Parts for your 2013 Lexus Is-Cv joint

2013 Lexus IS CV joints — what they do and when to sort them

Based on Lexus/Toyota technical sources, a CV joint is absolutely relevant to a 2013 Lexus IS. The Lexus/Toyota Repair Manual for IS250/IS350 (GSE20/21/25) details the Rear Drive Shaft Assembly with inboard and outboard constant velocity joints and CV boot service. All-wheel drive variants also include Front Drive Shaft assemblies with CV joints. The Toyota Electronic Parts Catalogue lists Rear Drive Shaft Assemblies and separate inboard/outboard CV boots for this model year, with additional front shaft listings for AWD. Major OE/aftermarket catalogues also carry CV boots and joints for the 2013 IS. That means every rear-drive 2013 IS has CV joints at the rear half-shafts, and AWD versions add CV joints at the front as well.

On a 2013 Lexus IS, the CV joint’s job is to send power smoothly to the driven wheels while they move up and down with the suspension, and (on AWD fronts) while steering. The outboard joint is typically a fixed Rzeppa-type for smooth cornering, and the inboard joint is a plunge design to take up length changes as the suspension works. That combo keeps the drive silky while avoiding vibration and undue wear on tyres, bearings and the diff.

Day to day, the bit that needs the most love is the CV boot. It keeps the special moly grease in and the grit out. A quick look during every service (or roughly each 10,000 km) is smart: any split, loose clamp or grease fling means it’s time to act before the joint runs dry and chews itself out.

• Tell-tale signs: clicking on take-off or tight turns, a hum or vibration under load, or grease splashed around the inner rim or suspension arms.
• What to do first: if a boot’s torn but the joint’s quiet and play-free, a boot kit with fresh grease and clamps can save the day.
• When to replace the joint: if there’s clicking, visible pitting, blued races, or excess play, fit a new or quality reman joint or complete shaft.

Good practice on the IS is to use the correct high-moly CV grease, new clamps, and new circlips where specified. Torque all fasteners to the repair manual figures and use new axle nuts/bolts where Lexus calls for them. After rear shaft work, recheck diff seals for weep and road test for any driveline shudder. For AWD fronts, add a quick wheel alignment check if the strut or knuckle was disturbed.

Genuine or OE-equivalent parts tend to last the distance, especially for Aussie and Kiwi conditions with mixed city kilometres and long open-road runs. Kept clean and greased, IS CV joints typically go the distance for years without fuss.

• Does a 2013 Lexus IS have CV joints?
  Yes. All 2013 IS models have CV joints on the rear half-shafts. AWD versions also have CV joints on the front drive shafts.
• How long do CV joints last on a 2013 IS?
  With intact boots, many last well over 150,000–200,000 km. Boots are the weak link—fix a split early and the joint usually keeps going.
• Can it be driven with a torn CV boot?
  Short term only isn’t wise. Grease loss and grit ingress quickly damage the joint. It’s best to organise a boot or joint repair promptly.
