Parts for your 2002 Daihatsu Gran move-Wheel bearings

2002 Daihatsu Gran Move wheel bearings — purpose and service advice

Wheel bearings are absolutely used on the 2002 Daihatsu Gran Move (also known in some markets as the Pyzar). Technical sources including the Daihatsu workshop manual for the Gran Move/Pyzar (Axle/Hub and Suspension sections), the Daihatsu Electronic Parts Catalogue (EPC) for the G3-series, and aftermarket catalogues from bearing manufacturers such as NSK/Koyo/SKF all list front wheel bearing units and rear hub bearings for 1997–2002 models. That makes wheel bearings directly relevant to servicing and repairs on a 2002 Gran Move.

On this model, the front end uses a sealed, double-row ball bearing pressed into the steering knuckle and hub. It carries vertical and cornering loads while allowing the wheel to spin smoothly, and on ABS-equipped variants the encoder ring or sensor interface lives at the hub. The rear end is drum-brake based and may be either a serviceable tapered roller arrangement with a grease seal and adjustable nut, or a sealed hub/bearing unit, depending on market specification. Either way, bearings are critical for quiet running, straight tracking, and even tyre wear.

There’s no fixed replacement interval, bearings are changed on condition. For a Gran Move that does school runs, weekend getaways and the odd corrugated Kiwi or Aussie backroad, regular checks during routine servicing are smart. A technician will spin the wheel by hand for roughness, feel for play at 12 and 6 o’clock, and listen for a speed-dependent hum on a road test. Heat at the hub after a short drive, grease weeping from a rear drum, or an ABS light (if equipped) can also point to bearing trouble.

Front bearings are non-serviceable, once noisy or rough they’re pressed out and replaced. The correct procedure includes supporting the inner and outer races properly during pressing, renewing the hub nut and any circlips, and keeping the ABS side clean. Rear serviceable types need fresh high-temp wheel bearing grease, a new seal, and the correct end-float/preload set with a new split pin. Quality parts from reputable brands are worth it, and after any bearing or hub work, a quick check of tyre pressures and alignment helps the lot last longer.

• Common symptoms: droning that rises with speed, play at the wheel, uneven tyre wear.
• Front = sealed cartridge, rear = serviceable taper roller or sealed hub (market dependent).
• Replace hardware (hub nut, split pin, seals) and avoid impact-loading the new bearing.
• If unsure, leave pressing and setup to a workshop with the right tools.

Popular questions

How can someone tell if the 2002 Gran Move’s wheel bearings are failing?
A steady rumble or drone that gets louder with road speed is the classic tell. Jacked up, the wheel may feel loose at 12 and 6 o’clock, or feel gritty when spun by hand. Heat at the hub after a short drive and, on ABS cars, a warning light can also be clues.

Are the front wheel bearings serviceable or do they need pressing?
The fronts are a sealed, pressed-in unit. They’re not repacked with grease, they’re replaced. Proper removal and installation with a press and correct supports is important to avoid damaging the new bearing or the knuckle, so most owners leave it to a workshop.

Should both wheel bearings be replaced at the same time?
Not mandatory. If one side is noisy, replacing that side only is fine, but it’s sensible to check the other side carefully. On high-kilometre vehicles used on rough roads, doing the pair can save a second trip if the mate is close behind.
