2003 Toyota Altezza CV Joint — what it does and how to look after it

Yes, a CV joint is relevant to the 2003 Toyota Altezza. Being rear‑wheel drive on the XE10 platform, it uses constant velocity joints on the rear drive shafts (half‑shafts) from the differential to each rear hub. Factory references that confirm this include the Toyota/Lexus repair manual for the XE10 (Rear Drive Shaft section, often catalogued as RM series) and the Toyota Electronic Parts Catalogue for GXE10/SXE10, which lists rear drive shaft assemblies with inboard and outboard joints and corresponding boot kits. The front of the Altezza doesn’t use CV joints because it isn’t front‑wheel drive.

On this car, the CV joints allow smooth transfer of torque to the rear wheels while the suspension moves up and down and the wheels travel through their arc. They keep driveline vibration low, stop binding at sharper angles, and help maintain quiet, predictable acceleration. Each joint is packed with high‑moly grease and sealed by a rubber boot, once that boot splits, the grease escapes, grit gets in, and the joint can wear quickly.

As part of regular servicing, it’s smart to check both rear CV boots for cracks, splits, or grease spray every 10,000–15,000 km, or sooner if the car is lowered, used on rough roads, or sees track work. If a boot is torn but the joint isn’t noisy, a timely boot-and-grease refresh can save the joint. If there’s clicking on take‑off, shudder under load, or a rhythmic knock on acceleration, plan for joint or complete shaft replacement.

• Listen for clicking/knocking on acceleration or low‑speed turns.
• Look for grease flung around the inner guard, subframe, or rear hub.
• Feel for driveline vibration that rises with road speed.

When replacing, many workshops fit a complete rear drive shaft for reliability and time savings, quality joint or boot kits are also viable if the wear is minimal. Use the specified molybdenum disulphide CV grease, new clamps, and new axle/hub nut where required. Torque fasteners to the service manual values, and avoid levering against the diff seals when removing the inboard end. After refit, check diff oil level, and if any suspension arms were loosened, have the rear alignment checked. With intact boots and the right grease, Altezza CV joints typically run for very high kilometres without drama.

Popular questions

Does a 2003 Toyota Altezza have CV joints?
Yes. The rear drive shafts use CV joints at the inboard and outboard ends. Front wheels don’t have CVs because the Altezza is rear‑wheel drive. This layout is documented in the Toyota/Lexus XE10 repair manual and the Toyota EPC listings for GXE10/SXE10 rear drive shafts and boot kits.

How long do Altezza CV joints or boots last?
If the boots stay intact and the correct grease is used, the joints can last well over 150,000 km. Boots are rubber and age with heat and road grime, so inspect them at each service and replace at the first sign of cracking or grease seepage to prevent joint damage.

Do you have to replace the whole shaft, or just the CV joint?
Both options are common. A full shaft assembly is quick and often cost‑effective. If the joint isn’t worn and only the boot has failed, a boot kit and re‑grease is fine. Follow the service manual for torque specs and handling to avoid damaging diff seals or wheel bearings.
