Parts for your 2004 Nissan Navara-Wheel bearings

2004 Nissan Navara wheel bearings — what they do and when to service them

Technical sources confirm wheel bearings are absolutely used on the 2004 Nissan Navara. The Nissan Navara D22 Workshop Manual (Front Axle “FAX” and Rear Axle “RAX” sections) details front hub bearing adjustment and rear axle bearing replacement procedures, and the D40 manual for early 2004-on models covers the same. Common aftermarket manuals and dealer parts catalogues for the 2004 Navara list inner/outer front bearings and a pressed-on rear axle bearing with oil seal. So wheel bearings are relevant, fitted front and rear on both 2WD and 4WD variants.

On the 2004 Navara, the front end typically runs serviceable tapered roller bearings inside the hub, while the rear uses a sealed bearing pressed onto the axle shaft with a retainer and axle oil seal. Their job is simple but critical: keep the wheels spinning smoothly with minimal friction, carry vehicle and cornering loads, and hold accurate wheel alignment so tyres wear evenly and braking stays consistent. When bearings get dry, contaminated or worn, they can hum, grind or allow wheel play, which can snowball into warped rotors, uneven tyre wear, and—if ignored—hub or axle damage.

For routine servicing, front bearings deserve a clean, inspection and high-temp grease repack at sensible intervals—every 40,000–60,000 km is a good rule of thumb for a D22 used on Aussie or Kiwi roads, sooner if it tows, does beach work, tackles water crossings or spends time in bulldust. After repacking, they need correct preload and new hub seals, follow the Navara workshop manual procedure and torque specs for the lock nut and stake/retainer setup. If the races are pitted or blue from heat, replace the bearing set and races as a pair.

Rear bearings are sealed units. There’s no greasing—just inspect for rumbling noises that rise with speed, axle-end play, or diff oil weeping past the axle seal. Replacement requires pulling the axle, pressing off the retainer, bearing and seal, and installing new parts with the correct orientation and press load. Most workshops will also renew the axle seal and retainer collar at the same time to keep things tight and leak-free.

• Watch for: humming that changes on sweepers, ABS flickers, heat at the hub, or play at 12 and 6 o’clock.
• Good practice: quality bearings and seals, fresh grease on fronts, and alignment/tyre check after any bearing job.

Popular questions

How do you tell if a 2004 Navara front wheel bearing is on the way out?

Listen for a speed-related hum or growl that gets louder when loading that corner (e.g., turning right makes a left-front noise louder). Jack the wheel, hold at 12 and 6 o’clock and feel for play or roughness when spinning. Any gritty feel, heat after a drive, or grease escaping the hub seal points to service or replacement.

How often should the front bearings be repacked on a D22 Navara?

For mixed on-road use, every 40,000–60,000 km works well. If the ute tows, sees river crossings, corrugations, or beach sand, shorten the interval. Always replace the hub seal and set preload per the workshop manual after repacking.

Do the rear wheel bearings need greasing?

No. The rear bearings on the 2004 Navara are sealed and non-serviceable. If they’re noisy or leaking, the fix is press-off/press-on replacement along with a new axle oil seal and retainer.
