Parts for your 2004 Toyota Hilux-Centre bearing

2004 Toyota Hilux centre-bearing: what it is, whether it’s there, and how to look after it

Referencing the Toyota Hilux Repair Manual (Chassis & Body, 1997–2004) and the Toyota Electronic Parts Catalogue for common 2004 model codes sold in Australia and New Zealand (e.g., LN167, KZN165, RZN169), a centre-bearing (centre support bearing) is fitted to 2004 Hilux variants that run a two-piece propeller shaft. That includes most local dual cabs, extra cabs and long‑wheelbase 4x4/4x2 models. Short‑wheelbase 2WD single cabs may use a one‑piece tailshaft and therefore won’t have a centre-bearing. For the majority of Aussie and Kiwi 2004 Hilux utes, the centre-bearing is relevant.

On vehicles where it’s fitted, the centre-bearing supports the two-piece tailshaft in the middle, keeping the shaft aligned under load and at speed. It cushions drivetrain lash with a rubber-mounted bearing, taming vibrations as the suspension moves and the engine/gearbox twist under torque. That extra support helps the Hilux handle payloads, towing and rough roads without flogging out the universal joints or hammering the gearbox and diff.

Owners can treat the centre-bearing as a regular service item to keep the driveline smooth. At routine services, a quick inspection is smart: look for cracked or perished rubber around the bearing, a sagging mount, shiny rub marks, or any free play. On the road, clues that the bearing’s on the way out include:

• Shudder on take‑off or a “boom” vibration around 40–80 km/h, especially under load
• Clunks on throttle on/off, or a buzz that changes with speed rather than engine revs
• Visible misalignment of the tailshaft at the centre mount

If replacement’s needed, it pays to use a quality bearing and bracket assembly and check associated parts at the same time. Sensible workshop practices include:

• Marking tailshaft phasing before removal to maintain balance and alignment
• Inspecting and, if needed, replacing worn universal joints alongside the bearing
• Setting correct tailshaft angles after suspension lifts or lowering kits
• Tightening fasteners to spec and rechecking for noise or vibration on a road test

Lifted Hiluxes, heavy tow rigs, and vehicles with tired engine/gearbox mounts tend to stress the centre-bearing more, so shorter inspection intervals make sense. For owners of a 2WD short‑wheelbase 2004 Hilux with a one‑piece tailshaft, there’s no centre-bearing by design—the single shaft’s length and geometry don’t require a mid‑span support, which simplifies servicing but shifts focus to the universal joints and shaft balance.

Popular questions about a 2004 Toyota Hilux centre-bearing

How can someone tell if their 2004 Hilux actually has a centre-bearing?
They can look underneath: if the tailshaft is in two sections with a support bracket roughly mid‑vehicle, that’s the centre-bearing. Many dual cabs, extra cabs and long‑wheelbase 4x4/4x2 models have it
