Parts for your 2022 Subaru Impreza-Universal joints

2022 Subaru Impreza universal joints

Yes, universal joints are relevant and used on the 2022 Subaru Impreza in AWD form. Technical sources including the Subaru Service Manual for the 2017–2023 Impreza (Drive Shaft System section), the Subaru Electronic Parts Catalogue for MY2022 AWD models, and procedures published via Subaru’s Technical Information System identify a two-piece propeller shaft with cross-type universal joints and a centre support bearing. The halfshafts at the wheels use constant velocity (CV) joints, but the prop shaft that sends drive to the rear differential relies on universal joints.

The universal joints on the 2022 Impreza sit at each end of the propeller shaft, allowing smooth transfer of torque even as the driveline angles change with suspension movement. Their job is to keep the AWD system feeling seamless — no binding, no grumbles — while the car deals with everyday bumps, payloads and road camber. On this generation, the joints are factory-sealed, non-greasable units. That means there are no zerk fittings to service, instead, the focus is on periodic inspection and replacement if wear is found.

As part of scheduled servicing or any driveline check, a tech should:

• Inspect for free play at the U-joints, rust-coloured dust, or split seals.
• Listen and road test for tell-tales like a driveline “clunk” on take-off, a thrum or vibration that changes with speed, or a chirp under light load.
• Check the centre support bearing and mounts at the same time.
• Verify flange bolt torque and alignment marks if the shaft’s been removed, to preserve balance.

When wear is confirmed, the recommended OEM path is replacing the complete propeller shaft assembly because the universal joints are staked and not intended to be serviced separately. That said, reputable driveline specialists in Australia and New Zealand can often rebuild with quality replaceable joints if the shaft condition allows. Whichever route is chosen, use new self-locking hardware, follow the Subaru torque specs, and keep the yokes phased correctly to avoid vibrations.

For owners, a simple checklist between services helps: note any new vibration between 60–100 km/h, any clunk when shifting from reverse to drive, or a rhythmic squeak that appears at low speed and vanishes under load. Catching those early can save the rear diff mounts and keep the Impreza’s trademark surefooted feel intact.

Does the 2022 Impreza have greaseable universal joints?

No. The factory universal joints on the AWD propeller shaft are sealed, non-greasable units. Routine care is about inspection for play, noise, or leaking seals rather than adding grease. If they’re worn, replacement of the prop shaft assembly is the OEM approach.

What symptoms point to worn universal joints on this model?

Common signs include a clunk when taking off or shifting between drive and reverse, a vibration that rises with road speed, and a light squeak at low speed that often disappears under load. Any of these warrant inspection of the U-joints and centre support bearing.

Can just the U-joint be replaced, or does the whole shaft need changing?

Subaru specifies the propeller shaft as an assembly because the original joints are staked. Many driveline shops can rebuild the shaft with serviceable joints, provided the tube and yokes are sound. OEM replacement is straightforward, rebuild can be a cost-effective local option.
