Parts for your 2017 Subaru Forester-Universal joints

2017 Subaru Forester universal joints

Universal joints are absolutely used on the 2017 Subaru Forester. Technical sources back this up: the Subaru SJ Forester Service Manual (Propeller Shaft section, 2014–2018) specifies a two‑piece propeller shaft with a centre support bearing and universal joints, and notes the joints are non‑disassemblable and serviced with the shaft assembly. The Subaru parts catalogue for MY2017 Forester lists propeller shaft assemblies (for example, 27111SG0xx family) and does not list individual U‑joints as service parts. That means universal joints are relevant to driveline servicing on this model.

On this Forester, the propeller shaft links the transmission’s transfer output to the rear differential, and the universal joints let that shaft articulate as the suspension works and the drivetrain moves under load. Without U‑joints, the shaft would bind, causing vibration and damage. Subaru fits sealed, non‑greaseable joints from factory, prioritising low maintenance and durability.

Because the OEM joints are sealed, there’s no routine greasing point. Maintenance is about inspection and early detection. At regular services (say every 30,000–50,000 km, or sooner if the vehicle tows, sees beach work, or has a lift), a technician should:

• Check for play at the prop shaft flanges and in the centre support bearing.
• Spin and feel for roughness, notching, or tight spots.
• Look for rust dust around bearing caps, torn dust seals, or slung grease streaks.
• Road test for shudder on take‑off, a chirp/squeak at low speed, or a vibration that peaks around 60–100 km/h under load.

If the U‑joint is worn, Subaru’s guidance is to replace the propeller shaft assembly as a unit. That preserves factory balance and reliability. A quality aftermarket shaft is a sound option. Some driveline specialists can rebuild the original shaft with serviceable U‑joints, that can be cost‑effective, but it must be properly balanced and the centre bearing assessed at the same time.

Replacement tips a workshop will follow:

• Mark flange orientations before removal to maintain phasing and minimise vibration.
• Torque fasteners to Subaru specs and use new flange bolts if they’re stretched or corroded.
• Inspect the rear diff and transfer output seals, renew if weeping while the shaft is out.
• After fitment, road test for any new vibration, then recheck fasteners after a short run.

Look after the U‑joints with sensible checks, and this Forester’s AWD driveline will stay smooth and quiet for the long haul.

Popular questions about 2017 Subaru Forester universal joints

Do 2017 Forester U‑joints need greasing?
No. The factory universal joints are sealed and not greaseable. They’re designed to run for a long time without attention. If one develops play or noise, the usual fix is to replace the propeller shaft assembly, or have a driveline specialist rebuild it with serviceable joints and then re‑balance it.

What are the common signs a U‑joint is failing on this model?
Drivers often notice a chirp or squeak at low speeds that changes with road speed, a clunk when selecting Drive or Reverse, or a vibration under load around highway speeds. Under the vehicle, rust powder at a bearing cap or noticeable play at a flange are red flags.

How much does replacement usually cost in AU/NZ?
Ballpark, a new OEM‑style propeller shaft assembly typically lands around AUD/NZD $1,100–$1,800 for the part, plus roughly 1–2 hours’ labour. A quality aftermarket or specialist rebuild can be cheaper (often AUD/NZD $500–$900), provided the shaft is correctly balanced and the centre bearing is healthy or replaced.
