Parts for your 2002 Nissan Navara-Rack boots

2002 Nissan Navara rack-boots — are they used, and what to service instead

For the 2002 Nissan Navara (D22, AU/NZ models), rack-boots are not used. Technical sources show this model runs a recirculating-ball steering box with a relay rod (centre link), pitman arm, idler arm and tie-rod ends, rather than a rack-and-pinion setup. Because there’s no steering rack, there are no rack-boots to fit.

References to back this up include:

• Nissan Navara/Frontier D22 Workshop/Service Manual – Steering (ST) section: identifies a ball-nut (recirculating-ball) steering gear, relay rod, idler arm and tie-rods, with no rack-and-pinion assembly or rack gaiters.
• Nissan FAST electronic parts catalogue for D22 (circa 2002): lists steering gear box, centre link, idler arm and tie-rod components, no “rack boot/rack gaiter” part is catalogued for this platform.
• Common AU/NZ aftermarket fitment guides for 2002 D22: show idler arm, tie-rod ends and their dust boots, but do not list rack boots for D22 vehicles.

So what’s actually doing the sealing? On the D22, the protective rubbers are the dust boots on the tie-rod ends and idler arm, plus seals within the steering box itself. Those little boots keep grit and water out of the joints so they don’t wear out in a hurry. If a catalogue shows “rack boot” against a 2002 Navara, it’s usually a generic listing or a fitment error.

Good servicing for a 2002 Navara’s steering looks like this:

• Inspect tie-rod end dust boots and the idler arm boot for splits, perishing or grease weep. Replace the joint if the boot has failed.
• Check the idler arm bush for play and the pitman/relay rod joints for looseness, off-road use can accelerate wear.
• Look for steering box leaks at the input and sector shaft seals, address promptly to avoid contamination and free-play.
• After any steering component replacement, get a wheel alignment to preserve tyre life and handling.

Owners chasing tighter steering feel will usually get the best results by renewing worn tie-rods, the idler arm assembly and setting correct wheel alignment, rather than hunting for non-existent rack-boots.

Popular questions about 2002 Nissan Navara rack-boots

Does a 2002 Navara have rack-boots?
No. The D22 uses a recirculating-ball steering box and linkages, not a rack-and-pinion. That means there’s no steering rack and therefore no rack-boots on this model.

What boots should be checked instead on a 2002 Navara?
Check the dust boots on the tie-rod ends and the idler arm, and keep an eye on the steering box seals. If any boot is split or weeping, the joint is on borrowed time and should be replaced to avoid sloppy steering and uneven tyre wear.

Can a 2002 Navara be converted to rack-and-pinion?
It’s not a straightforward or common swap. Conversions would need custom engineering, certification and may affect compliance. Most owners get better value by refreshing the factory steering components and ensuring alignment is spot-on.
