Parts for your 2011 Nissan Pathfinder-Centre bearing

2011 Nissan Pathfinder centre-bearing: what it does and how to look after it

Based on the Nissan R51 Pathfinder Service Manual (DLN – Propeller Shaft) and the Nissan Electronic Parts Catalogue (FAST, Group 37: Propeller Shaft), the AU/NZ‑spec 2011 Pathfinder (R51) runs a two‑piece rear propeller shaft with a factory‑fitted centre support bearing. Some owners convert to an aftermarket one‑piece tailshaft, which removes the centre‑bearing, but as built from the factory the 2011 Pathfinder uses one.

The centre‑bearing’s job is to support the long, two‑piece tailshaft, keeping it aligned under load and at highway speeds. It helps control driveline angles, reduces vibration, and protects the universal joints and gearbox/transfer case from extra stress. On an R51 that tows, sees corrugations, or has a lift kit, the centre‑bearing works even harder, making regular checks worthwhile.

What owners and workshops should look for during routine servicing:

• Inspect the rubber support for cracks, separation, or sagging.
• Spin and feel the bearing for roughness or notchiness, listen for droning or rumbling on test drive (often 60–90 km/h under light throttle).
• Check for tailshaft shudder on take‑off or a dull clunk on throttle changes, which can also implicate the bearing or uni joints.
• Verify mount bolts are tight and the carrier isn’t distorted, look for witness marks that suggest misalignment.

Replacement is straightforward for a driveline specialist and a reasonable DIY for the experienced: remove the tailshaft, mark phasing, separate the halves, press off the old bearing and carrier, press on the new assembly, then refit and torque to spec. It’s smart to assess the universal joints at the same time and rebalance the shaft if there’s any doubt. After install, set the vehicle on its wheels at ride height before final torquing so the rubber support sits in a neutral position.

Tips that help Pathfinders run smooth:

• Inspect every 10–15,000 km, replace when rough, noisy, or when the rubber support sags or tears.
• If the vehicle is lifted or has altered driveline angles, consider shimming/adjustment to keep the tailshaft geometry happy.
• Use quality bearings and carriers that suit the R51, mixing parts across models can upset balance and phasing.

When the centre‑bearing is healthy, the R51 feels calmer on the motorway, tows better, and protects the rest of the driveline from costly wear.

Popular questions

Does every 2011 Pathfinder have a centre‑bearing?
Yes, factory‑spec R51 Pathfinders in Australia and New Zealand use a two‑piece rear prop shaft with a centre‑bearing. The only time you won’t find one is if a previous owner has fitted a one‑piece tailshaft conversion, which deletes the carrier.

What are the symptoms of a failing centre‑bearing on an R51?
Common signs include a humming or droning noise that rises with road speed, a shudder on take‑off, vibration around 60–90 km/h, and visible cracking or sagging of the rubber support. It can also contribute to clunks on throttle changes if the internal bearing is sloppy.

Is it safe to keep driving with a noisy centre‑bearing?
Short term, you may get by, but it’s not ideal. A failing centre‑bearing can accelerate wear in the universal joints and stress the gearbox/transfer case mounts. If noise or vibration is present, plan a replacement soon to avoid bigger bills.
