Parts for your 2013 Nissan Pulsar-Wheel bearings

2013 Nissan Pulsar wheel-bearings: what they do, when to replace, and why they matter

Yes, the 2013 Nissan Pulsar uses wheel-bearings. Technical sources including the Nissan Electronic Service Manual (ESM) for the 2013 Pulsar/Sentra (B17) and Pulsar hatch (C12), plus Nissan’s FAST parts catalogue, specify sealed hub-and-bearing units at the front, and sealed hub units at the rear (integrated with the rear drum on some grades, or with the rear disc hub on higher trims). These are non‑serviceable bearings that are replaced as complete assemblies.

On this Pulsar, wheel-bearings support the vehicle’s weight and let each wheel spin smoothly with minimal friction. They also keep the wheel located precisely so the tyres track straight and the ABS/ESC systems read wheel speed correctly (the tone ring or encoder is typically built into the hub). Because they’re sealed, there’s no routine greasing—when they wear out, the hub assembly is swapped.

Good wheel-bearings keep the car quiet and predictable, which helps tyres wear evenly and brakes feel consistent. Most owners will never think about them until symptoms pop up. Common signs include:

• A humming or growling that rises with road speed and often changes when gently weaving left–right
• Play or roughness when spinning the wheel off the ground
• ABS light faults from a damaged encoder ring or sensor interference
• Uneven tyre wear or vague steering feel

During regular servicing of a 2013 Pulsar, a mechanic will road test for bearing noise, check for play at 12–6 o’clock with the wheel raised, inspect for seal damage, and confirm there’s no brake drag that could mask a bearing issue. Because the assemblies are sealed, preventive maintenance is mostly about avoidance: don’t pressure-wash directly into hub seals, tighten wheel nuts with a torque wrench (not just a rattle gun), and avoid pothole hits that shock the hub.

When replacement is due, choose quality hub units (NTN, NSK, Koyo or genuine Nissan are common on these). Front hubs are a bolt-on unit on MacPherson strut knuckles, rears are a hub-and-bearing unit, integrated with the drum or disc. The job typically includes transferring the ABS sensor if separate, cleaning the mating face, torquing fasteners to spec, then a road test. There’s no routine adjustment—if a bearing is noisy or loose, replacement is the fix.

These details align with Nissan’s ESM procedures for “Front Axle” and “Rear Axle/Brake” sections and the FAST parts listings that identify unit-type, non-serviceable hub bearings on 2013 Pulsar models sold in Australia and New Zealand.

Popular question: Does the 2013 Pulsar have serviceable bearings or sealed hubs?

It uses sealed hub-and-bearing units front and rear. They’re not designed to be cleaned or repacked—when worn, the complete hub assembly is replaced. This matches Nissan ESM guidance and parts listings for B17 sedan and C12 hatch variants.

Popular question: How can someone tell which wheel-bearing is failing?

A speed-dependent hum that changes when gently steering is the giveaway. A mechanic will confirm by spinning each wheel off the ground and feeling for roughness, then checking for play. They may also use a chassis ear or NVH tool to pinpoint the noisy corner.

Popular question: How long do Pulsar wheel-bearings last, and is alignment needed after replacement?

Many last well past 150,000 km, but harsh roads, water ingress or impact damage can shorten life. Alignment isn’t usually required for a hub swap on this car, though it’s smart to check if the knuckle was disturbed or the vehicle already showed uneven tyre wear.
