Parts for your 2006 Nissan Serena-Universal joints

2006 Nissan Serena universal joints (UJ): what’s fitted and how to look after them

Technical references including the Nissan Serena C25 Electronic Service Manual (sections covering Front Axle and Propeller Shaft) and Nissan’s EPC/FAST parts catalogue show that 2006 Serena 2WD models use constant-velocity (CV) joints on the front driveshafts and do not have driveline universal joints. However, 4WD NC25 variants are built with a propeller shaft to the rear final drive that uses universal joints and a centre bearing. All variants also use a small universal joint on the steering intermediate shaft. So, universal joints are relevant for 4WD Serena driveline service, while 2WD owners will mainly encounter them on the steering column, not the axles.

On the 4WD 2006 Nissan Serena, the universal joints on the prop shaft let the shaft transfer torque to the rear diff while the suspension moves and the angles change. They’re simple, tough little couplings, but when they wear they can cause vibration and clunks that take the shine off an otherwise smooth family MPV. Most factory-fit UJs on these shafts are sealed (non-greaseable), so the usual approach is inspect-and-replace rather than periodic greasing.

During regular servicing, it pays to check for the classic signs:

• Shudder or humming between 60–90 km/h, especially on light throttle or overrun
• Clunk when shifting from reverse to drive
• Rusty “dust” at the bearing cap seals, or any looseness at the yokes

If any of that shows up, the fix is to remove the prop shaft, keep the yokes in phase (mark them before disassembly), and either press in quality replacement UJs or, where the original joints are staked and non-serviceable, fit a complete replacement prop shaft assembly. Reassembly should include new flange hardware where specified, threadlocker as required, correct torque on the flange bolts, and a check of the centre bearing rubber support. Because balance and phasing matter, many owners prefer having a driveline specialist handle pressing and balancing.

There’s no set kilometre interval for replacement, but UJs commonly last well past 150,000 km if the boots and seals stay intact. A quick underbody inspection every service is cheap insurance. For 2WD Serena models, the driveline doesn’t use UJs, instead, technicians should give the steering intermediate shaft UJ a wiggle check. Any notchiness, corrosion or play there usually calls for replacing the intermediate shaft assembly to keep the steering feel tidy.

Popular questions

Does a 2006 Nissan Serena have universal joints?
Yes for 4WD (NC25) models on the propeller shaft to the rear diff, plus a small UJ on the steering intermediate shaft across all variants. The 2WD driveline uses CV joints on the front axles and doesn’t have driveline UJs.

How long do the Serena’s UJs last, and when should they be replaced?
They often run 150,000–250,000 km or more. Replace if there’s vibration at speed, a clunk on take-up, visible rust dust at the caps, or any play. Because most factory UJs are sealed, the remedy is replacement rather than greasing.

Can the universal joints be greased?
Most OEM UJs on the Serena prop shaft are sealed and non-greaseable. Some aftermarket replacements include grease nipples, if those are fitted, a light grease at routine intervals helps longevity.
