Parts for your 1994 Nissan Primera-Wheel bearings

1994 Nissan Primera wheel-bearings — what they do and when to replace

According to technical references such as the Nissan Primera P10 Factory Service Manual (1990–1996) — Front Axle (FA) and Rear Axle sections — and the Nissan FAST parts catalogue, the 1994 Nissan Primera is fitted with wheel-bearings front and rear. The front uses a hub bearing pressed into the steering knuckle, while the rear is either a sealed hub unit (common on disc-brake variants) or a serviceable tapered roller set on some drum-brake setups, depending on market and spec.

Wheel-bearings let the wheels spin freely while carrying the car’s weight and cornering loads. They keep friction low, help maintain precise wheel alignment, and on ABS-equipped cars often carry the tone ring the sensor reads. When bearings wear, they can rumble, growl, or drone, particularly at certain speeds or when loading the car in a bend. Letting them go too long risks heat build-up, damaged hubs, and uneven tyre wear.

For the 1994 Primera, there’s no strict replacement interval. Many last 150,000–250,000 km, but it really comes down to use, road conditions, and previous repairs. Sealed bearings aren’t serviceable — if they’re noisy or rough, replace them as a unit. Tapered roller rears (where fitted) should be cleaned, inspected, and repacked with a quality high-temp wheel-bearing grease whenever the rear brakes are serviced, and the grease seal replaced if disturbed.

• Common signs they’re due: humming that rises with speed, play felt when rocking the wheel at 12 and 6 o’clock, ABS warning (if the tone ring is affected), or a hot hub after a drive.
• When replacing: use a press and support the hub correctly so the new bearing isn’t loaded through the balls/rollers
