Parts for your 1991 Nissan Primera-Universal joints

1991 Nissan Primera universal joints — are they even a thing?

Based on factory and aftermarket technical references, universal joints (Cardan U-joints) are not a driveline item on a standard 1991 Nissan Primera (P10). The Nissan Primera P10 Factory Service Manual details front drive shafts with inner tripod and outer Rzeppa constant velocity (CV) joints for the front-wheel-drive layout, and its propeller shaft section applies only to rare 4WD variants. The Nissan FAST electronic parts catalogue for typical FWD P10 VINs lists no propeller shaft or U-joint assemblies, and the Haynes/Autodata coverage for 1990–1999 Primera likewise shows CV-equipped front axles without traditional U-joints. That all points to “no” for U-joints on the usual 1991 Primera sold in most markets.

Why aren’t U-joints used here? In a FWD car like the P10, the front axles need to transmit drive while steering and moving through suspension travel. CV joints maintain constant rotational speed through large angles, keeping things smooth and quiet. Traditional U-joints create speed fluctuations at angle, which is fine on a straight prop shaft but not on a steered front axle, so Nissan used CVs instead.

There are a couple of caveats. Some niche-market P10 4WD/ATTESA models exist, those can have a propeller shaft to the rear diff that may use conventional U-joints (or a CV-style coupling) and a centre support bearing. Those cars were uncommon, and parts are often serviced as complete assemblies. Also, the steering column uses a small universal joint in the intermediate shaft, but that’s part of the steering system, not the driveline “universal joint” most people mean.

For owners chasing a knock or vibration, the smart play is to focus on the CV joints and boots. Split boots fling grease and quickly chew out a joint, especially the outer CV, which then clicks on full lock. Inner CV wear is more likely to cause shudder under load. Keep an eye on boot condition, use the right high-moly CV grease, fit proper clamps, and have axle nuts torqued to spec after any work.

• Typical signs to watch: grease spray around the inner guard, clicking on turns, shudder on acceleration, or torn boots.
• If in doubt about 4WD fitment, check the VIN/build plate or look underneath for a prop shaft and rear diff.

FAQs

Does a 1991 Nissan Primera have universal joints?
For the common front-wheel-drive P10, no driveline U-joints are fitted — it uses CV joints on the front axles. There is a small universal joint in the steering intermediate shaft, but that’s part of the steering column, not the propulsion system.

What should be serviced instead of universal joints on a 1991 Primera?
Focus on the CV joints and boots. Inspect boots regularly, replace any split or perished boots promptly, and listen for clicking on full lock (outer CV) or vibration under load (inner CV). Many shops will replace the whole driveshaft if a joint is noisy or badly worn.

Could my Primera have U-joints if it’s a 4WD?
Some rare P10 4WD/ATTESA models may use a propeller shaft with conventional U-joints or CV couplings. If the car has a rear differential and a centre prop shaft, it’s not the usual FWD setup. Parts for those cars can differ and are often serviced as assemblies, so confirm by VIN before ordering.
