Parts for your 2020 Toyota Vitz|yaris-Universal joints

Are universal joints used on the 2020 Toyota Vitz/Yaris?

Technical sources from Toyota service information and the 2020 Yaris/Vitz New Car Features material indicate the model uses constant-velocity (CV) joints on the front drive shafts rather than cross-type universal joints. The factory repair procedures for the front drive shaft assemblies detail outboard Rzeppa CV joints and inboard tripod/plunge CV joints, with no propeller shaft on front‑wheel‑drive variants. Where available, hybrid AWD-i versions drive the rear wheels via an electric motor at the axle, so there’s still no prop shaft or driveline U-joints. The only universal joints on the vehicle are typically in the steering intermediate shaft, not in the driveline.

Why aren’t universal joints used on the 2020 Vitz/Yaris driveline? CV joints maintain constant rotational speed through large operating angles, which is essential for a FWD hatch that steers and suspends through big arcs at the front hubs. A single Cardan (universal) joint creates speed fluctuation at angle, which would cause vibration, torque ripple and premature wear. Packaging and NVH targets in this segment also favour Rzeppa and tripod CV joints. These principles are well-established in OEM literature and standard references like the Bosch Automotive Handbook and SAE texts covering FWD half-shaft design.

For owners asking about “universal joint replacement” on this model, the relevant service focus is the CV joints and boots, and the steering column U-joint. The CV boots should be inspected every service for splits, grease sling around the inner guard or wheel, and any clicking on full lock — classic signs of an outer CV on the way out. The inner tripod joint may present as vibration under load. If a boot is torn, acting early with a boot kit can save the joint, once contaminated, a full shaft or joint replacement is usually the go. Use quality grease and clamps to factory spec, and follow the torque specs in the Toyota service manual when refitting axle nuts and hub fasteners.

The steering intermediate shaft U-joint isn’t a routine replacement item but should be checked for stiffness, rust binding, or free play if there’s a notchiness or clunk through the wheel. Any binding is a safety concern, replacement of the intermediate shaft is the proper fix rather than a temporary lube. A road test after work, plus a quick check of wheel alignment if suspension arms were disturbed, keeps everything tidy and safe for the kilometres ahead.

• Symptoms to watch: clicking on turns, vibration under load, grease spray near a front wheel, notchy steering or clunks.
• Service tip: keep CV boots intact, once water gets in, the joint won’t last long.

Popular questions about 2020 Toyota Vitz/Yaris universal joints

Does a 2020 Toyota Vitz/Yaris have universal joints in the driveline?

No. The driveline uses CV joints on the front half-shafts. Toyota service information for the 2020 model explains the use of Rzeppa (outer) and tripod (inner) CV joints. Only the steering intermediate shaft typically has a small U-joint. Hybrid AWD-i variants use an electric rear axle, so there’s no prop shaft U-joint either.

What should be serviced instead of driveline U-joints on this model?

Focus on the front CV joints and boots. At each service, check for split boots, grease leaks, and clicking on full lock. If a boot is damaged, replace it promptly, if the joint’s noisy or rough, replace the joint or complete shaft. Also check the steering column U-joint for stiffness or play if steering feels notchy.

How can someone tell if the steering U-joint is worn on a Yaris/Vitz?

Common signs are a notchy feel, a tight spot as the wheel is turned, or a small clunk over bumps. Visual inspection can reveal rust or binding at the joint. Lubricants might mask symptoms briefly, but replacement of the intermediate shaft is the correct repair for safety and roadworthiness.
