthy, the wheel feels planted and predictable, with less kickback over corrugations and ruts – exactly what’s wanted on Aussie and Kiwi roads and tracks.

Because many Gen‑1s see off‑road work, the bushes can wear faster from dust, mud and repeated articulation. It’s smart to inspect them at regular servicing intervals (every 20,000 km is a good rule of thumb, sooner if it’s doing beach runs or outback touring). Look for cracking or ovaling in rubber bushes, play in the idler arm, and any slop through the steering column lower bush.

• Common symptoms: vague on‑centre feel, steering wheel shimmy, clunks over potholes, wander at highway speeds, or uneven tyre wear.
• Quick checks: with the front end safely supported, rock a wheel at 3 and 9 o’clock, watch the idler arm for lift or lateral play.
• Parts choice: OEM‑style rubber keeps NVH low, quality polyurethane sharpens response but can transmit more road feel.
• Fitment tips: torque fasteners at normal ride height to avoid preloading, recheck after a short drive.
• Aftercare: always get a wheel alignment and re‑centre the steering wheel after bush or idler work.

Replacement is straightforward with basic tools, though a press or suitable drivers help with idler bushes. Follow manual torque specs, ensure the idler arm pivot is square to the chassis bracket, and inspect the steering box mount bolts while there. A dab of appropriate assembly grease on polyurethane sleeves can prevent squeaks. Once sorted, the old bus will track straighter, steer lighter and be far less fussy on corrugations.

Popular questions

Do 1989 Pajeros have steering rack bushes?
No. This model uses a recirculating‑ball steering box rather than a rack‑and‑pinion. The relevant “steering bushes” are in the idler arm assembly and the steering column support. If someone’s asking for rack bushes on a Gen‑1 Pajero, they’re likely chasing idler arm bush kits instead.

How can someone tell their Pajero’s steering bushes are worn?
Typical signs include free play at the wheel, a shimmy over bumps, clunks when turning slowly, or the vehicle wandering and following ruts. A driveway test helps: with the front lifted, rock a tyre at 3 and 9 o’clock while watching the idler arm – any visible lift or side movement points to tired bushes.

Rubber or polyurethane bushes for a Gen‑1 Pajero?
Rubber keeps things quiet and comfy, closest to factory feel. Polyurethane can sharpen steering response and last longer in harsh conditions, but may pass a bit more vibration and can squeak if not greased properly. For touring and daily use, rubber is a safe bet, for lifted rigs and heavier off‑road work, quality poly can make sense.
