Parts for your 2009 Toyota Hilux-Centre bearing

2009 Toyota Hilux centre-bearing: fitment, purpose, and service tips

According to Toyota’s AN10/AN20 series workshop manual (Propeller Shaft section) and the Toyota Electronic Parts Catalogue for KUN/GGN25–26 models, most 2009 Hilux Dual Cab and Extra Cab variants use a two-piece tailshaft with a centre support bearing (often listed as “Bearing Assy, Centre Support,” e.g., 37230‑0K040/0K030 supersessions). Shorter-wheelbase 4x2 Single Cab models may run a single-piece tailshaft and therefore do not have a centre-bearing. So, the centre-bearing is relevant for the majority of 2009 Hilux models, particularly long-wheelbase and 4x4 variants, while not present on some short-wheelbase 2WD models due to the shorter tailshaft design.

On 2009 Hilux models that have it, the centre-bearing supports the two-piece prop shaft mid-span, keeping everything aligned under load and over bumps. It reduces driveline vibration, helps manage the longer wheelbase, and lets the universal joints work within friendly angles so there’s less shudder on take-off and at highway speeds. The bracket and rubber insulator isolate noise and harshness from the cabin, and the sealed bearing itself is designed to be maintenance-free through normal service life.

As part of regular servicing, it’s smart to eyeball the carrier rubber and check for play every 20,000 km or whenever a vibration complaint pops up. Common clues the centre-bearing is on the way out include:

• Shudder or rumble between roughly 40–70 km/h, worse under load.
• Vibration on take-off or a “thump” on clutch engagement.
• Torn, perished, or sagging rubber in the carrier bracket.
• Metallic growl that changes with speed, not engine revs.

Replacement is straightforward for a pro and doable for a careful DIYer. Mark the driveshaft orientation before disassembly to keep phasing and balance. Support the shaft, undo the centre support bracket, separate the two sections, and press the old bearing off—don’t belt it with a hammer. Press the new bearing on in the correct orientation, refit with original alignment marks, and tighten fasteners to the workshop manual specs. While you’re there, check the uni joints and slip-yoke splines, and make sure any suspension lift or lowering hasn’t upset tailshaft angles—misalignment will chew out a fresh bearing in no time. Because the bearing is sealed, it’s a replace-not-service item
