Parts for your 2012 Nissan Navara-Universal joints

2012 Nissan Navara universal joints (U‑joints): purpose, service and replacement

Universal joints are absolutely fitted to the 2012 Nissan Navara (D40). Technical sources including the Nissan Navara D40 Factory Service Manual (propeller shaft/driveline sections) and Nissan’s FAST parts catalogue for MY2012 list cross‑and‑bearing universal joints on the rear propeller shaft, and on the front propeller shaft for 4WD models. Many AU/NZ D40 utes also use a two‑piece tailshaft with a centre bearing, flanked by U‑joints.

The U‑joint’s job is simple but vital: it lets the tailshaft run at an angle between the gearbox or transfer case and the diff while still delivering torque smoothly. As the suspension works and the driveline angles change, the needle‑bearing caps in each joint allow the yokes to articulate and keep the rotation consistent. Correctly phased and in good nick, they keep vibrations down and protect the rest of the driveline.

From the factory, most D40 U‑joints are sealed, non‑greaseable types. That means there’s no regular greasing point, but they should still be checked at every service. A quick inspection at 10,000–15,000 km intervals is smart—spin the shaft, feel for roughness or binding, look for rusty “tea stains” at the caps, perished seals, or fling marks from escaping grease. Any free play when the shaft is twisted by hand is a red flag. Water crossings, beach work, big tyres, or a lift kit? Bump inspections up, because angles and contamination shorten life.

When a U‑joint is worn, replacement is the fix. The D40 manual notes some joints are staked from the factory, Nissan’s service approach is often to replace the shaft assembly. In practice, quality aftermarket joints with circlips are widely used. The key is matching the correct cap diameter and span for the specific VIN, marking yokes before disassembly to keep the shaft in phase, using a press or suitable tools (no hammering the needles), and torquing flange hardware to Nissan specifications with new self‑locking nuts. After refitting, check phasing marks, road‑test for vibes, and re‑inspect. If the ute sees lots of water or off‑road, many owners prefer greaseable replacements and give them a pump after dunkings.

• Common symptoms of a tired U‑joint: a take‑off clunk, a speed‑related vibration (often 60–90 km/h), a chirp/squeak at low speed, visible play at the caps, or hot bearing caps after a run.

Are the universal joints on a 2012 Navara serviceable or sealed?

Most factory D40 U‑joints are sealed “lube‑for‑life” units without grease nipples. Some variants and many aftermarket replacements are greaseable. If the originals are staked in, workshops often either fit quality circlip‑type joints or replace the complete shaft, depending on condition and budget.

Greaseable joints are handy for utes that tow, beach‑drive or ford creeks. A quick pump after water exposure helps push out moisture and grit, extending life.

How long do the U‑joints usually last?

On mostly on‑road Navaras, it’s common to see 150,000–200,000 kilometres before noticeable wear. Heavy towing, lifted suspension, misalignment, or frequent water and dust can cut that dramatically. Listening for squeaks, watching for vibrations, and checking for play at each service will catch issues early and save the centre bearing and diffs from extra stress.

What U‑joint size does my 2012 Navara use?

It depends on drivetrain (2WD vs 4WD), engine, and whether the tailshaft is one‑ or two‑piece. The safest way is to confirm by VIN in the parts catalogue and, if needed, measure cap diameter and overall span after removal. This ensures the replacement matches the yoke and retains proper balance and phasing.
