Parts for your 1988 Mitsubishi Pajero-Centre bearing

1988 Mitsubishi Pajero centre-bearing — what it does and when it’s needed

Technical sources confirm that a centre-bearing (also called a tailshaft centre support bearing) is used on 1988 Mitsubishi Pajero long‑wheelbase (LWB) models with a two‑piece rear propeller shaft, while short‑wheelbase (SWB) models run a single‑piece shaft and therefore don’t have a centre-bearing. See: Mitsubishi Pajero/Montero 1983–1991 Workshop Manual, Group 22 Propeller Shaft, Gregory’s Service & Repair Manual Mitsubishi Pajero 1983–1996 (Australia), Driveline chapter, and the Mitsubishi ASA Electronic Parts Catalogue for L040-series Pajero, which lists a “centre bearing support” for LWB variants.

For the LWB 1988 Pajero, the centre-bearing’s job is to support the two‑piece tailshaft, keeping driveline angles tidy and vibrations at bay. It sits mid‑ship on a bracket, with a rubber isolator and a sealed bearing that carries the shaft under load. On tourers and tow rigs, it’s a quiet achiever—until it isn’t. When the rubber cracks or the bearing wears, owners start to feel a shudder on take‑off, a drone at 60–80 km/h, or a clunk as the torque loads and unloads.

As part of regular servicing on a 1988 LWB Pajero, it’s smart to give the centre-bearing a once‑over every 20,000 km (or sooner if it works hard off‑road). Look for perished rubber, sagging in the carrier, or any play when the tailshaft is lifted by hand. Spin the shaft and listen for roughness. If there’s vibration under acceleration that eases when you back off, the bearing deserves attention.

Replacement isn’t tricky for a competent home mechanic, but care matters. Always:

• Mark the tailshaft flanges and yoke phasing before removal to preserve balance and alignment.
• Support the shaft to avoid over‑stretching the slip joint.
• Inspect uni joints while the shaft is out, replace if notchy or loose.
• Install the new centre-bearing in the correct orientation and set the carrier so the shaft runs true (slight preload as specified by the workshop manual).
• Recheck driveline angles if the vehicle has a lift—steeper angles shorten bearing life.

Quality OEM‑equivalent bearings and carriers are worth it, cheap rubber can collapse early. After refit, road test for any lingering vibration and re‑torque fasteners after a few heat cycles. For SWB owners wondering why there’s no centre-bearing: the single‑piece shaft is short enough to control critical speed and alignment without mid‑support, keeping the setup lighter and simpler with less to maintain.

Popular questions about 1988 Mitsubishi Pajero centre-bearing

Does every 1988 Pajero have a centre-bearing?
No. LWB models with a two‑piece tailshaft do, SWB models with a single‑piece shaft don’t. A quick look under the middle of the vehicle will reveal a carrier bracket on LWB versions.

What symptoms point to a failing centre-bearing?
Typical signs include a shudder on take‑off, a low‑frequency drone at highway speeds, and visible cracking or sagging of the rubber carrier. Excess play when you lift the tailshaft near the carrier is another giveaway.

Can it be replaced at home?
Yes, with stands, hand tools and care. Mark the shaft for phasing, check the uni joints while it’s apart, and fit the carrier correctly aligned. If vibration persists after replacement, revisit shaft balance and driveline angles.
