Parts for your 2014 Subaru Forester-Universal joints

2014 Subaru Forester universal joints — what they do and how to look after them

Technical sources confirm the 2014 Subaru Forester (SJ) does use universal joints. The factory service manual for the Forester SJ (Propeller Shaft section) and the Subaru genuine parts catalogue for MY2014 identify sealed, cross-type universal joints on the propeller shaft between the transmission and rear differential. The front and rear drive shafts to the wheels use constant velocity (CV) joints instead. Subaru specifies these prop shaft U‑joints as non‑serviceable, if wear is found, the recommended repair in the service literature is replacement of the complete propeller shaft assembly.

In everyday terms, the Forester’s universal joints let the propeller shaft transmit drive to the rear diff while the shaft changes angle as the suspension moves. That flexibility keeps the all‑wheel‑drive system smooth and quiet at city speeds and out on the open road. Alongside the U‑joints, there’s a centre support bearing to steady the two‑piece shaft, all working together to keep vibration down.

Because the OEM U‑joints are sealed, there’s no regular greasing point. Instead, good servicing focuses on inspection. A workshop familiar with Subarus will check for play at the joints, rust‑coloured dust around the caps, dry or torn seals, and any notchiness when the shaft is articulated off the car. They’ll also look at the centre bearing for cracking or slop and inspect the flange bolts for security.

If a universal joint is worn, drivers often notice a driveline vibration that changes with road speed, a dull clunk when shifting from reverse to drive, or a light shudder on take‑off. Left too long, a failed joint can damage the flange yokes or centre bearing, turning a simple job into a pricier one.

Replacement paths are straightforward. Following Subaru guidance, many shops fit a complete new or remanufactured prop shaft assembly, which restores both U‑joints and the centre bearing in one hit. Some driveline specialists can press in new serviceable U‑joints to the original shaft if it’s in spec. During refit, it’s best practice to mark flange orientations, use fresh hardware or threadlocker as specified, and torque to the factory figures to avoid new vibrations.

For routine care, it’s smart to ask for a prop shaft and U‑joint check every 20,000–30,000 kilometres, or sooner if the Forester tows, sees corrugations, or has a lift kit. Catching a tired joint early keeps the AWD happy, the cabin calm, and the wallet safer.

• Common symptoms: speed‑related vibration, clunk on take‑off, chirp/squeak at low speed, visible play at the caps.
• Service tips: inspect seals and caps, check centre bearing, confirm bolt torque and flange alignment, road‑test for vibration.

Popular questions

Does a 2014 Subaru Forester have universal joints?

Yes. The 2014 Forester uses sealed U‑joints on the propeller shaft that runs to the rear differential. The wheel shafts use CV joints, so the U‑joints you’ll hear about are specifically on the prop shaft.

What are the signs a Forester’s universal joints are failing?

Typical clues include a speed‑related vibration, a clunk shifting between reverse and drive, or a chirp/squeak at low speeds that changes with vehicle speed. Underneath, you might find play at a joint or rusty dust around the bearing caps.

Can the 2014 Forester’s U‑joints be serviced, or do they need a whole new shaft?

From the factory they’re non‑serviceable and Subaru directs replacement of the complete prop shaft if a joint is worn. Some driveline specialists can rebuild the original shaft with replaceable joints if the yokes are within spec.
