Parts for your 2000 Nissan Serena-Universal joints

2000 Nissan Serena universal joints: what’s fitted and how to look after them

Based on Nissan’s C24 Serena workshop information (Propeller Shaft/PD and Front Axle/FA sections) and the Nissan FAST electronic parts catalogue for the C24 series, universal joints (U‑joints) are not used on front‑wheel‑drive 2000 Nissan Serena models. Those variants use constant‑velocity (CV) joints on the front driveshafts. However, factory 4WD C24 Serena models have a rear propeller shaft that employs U‑joints at the front and rear flanges (and often a centre bearing), making U‑joints directly relevant for those vehicles.

Why aren’t U‑joints used on the 2WD Serena? The front‑drive layout needs joints that maintain constant angular velocity while steering and as the suspension moves. That’s the CV joint’s job, a single cardan U‑joint creates speed fluctuation at larger angles, which isn’t ideal for a front transaxle and steering geometry. Hence, FWD Serena = CV joints only, 4WD Serena = CV joints up front, U‑joints on the prop shaft down the back.

For 4WD 2000 Serena owners, the U‑joints live on the tailshaft, coupling the transfer/gearbox output to the rear differential. Their purpose is to transmit torque while allowing the shaft to operate at small angles as the driveline moves. Healthy U‑joints keep things smooth, worn ones cause vibration, clunks, and can take out a centre bearing or pinion seal if ignored.

Servicing is straightforward. During regular servicing (every 10,000–15,000 kilometres is a good rhythm), a technician should check each U‑joint for free play and roughness by unloading the shaft and feeling for notchiness. Sealed OE‑style joints often aren’t greaseable, if aftermarket greaseable joints are fitted, a couple of pumps of quality NLGI #2 lithium EP grease is enough—overfilling can pop the seals. Look for reddish dust around caps, missing circlips, sling marks from expelled grease, and any binding through the range of motion. Road test for tell‑tales.

• Common symptoms: a metallic clunk on take‑off or shifting from reverse to drive, a buzz or vibration that peaks at certain road speeds, chirping/squeaking that changes with vehicle speed, and driveline shudder under load.

Replacement is best done with the shaft marked for orientation to preserve balance. Unbolt the flanges, drop the shaft, press out the bearing caps, fit the new joint with clips seated fully, and keep the yokes correctly phased. Refit and torque fasteners to factory spec, then check the centre bearing and prop shaft runout. A quick recheck after a few hundred kilometres is a smart move. Leaving a failing U‑joint too long can escalate into damaged flanges, flogged pinion bearings, or even a dropped tailshaft, so timely attention saves money.

• Tips: keep tyres balanced (it helps diagnosis), replace in pairs if wear is similar, and always rule out engine/trans mounts before blaming the tailshaft.

Does a 2000 Nissan Serena have universal joints?

FWD 2000 Serena models don’t use U‑joints, they use CV joints on the front shafts. 4WD C24 models do have U‑joints on the rear propeller shaft. This layout is shown in the Nissan C24 workshop manual (Propeller Shaft/PD) and supported by the C24 FAST parts listings.

How long do the U‑joints last on a Serena 4WD?

Service life varies with use, but 150,000–250,000 kilometres is common. Frequent towing, gravel roads, or coastal conditions can shorten that. Regular inspections during routine servicing help catch dryness or play before vibration shows up.

Can failing U‑joints cause other damage?

Yes. Excess play can hammer the centre bearing, flog out flange holes, and load the rear diff pinion bearing. Severe cases can lead to tailshaft separation. Replacing a noisy joint early is far cheaper than repairing a driveline chain reaction.
