2013 Lexus IS CV boots: what they do and how to look after them

Yes, CV boots are relevant to the 2013 Lexus IS. The Toyota/Lexus TIS workshop manual for the GSE2# series (Drivetrain/Axle section) details front drive shafts with CV boots on AWD models and rear half‑shafts with CV boots on all models with independent rear suspension. The Toyota Electronic Parts Catalogue (EPC) and Lexus dealer parts catalogues likewise list inner and outer CV boot kits for the rear on RWD IS250/IS350 (GSE20/GSE21) and for both front and rear on AWD variants (GSE25/GSE35). Major aftermarket catalogues also carry boot kits for these applications.

On a 2013 Lexus IS, the CV boots are the flexible rubber bellows that seal grease around the constant velocity joints on the drive shafts. They keep water and grit out and high‑moly grease in, so the joints stay quiet and smooth when the suspension moves and, on AWD cars, when the front wheels steer. If a boot splits, grease flings out, contaminants get in and the joint can wear quickly—turning a simple boot job into a pricier shaft or joint replacement.

As part of routine servicing, it’s smart to have the CV boots inspected from underneath and behind the wheels. Look for damp, flung grease on the inner rims, control arms or under‑trays, and any cracks in the rubber, especially near the small and large ends of the bellows. In Australia and New Zealand, a quick look every service interval (10,000–15,000 km) is cheap insurance, particularly if the car sees gravel roads, coastal air or hot summers that age rubber faster.

If a boot is torn but the joint is still quiet, a proper boot replacement with new clamps and the correct specification moly CV grease can save the original shaft. Techs will remove the driveshaft, clean the joint, re‑pack with grease and fit a quality OEM‑style boot—avoiding cable ties and off‑brand clamps that can leak. If there’s clicking on turns (front AWD) or shudder under load, the joint may already be worn, at that point, a complete shaft may be the most reliable fix.

RWD IS models have CV boots on the rear only, AWD models have them front and rear. Either way, keeping the boots intact means quieter driveline operation, less vibration and fewer surprises at WOF/rego time.

• Watch for grease spray on wheels or underbody
• Replace boots at first sign of cracking or splits
• Use proper clamps and the right high‑moly CV grease

FAQs

Does a 2013 Lexus IS have CV boots?
Yes. All RWD models have CV boots on the rear half‑shafts. AWD models have CV boots on both the front and rear drive shafts.

How often should CV boots be checked on a 2013 IS?
Have them inspected at every service. In local conditions, that’s typically every 10,000–15,000 km. Replace a boot as soon as it’s cracked or leaking to avoid joint damage.

Can a split CV boot be a temporary fix with tape or a “quick boot”?
Temporary fixes rarely last. The reliable approach is removing the shaft, cleaning and re‑greasing the joint, and installing an OEM‑style boot with proper clamps. If the joint is already noisy, consider replacing the shaft.
