Parts for your 2011 Lexus Is-Universal joints

2011 Lexus IS universal joints: what they do and how to look after them

Universal joints are relevant on the 2011 Lexus IS. Lexus/Toyota service literature (Technical Information System – TIS) for the 2011 IS 250/350 identifies universal joints in the propeller shaft assembly, and in the steering intermediate shaft. The Lexus Electronic Parts Catalogue also lists the propeller shaft assembly with staked universal joints and a centre bearing for rear-wheel-drive models, while common aftermarket manuals (e.g., Haynes/Chilton covering 2006–2013 IS) describe inspection for free play and driveline vibration tied to U-joint wear. That means the 2011 IS uses universal joints as standard driveline and steering components.

On the IS, universal joints sit at each end of the rear propeller shaft to let the shaft transmit power from the transmission to the differential even as the suspension moves. Another small uni lives in the steering intermediate shaft, allowing the column to change angle smoothly while maintaining a positive steering feel. When they’re healthy, you won’t notice them at all, when they’re tired, you’ll hear and feel them.

As part of routine servicing, it’s smart to inspect the prop shaft U-joints every 20,000–30,000 km, or any time there’s a driveline vibration complaint. Most factory Lexus joints on this model are sealed (non-greaseable) and staked into the shaft, so the usual remedy for wear is replacing the propeller shaft assembly or engaging a driveline specialist to rebuild and balance it. Aftermarket shafts or retrofit joints may be greaseable—if so, a quality NLGI 2 lithium-complex grease at service intervals helps longevity.

Tell-tale signs to watch for:

• Clunk on take-up or shifting from Drive to Reverse
• Shudder or vibration under load at certain speeds
• Squeak that changes with road speed (often at low speeds)
• Rust “bleed” at bearing caps, dryness, or any free play

If replacement’s on the cards, mark the flanges and yokes before removal to preserve phasing and balance, use new self-locking hardware where specified, and have the assembly dynamically balanced if it’s been rebuilt. After refit, a road test for vibration across speeds is a must. For the steering intermediate shaft, symptoms are notchy or self-centring steering that feels “sticky”, replacement of the shaft is the usual fix because the tiny uni is also non-serviceable. Given the driveline layout of the IS, keeping these joints in top nick preserves that smooth, quiet Lexus feel and protects the gearbox and diff from shock loads.

• Does the 2011 Lexus IS have universal joints?
  Yes. The rear propeller shaft uses universal joints, and there’s also a small uni in the steering intermediate shaft. Lexus/Toyota TIS repair procedures and the parts catalogue list these components for 2011 IS 250/350 models.
• Can the U-joints be greased on a 2011 IS?
  Factory-fitted joints are typically sealed and non-greaseable. Some aftermarket shafts or replacement joints add grease nipples, if fitted, they should be lubricated during regular servicing with a suitable chassis grease.
• What are common symptoms of a failing U-joint on this model?
  Drivers often notice a low-speed squeak, a clunk on take-up, or a vibration under acceleration. Any free play at the bearing caps or rust staining around the caps is a red flag and warrants inspection.
