Parts for your 1990 Nissan Primera-Centre bearing

1990 Nissan Primera centre-bearing — is it actually a thing on this model?

For the 1990 Nissan Primera (P10), a traditional prop shaft centre-bearing isn’t fitted on the vast majority of cars. Technical literature for the P10 platform identifies it as primarily front‑wheel drive (FF), which means there’s no rear differential and no long two‑piece prop shaft running down the car — the very setup that requires a centre-bearing. Factory sources such as the Nissan Primera P10 Factory Service Manual (Driveline/Axle section) and the Nissan FAST electronic parts catalogue list no propeller shaft or centre support bearing for standard FWD P10 models. General repair references (e.g., Haynes Primera 1990–1999) also describe all regular UK/EU/AU/NZ‑market 1990 cars as FWD without a prop shaft.

That’s why a “centre-bearing” isn’t used on a typical 1990 Primera: the drivetrain is a transverse engine with a front transaxle and two front driveshafts with CV joints. There’s simply nothing down the middle of the car that needs a centre support. Instead, what the Primera can have is a right‑hand intermediate driveshaft with a support (carrier) bearing bolted to the engine block. Some people casually call this a centre-bearing, but it’s a different part to the prop shaft centre support found on rear‑ or all‑wheel drive vehicles.

There is one caveat. A limited number of Japanese‑domestic P10 variants were built with 4WD. Those specific cars run a rear diff and a prop shaft, and may use a centre-bearing. They’re rare in Australia and New Zealand. If someone’s unsure which they’ve got, it’s easy to check:

• Look under the car for a prop shaft running to a rear differential
• Check the build plate/model code, 4WD variants differ from the common FWD “P10” codes
• Look for 4WD badging or rear diff housing

Chasing vibrations or droning on a FWD 1990 Primera? Skip the centre-bearing listing and focus on the usual suspects: front CV joints, the intermediate shaft support (carrier) bearing, tyre/wheel balance, and engine/trans mounts. Parts catalogues sometimes group “centre-bearing” across many models, but for a standard 1990 Primera FWD it’s not applicable.

Technical sources referenced: Nissan Primera P10 Factory Service Manual (1990, Driveline/Axle and General Information), Nissan FAST EPC for P10 model codes, and Haynes Repair Manual for Nissan Primera 1990–1999. These confirm FWD layout for standard 1990 models and no propeller shaft centre support bearing on those cars.

• Does a 1990 Nissan Primera have a centre-bearing?
  On standard FWD P10 models, no. There’s no prop shaft, so no centre-bearing is used. Only rare JDM 4WD variants might have one.
• What causes driveline vibration if there’s no centre-bearing?
  Most commonly worn CV joints, the RH intermediate shaft support (carrier) bearing, out‑of‑balance tyres/wheels, or tired engine/trans mounts.
• How can someone tell if their Primera needs a centre-bearing?
  If it’s 4WD with a rear diff and a prop shaft under the floor, yes. If it’s FWD only (typical in AU/NZ), a centre-bearing isn’t part of the car.
