Parts for your 1999 Mitsubishi Pajero-Centre bearing

1999 Mitsubishi Pajero centre-bearing

Technical references show a centre support bearing is used on the 1999 Mitsubishi Pajero long‑wheelbase (5‑door) models because they run a two‑piece rear propeller shaft, the short‑wheelbase (3‑door) typically uses a single‑piece shaft and doesn’t have a centre bearing. This is documented in the Mitsubishi Pajero/Montero Workshop Manual (1997–1999), Group 22A Propeller Shaft (two‑piece type with centre support bearing for LWB), the Mitsubishi ASA electronic parts catalogue for late NL/early NM models (centre support bearing listed under the rear propeller shaft for LWB), and general service manuals such as Haynes/Gregory’s covering Pajero/Montero up to 2000, which describe inspection and renewal of the centre support bearing on long‑wheelbase vehicles.

On long‑wheelbase 1999 Pajeros, the centre‑bearing’s job is to support the two‑piece tailshaft midway, keeping driveline angles tidy and vibrations at bay. It sits in a rubber carrier (the “hanger”), bolted to a crossmember, letting the shaft spin smoothly while soaking up movement from the chassis and suspension. It’s a simple bit of kit that makes a big difference to NVH and drivetrain longevity, especially on lifted or heavily loaded rigs that clock up outback or off‑road kilometres.

As part of servicing, it’s worth giving the centre‑bearing a look every 20,000 km or during scheduled underbody checks. A quick visual inspection will usually tell the story: look for perished or torn rubber in the hanger, off‑centre sag, or contact marks where the shaft has been moving about. On a road test, take note of a dull thump on take‑off, a shudder between 40–70 km/h under load, or a droning vibe that eases when you lift off — all classic centre‑bearing/redriveshaft clues. While under the vehicle, also check uni joints, slip‑yoke play, and tailshaft phasing.

Replacement is straightforward for a competent tech: mark the flanges and shaft for re‑assembly, drop the tailshaft, press off the old bearing, then press on the new unit with correct orientation. Refit using new locknuts where specified, set the support bracket square without pre‑loading the rubber, and torque to spec from the service manual. If the shaft has been separated or shows witness marks, have it balanced. On Super Select models, a post‑service road test across 2H/4H to check for residual vibration is smart practice.

A healthy centre‑bearing keeps the Pajero smooth on the highway and kinder to the transfer case and diffs. If the vehicle is lifted or regularly tows, more frequent checks are a good shout.

• Common signs: take‑off clunk, mid‑range vibration, cracked/sagging rubber, roughness when rotating the shaft by hand.
• Good practice: mark and refit in phase, verify angles after suspension mods, and balance the shaft if any doubt.

FAQs

Does a 1999 Mitsubishi Pajero have a centre‑bearing?
Yes on long‑wheelbase (5‑door) models with a two‑piece rear prop shaft. Short‑wheelbase (3‑door) versions often run a single‑piece shaft and don’t use a centre support bearing.

What are the symptoms of a worn centre‑bearing on a 1999 Pajero?
Expect a take‑off thump, shudder under load between about 40–70 km/h, and a droning vibration that eases when you back off. Underneath, the rubber hanger may be cracked or sagging, and the shaft can feel sloppy.

Is it safe to keep driving with a noisy or sagging centre‑bearing?
It’ll usually get you home, but continued driving can accelerate wear in uni joints, output seals and even the transfer case. Best to sort it promptly and avoid heavy towing or high speeds until it’s fixed.
