Parts for your 2005 Toyota Ractis-Universal joints

2005 Toyota Ractis universal joints — what’s actually fitted and what to service

Technical sources checked: Toyota Ractis Repair Manual (P1, NCP100/NCP105, Drivetrain/Axle), Toyota Electronic Parts Catalogue (EPC) for NCP100 and NCP105, and Toyota New Car Features for the B‑platform AWD layout. These show that the 2005 Ractis in 2WD form (model code NCP100/SCP100) uses front drive shafts with constant velocity (CV) joints and has no propeller shaft, so no driveline universal joints. The 4WD variant (model code NCP105) adds a propeller shaft to the rear differential, which uses universal joints.

So, for most 2WD Ractis seen across Australia and New Zealand, a driveline universal joint isn’t relevant — the car relies on CV joints at the front hubs and inner shafts. On 4WD Ractis (look for model code NCP105 or a 4WD badge), universal joints are fitted on the propeller shaft and do need periodic attention.

If the vehicle is the 4WD model, universal joints (U‑joints) are what let the propeller shaft transfer torque to the rear diff while the shaft changes angle with suspension and body movement. They keep the driveline smooth under load and through bumps. When they wear, the tell‑tales are clunks on take‑off, a shudder or vibration that tracks vehicle speed (often 40–80 km/h), a squeak that speeds up with road speed, red/brown dust around the bearing caps, or any free play you can feel at the yokes with the shaft supported.

Servicing on a 4WD Ractis is straightforward: during regular services (say every 10,000–15,000 km), inspect the prop shaft for play, dry seals, rust staining and missing circlips. Many OE Toyota U‑joints are sealed-for-life, if yours has no grease nipples, you don’t grease it — you replace it when worn. Some aftermarket joints do have nipples, a couple of pumps of quality lithium complex or high‑moly grease at service time is plenty. Avoid over‑greasing and always wipe excess.

Replacement tips a good workshop will follow include: mark the flanges so the shaft goes back in phase and in the same orientation, support the shaft to protect the centre bearing, and never mix bearing caps. Press joints out with proper tools (don’t belt them with a hammer), fit new circlips, and torque the flange bolts to the repair manual spec. If there’s any persistent vibration after the job, have the shaft checked for balance. While you’re under there, give the centre bearing and rear diff flange a once‑over — it’s cheap insurance.

If yours is a 2WD Ractis, don’t stress about U‑joints — they’re simply not part of the driveline. Focus your attention on front CV boots and joints instead, as those are the key wear items on 2WD cars.

• How to tell which you have: check the model code (NCP100 = 2WD, NCP105 = 4WD) or look underneath for a propeller shaft running to the rear diff.

FAQs

Does my 2005 Ractis have universal joints?
Most 2WD Ractis (NCP100/SCP100) don’t have driveline U‑joints — they use CV joints up front only. The 4WD Ractis (NCP105) has a propeller shaft with U‑joints to drive the rear wheels. A quick look underneath for a rear diff and prop shaft, or checking the model code, will tell you which you’ve got.

What are the signs a Ractis U‑joint is failing?
On 4WD cars, look for a clunk when shifting from reverse to drive, vibration that follows road speed, or a chirp/squeak that rises with speed. Red/brown dust around the bearing caps or any play at the yokes are also red flags.

Can Ractis U‑joints be greased?
Many factory Toyota U‑joints are sealed and non‑greasable. If your replacement joints have grease nipples, give them a light grease at each service. If they’re sealed and worn, replacement is the go.
