Parts for your 1998 Nissan Pulsar-Centre bearing

1998 Nissan Pulsar centre-bearing — what owners should know

For the 1998 Nissan Pulsar (N15 series), a centre-bearing isn’t fitted or required. The Pulsar is front-wheel drive with a transaxle up front, two short drive shafts (CV axles), and no long, two-piece tailshaft running to a rear differential. Centre-bearings are the mid-support bearings used on two-piece prop shafts in rear-wheel drive or 4WD vehicles, so they simply don’t apply to this model.

This isn’t just hearsay. The Nissan Pulsar N15 Factory Service Manual (Driveline/Front Axle sections) details CV axles and the transaxle layout and has no “propeller shaft” or centre support bearing. The Nissan FAST parts catalogue for N15 likewise shows no prop shaft group for this chassis. General workshop manuals for the era (e.g., Haynes/Gregory’s covering Pulsar/Sentra 1995–2000) also describe a purely FWD driveline with no centre-bearing.

Where confusion creeps in is the right-hand (long) side on some Pulsar variants that use an intermediate (half) shaft with a support bearing bolted to the engine block. That part is a driveshaft support bearing, not a tailshaft centre-bearing. It sits at the engine/gearbox end on the passenger side, not in the middle of the car, and it services the front driveshaft only.

So if a 1998 Pulsar owner is chasing a rumble or vibration, it’s more likely to be one of the usual FWD suspects:

• Outer or inner CV joints clicking or vibrating on load
• RH intermediate shaft support bearing (if fitted) humming at road speed
• Front wheel bearings, tyres out of balance, or flat-spotted
• Engine or transmission mounts collapsed and transmitting vibration

Bottom line: a centre-bearing isn’t used on the 1998 Nissan Pulsar because there’s no two-piece prop shaft to support. Any catalogue line item labelled “centre-bearing” for this model is either a generic listing or actually referring to the RH driveshaft support bearing on variants that have an intermediate shaft.

FAQs

Does a 1998 Nissan Pulsar have a centre-bearing?
No. The N15 Pulsar is front-wheel drive and doesn’t use a two-piece prop shaft, so there’s no centre support bearing in its driveline. Factory manuals and the Nissan parts catalogue for N15 confirm there’s no propeller shaft or centre-bearing assembly.

What bearing are people talking about if they say “centre-bearing” on a Pulsar?
They’re usually referring to the right-hand driveshaft’s intermediate (half) shaft support bearing on some variants. It’s bolted to the engine block and supports the longer front shaft. Different part, different job, and not located in the centre of the vehicle.

What should be checked for vibrations on an N15 Pulsar?
Start with the front CV joints, front wheel bearings, tyre condition and balance, then engine and transmission mounts. If your variant has the RH intermediate shaft, listen for a constant-speed hum that changes with road speed—this can point to a tired support bearing.
