Parts for your 1998 Nissan Navara-Steering bushes

1998 Nissan Navara steering-bushes — relevance, purpose and service advice

Steering-bushes are relevant to the 1998 Nissan Navara (D22). According to the Nissan D22 Factory Service Manual (Steering System – ST section) and common aftermarket catalogues for the D22 platform, this model uses a recirculating-ball steering box with a pitman arm and an idler arm. The idler arm pivots on bushes, and those bushes are serviceable wear items. There’s no steering rack on this model, so “rack-mount bushes” don’t apply, but idler arm bushes (and, less commonly, a steering column support bush) are part of the steering system.

On a 1998 Navara, the steering-bushes in the idler arm keep the centre link running true and stop slop from developing as the wheels are turned. When they’re in good nick, the ute tracks straight, the wheel centres up nicely after corners, and there’s a solid, predictable feel through the wheel. As they wear, the steering can go vague, the front end may shimmy over corrugations, and it’s not unusual to hear a knock through the column on rough roads.

As part of regular servicing, it’s smart for owners to ask for a steering-bushes inspection every 10,000–15,000 km, or sooner if the Navara does lots of outback kilometres or towing. A quick check involves safely lifting the front, supporting on stands, and having someone rock the steering while another watches the idler arm. Any sideways movement at the idler pivot usually points to tired bushes. A gentle pry-bar test on the idler also shows excess play.

Replacement is straight-forward for a workshop: the idler arm comes off, the old bushes are pressed out, and new bushes go in with the correct lube (if polyurethane) and orientation. It’s worth inspecting the idler shaft and arm for ovaling, if they’re flogged out, a complete idler arm assembly may be the better fix. After refit, the fasteners should be torqued to the D22 spec and a wheel alignment carried out, because any play previously present will have affected toe.

Choosing material comes down to how the Navara is used. OE-style rubber bushes are quiet and comfy, great for daily driving. Quality polyurethane bushes can sharpen steering feel and often last longer off-road, but may transmit a touch more road texture, look for greaseable designs and use the correct grease to avoid squeaks. Either way, fresh steering-bushes restore confidence and make the old D22 feel tight again.

• Typical symptoms of worn steering-bushes on a D22:
  • Vague on-centre feel or wander
  • Shimmy or knock over bumps
  • Visible idler arm play during inspection
  • Uneven tyre wear from inconsistent toe

Tip: Recheck fasteners after a few hundred kilometres and keep an eye on tyre pressures and alignment settings to get the best life from new bushes.

FAQs

Does a 1998 Navara have steering-bushes or rack bushes?
The 1998 D22 Navara uses a steering box, not a rack-and-pinion. That means no rack-mount bushes. Its key serviceable steering-bushes are in the idler arm, which supports the centre link opposite the pitman arm.

What are the signs the steering-bushes are worn on a 1998 Navara?
Owners often notice free play at the wheel, wandering on the highway, and a knock over potholes. A quick visual check will show the idler arm shifting sideways as the steering is rocked—classic worn-bush behaviour.

Rubber or polyurethane bushes for a D22—what’s better?
Rubber suits factory comfort and quietness. Polyurethane can sharpen response and last longer off-road, especially with a greaseable design. For a touring or work Navara, either is fine, choose based on ride preference and maintenance habits.
