Parts for your 1991 Nissan Primera-Wheel hubs

1991 Nissan Primera (P10) wheel hubs — what they do and how to look after them

Yes, the 1991 Nissan Primera definitely uses wheel hubs. Technical sources including the Nissan Primera P10 Factory Service Manual (Front Axle – FAX section and Rear Axle – RAX section) and the Haynes Nissan Primera 1990–1999 manual confirm that this model runs conventional hubs at the front and rear. Up front, the hub is pressed into a double‑row ball bearing in the steering knuckle, at the rear, models vary between a bolt‑on hub/bearing unit or a hub with an internal bearing, with ABS versions adding a tone ring.

The hub’s job is simple but critical: it’s the sturdy mounting that the wheel bolts to, it keeps the brake disc centred, and on the front it transfers drive from the CV shaft. The bearing supports vehicle weight and lets the wheel spin smoothly, while the hub carries the wheel studs and, where fitted, the ABS trigger. When a hub or bearing wears, you’ll notice roughness, noise, or vague steering — and that’s when it’s time to sort it.

As part of regular servicing on a 1991 Primera, it’s smart to check for play and noise. Spin each wheel by hand off the ground and listen for a growl, and rock the wheel at 12 and 6 o’clock for movement. A quick road test for a humming that changes with speed or a rumble in sweeping bends also helps pick early wear. Catching issues early saves tyres and brakes, and keeps the ABS happy.

• Common signs it’s due: humming or droning with speed, ABS light with no sensor fault, uneven tyre wear, brake pad knock-off, or heat at the hub after a drive.
• Front bearing service uses a press: the bearing is pressed into the knuckle and the hub is pressed into the bearing. Rear may be a bolt‑on unit on some trims.
• Always use a new axle nut and circlip where specified, torque to the factory spec from the FSM, and don’t preload the bearing incorrectly.
• Protect the ABS sensor and tone ring, set the correct sensor gap and clear any rust on the mounting face so the disc runs true.
• If the front knuckle is removed, organising a wheel alignment is a good shout.

Replacement is usually done per side as needed. If the hub journal is pitted or the wheel studs are flogged out, replace the hub along with the bearing. Quality bearings and proper torque go a long way to getting many more kilometres of quiet running.

FAQs

Does a 1991 Nissan Primera have wheel hubs?
Yes. Factory documentation (Nissan P10 FSM, sections FAX and RAX) and the Haynes manual detail front hubs pressed into double‑row bearings and rear hub/bearing setups, with ABS tone rings on equipped models.

What are the symptoms of a bad hub or bearing on a P10?
Think humming that increases with road speed, a rough feel when spinning the wheel off the ground, play at the rim, ABS warnings without a sensor fault, or heat at the hub after a short drive.

Do you need an alignment after replacing a hub?
If the front steering knuckle was removed or loosened during the job, a wheel alignment is recommended. If it’s a simple rear bolt‑on hub unit and nothing in the suspension was disturbed, alignment usually isn’t required.
