Parts for your 2002 Toyota Ist-Universal joints

2002 Toyota ist universal joints: are they used, and what’s actually relevant?

Based on Toyota’s technical literature, universal joints (U-joints) are not part of the front-wheel-drive 2002 Toyota ist driveline. The Toyota Electronic Parts Catalogue (EPC) and the NCP60/NCP61 Repair Manual show the ist’s front drive shafts using constant-velocity (CV) joints, with no propeller shaft listed for FWD variants. Toyota’s New Car Features (NCF) documentation for the NCP60 platform also describes a transverse engine/FWD layout that relies on CV joints at the front hubs and transmission, not U-joints.

Why’s that the case? CV joints deliver smooth, constant rotational speed through large steering and suspension angles — exactly what a compact FWD hatch needs. A Cardan-style universal joint, by contrast, introduces speed fluctuation at higher operating angles, which can cause vibration and wear. So for the typical 2002 ist (NCP60/NCP61), “universal joints” simply aren’t the right tool for the job, and Toyota engineers went with CV joints instead.

There are two relevant exceptions to be aware of, and both are supported by Toyota’s EPC and service references:

• 4WD variants (NCP65, available in Japan from launch) do use a propeller shaft between the front transfer and the rear differential, and that shaft is fitted with universal joints. If the vehicle is an NCP65, U-joints are absolutely relevant to servicing.
• All models have a small universal joint in the steering intermediate shaft. This is a steering component, not part of the drive axles, and it’s serviced differently from driveline U-joints.

For owners of a 2002 ist trying to figure out what they’ve got, the easiest way is to confirm the model code and hardware:

1. Check the build plate or rego details for “NCP65” (4WD) versus “NCP60/61” (FWD).
2. Look underneath: a visible propeller shaft and rear differential indicate 4WD with U-joints.
3. No prop shaft and no rear diff means FWD — no driveline U-joints, just CV joints up front.

Technical sources referenced: Toyota Electronic Parts Catalogue (EPC) for NCP60/NCP61/NCP65, Toyota Repair Manual for NCP60/61 Series, Toyota New Car Features (NCF) for the NCP60 platform. These documents outline the FWD driveline’s CV-joint configuration and identify the propeller shaft with universal joints on NCP65 4WD models.

Popular questions about 2002 Toyota ist universal joints

Does a 2002 Toyota ist have universal joints?

For most 2002 Toyota ist models (NCP60/NCP61, front-wheel drive), no — the driveline uses CV joints, not U-joints. That said, every ist does have a small universal joint in the steering intermediate shaft, but that’s a steering part, not a driveline part.

If the car is the 4WD variant (NCP65), it has a propeller shaft with universal joints between the front transfer and the rear differential, so U-joints are relevant to servicing on those models.

How can someone tell if their 2002 ist has U-joints that need servicing?

Check the model code and the underside. If it’s NCP65 and there’s a prop shaft running to a rear diff, it has driveline U-joints. Typical warning signs include clunks on take-off, vibration that changes with speed, or rust-coloured dust near the joint caps.

On FWD NCP60/NCP61 models, focus instead on CV boots and joints. Grease sling around the inner guards or clicking on full lock usually points to CV issues, not U-joints.

What should be serviced on a 2002 ist if it doesn’t use driveline U-joints?

For FWD cars, prioritise front CV boots and joints, wheel bearings, and transmission mounts. Inspect the steering intermediate shaft U-joint for play or stiffness, especially if there’s a notchy feel at the wheel.

If it’s a 4WD NCP65, add the propeller shaft U-joints and centre bearing to the list, checking for play, dryness, or binding, and ensuring the shaft is correctly phased after any work.
