Parts for your 2017 Lexus Is-Cv joint

2017 Lexus IS CV joint: purpose, fitment and servicing tips

CV joints are absolutely relevant to a 2017 Lexus IS. Lexus service documentation for the XE30 series (Drivetrain/Axle – Rear Drive Shaft, Lexus Repair Manual) and Toyota’s Electronic Parts Catalogue list rear drive shafts with inner and outer CV joints and boots for RWD models (e.g., GSE31 IS 350, ASE30/AVE30 IS 200t/IS 300h). In markets where AWD was offered, the IS also has front CV axles. For Australia and New Zealand, the 2017 IS range was typically rear‑wheel drive, so the CV joints live on the rear drive shafts, not the front.

On a 2017 Lexus IS, the CV joint’s job is to transmit power smoothly from the differential to the rear wheels while the suspension moves up and down. The design lets the shaft change angle without binding or pulsing, keeping the ride refined and the power delivery tidy. Each rear shaft has an inner joint (usually a tripod-style for plunge) and an outer joint (typically a Rzeppa-type for articulation), both packed with specialised moly grease and sealed by rubber boots noted in Toyota parts catalogues as boot kits with clamps and grease.

As part of regular servicing, it’s smart to inspect those rear CV boots every service or 10,000–15,000 km. If a boot cracks or splits, grease escapes and road grit gets in, quickly wearing the joint. Catch a torn boot early and a boot kit and grease repack usually sorts it. Leave it too long and the joint may click, clunk on take‑off, or cause a vibration under load, in which case replacing the joint or complete shaft assembly is the go. Genuine or quality aftermarket shafts both work, the workshop manual outlines procedures, including using a new axle nut and snap ring and torquing fasteners to spec.

• Listen for clicking or knocking under acceleration, and feel for vibrations that rise with speed.
• Check boots for splits, grease fling around the inner guard, or perished rubber.
• If replacing a boot, clean thoroughly and use the correct CV grease, for noisy joints, opt for a full shaft or joint replacement.
• After work, road test for noise and recheck for grease leaks.

Popular questions

Does a 2017 Lexus IS have front CV joints?
RWD Australian and New Zealand models don’t have front CV axles, so no front CV joints. AWD variants sold in some regions do have front CV joints as well as rears.

What are the signs the rear CV joints are failing?
Common signs include clicking or knocking when accelerating, a shudder or vibration under load, and visible grease spray from a split boot. If noise is present, the joint or entire shaft usually needs replacement.

Should the boot be replaced or the whole shaft?
If the boot’s torn but the joint’s still quiet and free of play, a boot kit and repack is fine. If there’s clicking, roughness, or metal contamination, replacing the complete shaft or joint is the better long‑term fix.
