Parts for your 2002 Lexus Is-Cv boots

2002 Lexus IS CV boots — what they do, where they are, and when to sort them out

Based on technical sources including the Lexus/Toyota Repair Manual for the XE10 platform (1998–2005) and the Toyota Electronic Parts Catalogue (EPC) listings for “Rear Axle Shaft Boot Kit”, the 2002 Lexus IS (IS200/IS300, rear‑wheel drive) is fitted with constant velocity (CV) joints and rubber CV boots on each rear half‑shaft. The front end isn’t driven on this model year, so there are no front CV boots — all the CV gear lives at the back.

CV boots are flexible rubber sleeves that seal and protect the CV joints, keeping high‑moly grease in and road grit, water, and dust out. On a tidy 2002 Lexus IS, those rear boots are doing quiet, constant work every time the suspension moves and the wheels put power down. When the boots split or harden with age, grease can fling out onto the underside and the joint can run dry, which leads to clicking, shudder under acceleration, or vibration at speed.

As part of regular servicing, it’s smart to give the rear CV boots a look. A workshop following Lexus service procedures will:

• Inspect boot rubber for cracks, tears, or oil swelling, and check clamps for looseness
• Look for sling marks of dark grease around the inner guards or rear suspension
• Rotate and articulate the shaft to feel for roughness or play in the joint

If a boot is damaged but the joint’s still clean and silky, a boot‑only repair is typically fine. The proper boot kit includes new clamps and the specified CV grease, the tech will clean out the old grease, repack per kit amount, fit the boot with the correct clamp tension, and reassemble using new hardware where the manual calls for it. If the joint has run contaminated or dry, replacing the complete half‑shaft may be the better long‑term fix.

How often? Have the boots checked at every service or at least every 10,000–15,000 km, especially if the car sees plenty of rainy weather, gravel roads, or track days. Catching a small split early saves the joint. Typical repair time ranges from about 1.5 to 2.5 hours per side depending on corrosion and access, and no wheel alignment is needed for boot work on the rear half‑shafts.

Quick tip: if there’s a faint burnt‑grease smell after a drive and the rear wheels or brakes are messy with dark splatter, it’s time to book the IS in for a CV boot check.

Popular questions

Does a 2002 Lexus IS have front CV boots?
No. The 2002 IS200/IS300 is rear‑wheel drive. It uses CV joints and boots only on the rear half‑shafts. The front has steering and suspension joints but no driven CVs.

How often should CV boots be inspected or replaced on a 2002 Lexus IS?
Have them inspected at every service or roughly every 10,000–15,000 kilometres. Replace boots as soon as cracks, tears, or grease leaks show up, many original boots last well past 100,000 km if they’re kept clean and the clamps stay tight.

Is it okay to drive with a torn CV boot?
Short term, gentle trips might be possible, but it’s risky. Once grease escapes and grit gets in, the CV joint can wear quickly and start clicking or vibrating. It’s best to repair a torn boot promptly to avoid needing a full half‑shaft.
