Parts for your 2012 Toyota Wish-Universal joints

2012 Toyota Wish universaljoints — are they actually used?

For most 2012 Toyota Wish models, universal joints (universaljoints) aren’t part of the driveline. The front-wheel-drive ZGE20/21 series uses constant velocity (CV) joints on the front drive shafts, not U-joints. This is supported by Toyota’s Electronic Parts Catalog for the ZGE20/21 range and the Drivetrain/Axle sections of the Toyota Repair Manual, which list inboard/outboard CV joints for the front axles and no propeller shaft or cardan U-joints on FF models.

Why no universaljoints on a 2012toyotawish? A front-drive transaxle needs joints that keep rotational speed steady while the wheels steer and move through suspension travel. A single cardan U-joint varies shaft speed across an angle, which can cause vibration and shudder. CV joints, on the other hand, maintain constant angular velocity at large steering angles and are quieter, smoother, and better packaged for a compact MPV like the Wish. That’s why Toyota engineers specified CV joints up front and, on FF models, omitted any propeller shaft entirely—so there’s simply no place a traditional U-joint would live.

There is one wrinkle: certain Japanese domestic market 4WD variants (model code ZGE25) exist. Those have a propeller shaft running to the rear. Per Toyota service information, that shaft is serviced as an assembly and the joints are typically non-serviceable at dealer level. Even then, routine “universaljoints” greasing or replacement isn’t a standard maintenance item on a 2012toyotawish, inspection focuses on the prop shaft assembly, centre bearing, and seals.

If you’re chasing noises or vibration on a 2012 Toyota Wish and you’re thinking universaljoints, it’s worth refocusing on what’s actually fitted:

• Front CV joints and boots: look for split boots, fling of grease, clicking on turns.
• Front wheel bearings and tyres: humming that rises with speed can mimic driveline issues.
• For 4WD only: check the propeller shaft assembly for play at the centre bearing and any clunks on take-up, replace the assembly if out of spec per the repair manual.

Bottom line for 2012toyotawish universaljoints: on front-drive models they’re not used, and on 4WD variants they’re not a routine service item. Focus maintenance on CV joints, boots, and associated hardware for the best result.

Does a 2012 Toyota Wish have universaljoints from factory?

Front-wheel-drive models don’t. They use CV joints on the front axles and have no prop shaft. Some 4WD variants have a propeller shaft, its joints are typically non-serviceable at dealer level and the shaft is replaced as an assembly if worn.

How can someone tell if their 2012toyotawish is 4WD and might have a prop shaft?

Check the build plate/model code (ZGE25 usually indicates 4WD), look underneath for a propeller shaft running to a rear differential, and confirm the rear subframe has a diff housing. If it’s FF (ZGE20/21), there’ll be no prop shaft.

What should be serviced instead of universaljoints on a 2012 Toyota Wish?

Inspect CV boots every service, replace any torn boots promptly, and listen for clicking on full lock (outer CV) or shudder on take-off (inner CV). Also check wheel bearings, alignment, and tyre condition for NVH that can mimic driveline faults.
