Parts for your 2012 Nissan Pulsar-Universal joints

2012 Nissan Pulsar universal joints: what’s actually fitted

For the 2012 Nissan Pulsar (C12 hatch and B17 sedan sold in Australia and New Zealand), traditional driveline universal joints (Cardan U‑joints) aren’t used. These models are front‑wheel drive with transverse engines, so they run front drive shafts with constant‑velocity (CV) joints rather than a tailshaft with U‑joints. The only “universal” type joint you’ll typically find is a small U‑joint on the steering intermediate shaft.

That conclusion aligns with technical literature: Nissan’s Electronic Service Manual (ESM) for the C12/B17 shows front drive shafts using Rzeppa/tripod CV joints under Axle/Driveshaft sections, with no propeller shaft or tailshaft U‑joints specified, the Steering (ST) section lists an intermediate shaft with a U‑joint. General drivetrain references such as the Bosch Automotive Handbook also note that front‑wheel‑drive layouts use CV joints to maintain constant angular velocity at larger steering and suspension angles, where Cardan U‑joints would introduce speed fluctuation and vibration.

Why U‑joints aren’t used on the Pulsar’s driveline:

• Packaging and layout: there’s no longitudinal prop shaft on a FWD Pulsar, so there’s nowhere for tailshaft U‑joints to live.
• Driveability: CV joints keep the output speed constant through big steering angles, reducing torque steer and shudder that a single Cardan joint can cause.
• NVH and durability: CV joints better handle the articulation and plunge needed with MacPherson struts and road movement at the front axle.

What owners should service instead:

• CV joints and boots: inspect at each service (around 10,000–15,000 km). Look for split boots, slung grease on the inside of the front wheels, clicking on tight turns, or vibration under load. Replace boots early to save the joint.
• Steering intermediate shaft U‑joint: check for corrosion, stiffness, or free play if the steering feels notchy or has a tight spot. Replace the shaft if there’s binding or lash, it’s not a lubricate‑in‑situ item.
• Related items: front hub seals and wheel bearings for noise or play, alignment and tyre condition if vibration persists after CV checks.

FAQs

Does a 2012 Nissan Pulsar have universal joints in the driveline?
No. The driveline uses CV joints on the front drive shafts. A small U‑joint is present on the steering intermediate shaft, but there’s no tailshaft or rear prop with U‑joints on these FWD models.

What are the signs of a failing joint on a Pulsar?
For CV joints: clicking or clacking on full lock, grease flung around the inner wheel/guard, vibration on acceleration, or a torn boot. For the steering U‑joint: notchiness, stiffness at certain wheel angles, or free play in the column.

What should be serviced and how often?
Have the CV boots and joints inspected at regular services (about every 10,000–15,000 km). Replace any split boots promptly. Check the steering intermediate shaft for corrosion or play annually or if the steering feel changes.
