Parts for your 2006 Lexus Is-Cv joint

2006 Lexus IS CV Joint — What It Does and How to Look After It

Technical sources confirm the 2006 Lexus IS does use CV joints. The Lexus/Toyota Repair Manual (GSE20/21/25, Drivetrain/Axle sections for Rear Drive Shaft and, on AWD, Front Drive Shaft) describes inboard and outboard constant velocity joints on each driven half‑shaft. The Lexus Electronic Parts Catalogue likewise lists complete rear drive shaft assemblies with CV joints for RWD models, and front drive shafts with CV joints for AWD. Put simply: every 2006 IS has CV joints on the rear, AWD variants have them front and rear.

On this generation IS, the CV joint’s job is to transfer torque smoothly through the suspension’s full range of motion, keeping things quiet and vibration‑free while the wheels move up and down. RWD cars run a pair of rear half‑shafts with inner tripod (or DOJ) and outer Rzeppa‑type joints. AWD models add the same arrangement up front. When the joints and boots are healthy, the car feels tight, refined and drama‑free — exactly how a Lexus should.

As part of regular servicing, it pays to eyeball the CV boots and surrounding areas. A quick look on a hoist for split rubber, slung grease around the inner guard, or loose clamps can save a pricey shaft later. Boots are the first line of defence, once they tear and water or grit gets in, the joint can wear rapidly.

• Common symptoms owners notice:
  • Grease spray near the wheel or diff and damp, perished boots
  • Clicking on acceleration or tight turns (front, AWD), or a thud on take‑off (rear, RWD)
  • Vibration under load at motorway speeds
• Service tips that work in Aus/NZ conditions:
  • Inspect boots every service or 10,000–15,000 km, especially after gravel roads or coastal use
  • If a boot has just torn and the joint is quiet, a reboot kit with fresh high‑moly grease can be fine
  • If there’s noise, play, blueing, or pitting, replace the complete shaft for reliability and time savings
  • Always renew hub nuts and boot clamps, torque to spec, and road test for noise and vibration

Whether it’s an IS250/350 RWD or an AWD variant, keeping the CV boots tidy and the grease where it belongs will keep the driveline smooth and the tyres wearing evenly.

Does a 2006 Lexus IS have CV joints?
Yes. RWD models use CV joints on the rear half‑shafts. AWD models have CV joints on both front and rear axles, as outlined in the Lexus/Toyota Repair Manual and parts catalogue.

What are the signs the CV joints need attention?
Look for split boots and grease fling, clicking on acceleration or when turning (front on AWD), clunks on take‑off (rear), and vibration under load. Any of these means it’s time for inspection.

Should the boots be replaced or the whole shaft?
If the boot has just failed and the joint is still quiet with no play, a reboot is usually fine. If there’s noise, corrosion or wear, a complete shaft replacement is the reliable fix and often saves labour.
