Parts for your 1999 Nissan Navara-Wheel hubs

1999 Nissan Navara wheel hubs — what they do and how to look after them

Wheel hubs absolutely are used on the 1999 Nissan Navara (D22). Technical sources including the Nissan D22 Factory Service Manual (Front Axle and Rear Axle sections), Aisin documentation for free-wheeling/locking hubs, and bearing catalogues from major suppliers list front and rear hub and bearing assemblies for this ute. Four-wheel-drive models commonly run manual free-wheeling hubs (often Aisin) at the front, while 2WD uses a conventional hub and bearing arrangement. The rear is a semi-float live axle with pressed-on hub bearings.

The hub’s job is to locate the wheel securely on the axle, support vehicle load through the bearings, and allow smooth rotation. On 4WD Navaras with manual hubs, the hub also connects and disconnects the front wheels from the front axle to reduce drag and fuel use when not in 4WD. Where ABS is fitted, the hub/bearing may carry a tone ring for the sensor.

Servicing is straightforward if done on time. For typical Aussie and Kiwi conditions, front wheel bearings and hubs should be inspected every 40–60,000 km, or sooner if the Navara sees beach work, river crossings, farm dust, or towing. Water and grit are the enemies, they wash grease out and pit the bearing races.

• Tell-tale signs: a rumble that rises with speed, play felt at the wheel at 12 and 6 o’clock, uneven tyre wear, ABS warning (if equipped), or a hub running noticeably hotter than the others after a drive.
• Front hub care (4WD): check the free-wheeling hub engages and releases crisply, renew O-rings and gaskets if perished, clean and lightly grease the mechanism (don’t overpack). Repack tapered roller bearings with quality NLGI 2 wheel bearing grease and set preload per the factory spec. Always use new split pins and tighten fasteners to service manual torque values.
• Rear hub care: watch for axle seal weep onto the brake shoes or backing plate. Rear bearings are pressed onto the axle shaft, replacement needs a press and proper retainers, so a specialist shop is often the safe bet.

A fresh hub and bearing set keeps the Navara tracking straight, protects tyres, and stops that droning that makes highway runs a chore. Any doubt about noise or play, get it checked before a big trip—hub failures escalate quickly and can take brakes and studs with them.

Popular questions about 1999 Nissan Navara wheel hubs

Does a 1999 Navara have manual locking hubs?
Many D22 4WD models in this era were fitted with manual Aisin-style free-wheeling hubs, some markets had automatic hubs on certain trims. Two-wheel-drive models don’t have locking hubs, just standard front hubs and bearings.

How can someone tell if a front wheel bearing is worn?
Listen for a droning or growling that changes with road speed and may alter when weaving gently left and right. Jack the wheel, hold it at 12 and 6 o’clock, and feel for play. Any roughness or movement means it’s time for service or replacement.

How often should hubs and bearings be serviced?
As a rule of thumb, inspect every 40–60,000 km. If the ute does beach launches, water crossings, or corrugated tracks, shorten the interval and re-grease after any deep-water event. Always follow the D22 service manual procedures for preload and torque.
