2017 Lexus IS CV Boots — What They Do and When to Replace

CV boots are absolutely relevant on the 2017 Lexus IS. Referencing the Lexus/Toyota Electronic Parts Catalog (EPC) and the Lexus Technical Information System (TIS) service procedures for the 2017 IS range (GSE3#/ASE3#/AVE3#), this model uses rubber CV boots to protect the constant velocity joints. Rear-wheel drive variants have CV boots on the rear axle shafts, while all-wheel drive variants are fitted with CV boots on both the front and rear drive shafts. In the EPC these appear as “Boot Kit, Front Drive Shaft” and “Boot Kit, Rear Drive Shaft,” and TIS outlines inspection and replacement steps during driveline service.

On a 2017 Lexus IS, the CV boots keep special grease inside the CV joints and keep water, dust and road grit out. That sealed environment lets the joints articulate smoothly as the suspension moves and the wheels turn, without wearing prematurely. Whether it’s an IS 200t/300 (2.0T), IS 300 AWD, or IS 350 (RWD/AWD), healthy CV boots are key to quiet, smooth driveline operation and long CV joint life.

As part of servicing of your 2017-lexus-is cv-boots, it pays to add a regular visual check. A small split or perished rubber can quickly fling grease onto underbody panels and brakes, inviting grit into the joint. If a boot is torn, the smart move is to replace the boot, flush and re-grease the joint, and fit new clamps before the joint starts clicking under load. If noise or play is already present, the safer repair is a complete shaft or joint replacement. Most owners have the boots inspected at each service interval and especially after long gravel-road trips or kerb strikes.

• Look for grease spray on the inside of the wheels or underbody — a classic sign of a split boot.
• Check clamps for looseness and the boot for cracks, hardening, or swelling.
• Avoid harsh solvents when cleaning, they can dry and crack the rubber.
• If a boot is compromised, don’t delay — prompt boot replacement can save the CV joint.
• For AWD IS models, remember there are front and rear boots to inspect.

Popular questions about 2017 Lexus IS CV boots

Do RWD 2017 Lexus IS models have CV boots?
Yes. Even the rear-wheel drive versions use CV boots on the rear half-shafts. Independent rear suspension requires CV joints at the differential and the wheel hubs, and those joints are protected by rubber boots. AWD models add CV boots to the front drive shafts as well.

How can someone tell a CV boot is failing on a 2017 Lexus IS?
Common clues include grease flung around the inside of the wheel or along the underbody, a visible split or crack in the boot, or loose/damaged clamps. If the joint has already ingested grit, there may be a clicking noise on acceleration or when turning (AWD). Catching a torn boot early usually prevents joint damage.

Can a torn CV boot be replaced without changing the whole axle?
Often, yes. If the joint is still quiet and free of play, a boot kit with new grease and clamps is a sensible fix. If the joint is noisy or feels rough, it’s more cost-effective to replace the complete shaft or joint assembly to restore reliability.
