Parts for your 2001 Nissan Navara-Wheel hubs

2001 Nissan Navara wheel hubs — what they do and how to look after them

Wheel hubs are absolutely used on the 2001 Nissan Navara (D22). Technical references such as the Nissan Navara D22 Factory Service Manual (Front Axle and Rear Axle sections) and the Haynes manual covering Nissan Pick-up/Frontier/Navara 1998–2004 confirm the model’s use of conventional wheel hubs with serviceable taper-roller bearings at the front, and hub/flange arrangements at the rear. On 4x4 variants, the front hubs incorporate freewheeling/locking mechanisms to engage the front drivetrain.

On this Navara, the hub’s job is to carry the wheel, house the bearings, and allow smooth rotation under load. For 4x4 models, the front hub also connects or disconnects the front axles, reducing drag and fuel use when left in “FREE”. Whether it’s manual locking hubs (common on AU/NZ D22s) or auto/freewheeling types, a healthy hub keeps steering tidy, braking consistent, and tyres wearing evenly.

Typical warning signs include a humming or growl that rises with road speed, looseness when rocking the wheel at 12 and 6 o’clock, heat at the hub after a drive, grease leakage at the seal, ABS warnings (if fitted), or uneven tyre wear. If a locking hub is reluctant to click between FREE and LOCK, or the dial feels gritty, it’s due for a clean and re-lube.

• Inspection and service: Check hub bearings at brake pad/rotor service intervals or every 20,000–40,000 km. Clean, repack with a quality high-temp wheel bearing grease (NLGI 2), and fit new seals.
• Adjustment: Front taper-roller bearings need correct preload and end float set per the factory manual. Use the proper lock nut arrangement and a fresh split pin.
• Locking hubs: Strip, clean, and lightly grease the cam and splines. Avoid packing the dial full of grease
