Parts for your 2005 Toyota Bb-Universal joints

Are universal joints used on the 2005 Toyota bB?

For most 2005 Toyota bB models, universal joints (U‑joints) aren’t part of the driveline. The bB is primarily front‑wheel drive, and Toyota’s own repair literature shows the front drive shafts use constant velocity (CV) joints rather than U‑joints. Technical sources to back this up include the Toyota bB NCP30/NCP31 repair manual in Toyota’s Technical Information System (TIS), which details inboard tripod and outboard Rzeppa CV joints on the front axles with no propeller shaft on 2WD models. The Toyota Electronic Parts Catalogue (EPC) likewise lists no propeller shaft for NCP30/NCP31, while it does list a propeller shaft assembly (with U‑joints) for the NCP35 4WD variant. The 2005 Scion xB (the US‑market twin) service manual confirms the same FWD/CV‑joint layout.

Why no U‑joints on most bB models? Because in a front‑wheel‑drive setup, the gearbox and differential sit up front and drive the front hubs directly via CV shafts. CV joints handle large steering and suspension angles while maintaining constant rotational speed, giving smoother power delivery and better steering feel than a traditional U‑joint could in that role. With no rear differential or propeller shaft on 2WD cars, there’s simply nowhere a driveline U‑joint would be used.

There is one exception: the Japan‑market 4WD bB (model code NCP35) runs a propeller shaft to the rear differential, and that shaft uses U‑joints. If someone owns a 2005 bB and isn’t sure which they have, the checks below help sort it quickly.

• Model code on the build plate: NCP30/NCP31 = 2WD, NCP35 = 4WD (propeller shaft with U‑joints).
• Look underneath for a rear differential and a propeller shaft running down the centre tunnel.
• Toyota EPC/TIS lookup by VIN will show a propeller shaft only if it’s the 4WD variant.

For owners of the common 2WD bB, U‑joints aren’t a service item because they aren’t fitted in the driveline. Focus routine servicing on the front CV joints and boots: keep an eye out for split boots, grease fling inside the wheel arch, or clicking when turning at low speed. There is a small universal joint in the steering intermediate shaft on all models, if you ever feel a notch, clunk, or stiffness in the steering, that joint may need inspection or replacement. Otherwise, stick to regular CV boot checks, fresh gearbox oil at the recommended interval, and listen for any new knocks over bumps.

Popular questions about 2005 Toyota bB universal joints

Does a 2005 Toyota bB have universal joints?

Most 2WD bB models (NCP30/NCP31) don’t have driveline U‑joints because they use front CV shafts only. The 4WD NCP35 does have U‑joints on its propeller shaft. A quick look underneath for a rear diff is the giveaway.

How can someone tell if their bB needs U‑joint service?

Only the 4WD NCP35 needs U‑joint attention. Typical signs are clunks when shifting between drive and coast, vibration under load at certain speeds, or visible play at the propeller shaft joints. On 2WD cars, similar symptoms usually point to worn engine mounts, tyres, wheels, or CV joints instead.

What should be serviced instead of U‑joints on a 2WD bB?

Check CV boots every service, especially the outboard boots, and replace any split boots promptly to avoid joint wear. Listen for clicking on full lock, feel for vibration on acceleration, and keep suspension bushes and tyres in good nick. The steering intermediate shaft joint can also wear, any notchiness or a light clunk in the column is worth investigating.
