Parts for your 1989 Mitsubishi Pajero-Steering rack

1989 Mitsubishi Pajero steering rack — what’s actually fitted

For the 1989 Mitsubishi Pajero (Gen I), a steering rack isn’t used. Technical references including the Mitsubishi factory workshop manual for Gen I Pajero/Montero (Group 37 – Steering), the Mitsubishi ASA electronic parts catalogue for L040-series vehicles, and general repair guides like the Haynes and Gregory’s manuals all show a recirculating-ball steering gearbox with a pitman arm, idler arm, centre (drag) link and tie-rod ends. There’s no rack-and-pinion assembly listed for this model year.

Why no steering rack? In this era, Mitsubishi built the Pajero as a proper ladder-frame 4x4 aimed at rough tracks and towing. The recirculating-ball steering box handles higher impact loads from off-road tyres and suspension movement better than many period rack-and-pinion setups. It also packages neatly with the pitman–idler–centre link layout across long-travel front suspension, keeps steering effort reasonable (especially with power steering), and offers durability in dusty, muddy conditions where a rack could be more exposed.

So, anything labelled “1989 Pajero steering rack” isn’t the right part. The correct steering service targets are the gearbox (steering box), pitman arm, idler arm and bracket, centre link and tie-rod ends, along with the power-steering pump, hoses and cooler. Free play is adjusted at the steering box as per the factory spec, not by replacing a rack. If there’s a clunk over corrugations or vague on-centre feel, the idler arm bush/pivot and the centre link are usual suspects, if there’s fluid on the chassis rail, check the steering box sector-shaft seal and hose crimps. Boots you’ll see on this Pajero are tie-rod and ball-joint dust boots, not a “rack boot”.

Good servicing practice for this model includes: periodic inspection for play at the idler and tie-rods, checking steering box mounting bolts, setting steering box preload only to spec (over-tightening can cause binding), replacing worn pitman/idler tapers, refreshing power-steering fluid, and finishing with a proper wheel alignment. Converting to rack-and-pinion on this chassis isn’t a straightforward or commonly approved mod in AU/NZ—engineering, clearance, and compliance hurdles make it impractical for most owners.

• Typical symptoms to investigate: steering wander, uneven tyre wear, free play at the wheel, fluid leaks, or a knock over bumps.
• Common fixes: idler arm rebuild/replacement, tie-rod ends, centre link, steering box seal kit or adjustment, power-steering hose replacement.

Popular questions about 1989 Mitsubishi Pajero steering rack

Does a 1989 Pajero have a steering rack?
No. It uses a recirculating-ball steering box with pitman arm, idler arm, centre link and tie-rod ends. This is confirmed by the factory workshop manual and the Mitsubishi ASA parts catalogue for L040-series vehicles.

What should be serviced instead of a steering rack on this model?
Focus on the steering box (adjustment and seals), idler arm assembly, pitman arm, centre link and tie-rod ends, plus the power-steering pump and hoses. Play at the idler and centre link is a common cause of vague steering.

Can a 1989 Pajero be converted to rack-and-pinion?
It’s not a typical or simple conversion. Packaging, geometry, and engineering compliance in AU/NZ make it complex and costly. Most owners restore the factory system with quality parts and correct adjustment for excellent results.
