Parts for your 2008 Nissan Navara-Universal joints

2008 Nissan Navara universal joints (U‑joints): purpose, servicing and replacement

Universal joints are absolutely fitted to the 2008 Nissan Navara (D40). Technical references including the Nissan Navara D40 Service Manual (Propeller Shaft/Driveline section), the Nissan FAST electronic parts catalogue, and common workshop guides (e.g., Gregory’s/Haynes) all show front and rear propeller shafts using single‑cardan U‑joints. Many models also run a two‑piece tailshaft with a centre bearing, again with U‑joints at each end to manage driveline angles.

On this ute, the U‑joints let the driveshaft transfer torque while the suspension moves and the angles between the gearbox/transfer case and differentials change. Without them, the driveline would bind and vibrate every time the load shifts, the tray is loaded, or the suspension cycles off‑road. For 4x4 Navaras, there’s a U‑joint at the rear propeller shaft and typically at the front prop shaft too, keeping things smooth in 2H, 4H and 4L.

Servicing is straightforward. Some factory joints are sealed-for-life, others and many aftermarket options have grease nipples. Either way, a quick inspection at each service (around 10,000–15,000 km) pays off—spin the shaft, feel for play, look for rust bleed at the bearing caps, cracked seals or dry, squeaky needle bearings. If it tows, carries heavy loads, or sees corrugations and beach work, give it extra attention and keep water crossings in mind—contamination is a fast track to wear.

• Typical warning signs: a clunk on take‑off or shift from reverse to drive, a chirp or squeal at low speed, and a steady vibration around 60–90 km/h that doesn’t feel like a tyre issue.
• Basic care: if greasable, add quality lithium complex or moly grease until fresh grease weeps from all four caps, wipe excess. Keep the slip joint lightly greased too.

When replacement time comes, mark the flanges and yokes so the shaft goes back in phase and stays balanced. Support the shaft, remove the circlips, and press the caps out with a vice or press—don’t belt on the yokes or you’ll distort them. Fit new circlips, check cap rotation is silky with zero notchiness, and torque the flange bolts to spec from the Nissan manual. Two‑piece shafts should be aligned to the arrows and the centre bearing checked for play and perished rubber. If the ute is lifted, ensure driveline angles remain within spec to protect the new joints. A short road test afterwards—light accel, coast, then load—will confirm it’s all sweet.

Quality U‑joints last ages when kept clean and lubricated. For hard‑working Navaras, greasable heavy‑duty joints are a tidy upgrade, provided they’re serviced on time.

Popular questions about 2008 Nissan Navara universal joints

How do you tell if the Navara’s U‑joints are worn?
Listen for a metallic clunk when shifting from reverse to drive, a chirp at low speeds, or a buzz/vibration under steady throttle. Under the vehicle, any free play at the caps, rust staining, or stiff movement across the joint points to replacement.

Are the factory D40 U‑joints greasable, and should they be upgraded?
Many OEM joints are sealed, some variants and most aftermarket replacements are greasable. If the ute tows, sees mud, or handles long corrugations, greasable HD joints are a smart upgrade—just remember to give them a pump at each service.

Can a home mechanic replace Navara U‑joints?
Yes, with basic tools: stands, a decent vice or press, and circlip pliers. Mark the yokes for phasing, use the workshop manual for bolt torques, and don’t hammer on the yokes. If you feel any residual vibration after, get the shaft checked for balance.
