Parts for your 2005 Lexus Is-Universal joints

2005 Lexus IS universal joints — what they do and how to look after them

Yes, universal joints are used on the 2005 Lexus IS. Factory repair literature for the IS200/IS300 (Toyota/Lexus TIS workshop manual, Propeller Shaft and Steering sections) specifies universal joints in the rear propeller shaft and in the steering intermediate shaft, and the Lexus parts catalogue lists the intermediate shaft assembly with a built‑in U‑joint. On most models of this era, the propeller shaft U‑joints are the staked, non‑serviceable type.

On the driveline, the universal joints allow the two‑piece propeller shaft to transmit engine torque to the differential while coping with suspension movement and the slight angles between gearbox and diff. In the steering column, a compact U‑joint links the column to the rack, letting the shaft articulate without binding. When these joints are healthy, the car feels smooth and tight, when they wear, owners notice vibrations, clunks and vague steering.

Servicing is mainly inspection, because the IS’s OE U‑joints are sealed and typically not greaseable. During routine services (or any time the shaft is out), a tech should check for free play, roughness, rust “dust” around the caps, perished seals and any sign of binding. It’s smart to also look at the centre support bearing and the prop shaft phasing marks. Catching wear early prevents collateral damage to the diff, gearbox mount or tyres from driveline vibration.

If replacement is needed, Lexus procedure usually calls for swapping the complete propeller shaft assembly due to the staked joints. Many driveline specialists in Australia and New Zealand can machine out the staked spiders, fit serviceable U‑joints and rebalance the shaft — a solid option for long‑term ownership. The steering intermediate shaft U‑joint is replaced as an assembly, correct alignment of the splines and steering wheel centring is important. After any work, road‑test for shudder on take‑off and vibration around 60–100 km/h.

• Common symptoms: a thud when shifting from reverse to drive, a chirp or squeak at low speed, and a buzz or shudder under load.
• Inspection tip: with the car safely raised, hold the yoke and try to rotate the shaft in both directions, any noticeable play or notchiness points to a worn joint.
• Service rhythm: eyeball at every service, thorough check every 40,000–60,000 kilometres or before big trips.

Popular questions about 2005 Lexus IS universal joints

Does a 2005 Lexus IS have universal joints, and where are they?
It does. There are U‑joints in the rear propeller shaft, and a compact universal joint in the steering intermediate shaft. The rear joints manage driveline angles, the steering joint lets the column articulate smoothly.

Can the original U‑joints be greased or replaced individually?
From factory they’re sealed and generally not greaseable. The prop shaft joints are staked in, so Lexus specifies replacing the complete shaft. A driveline specialist can often retrofit serviceable U‑joints and then balance the shaft, which is a popular local solution.

What are the signs the U‑joints are worn on an IS?
Tell‑tales include a clunk when taking off or changing from reverse to drive, a chirp at low speeds, and vibration between 60–100 km/h. On inspection you might see rust powder at the caps or feel notchy movement. If any of these show up, get it checked promptly.
