Parts for your 2007 Subaru Forester-Universal joints

2007 Subaru Forester Universal Joints

Yes—universal joints are used on the 2007 Subaru Forester. Technical sources including the 2007 Subaru Forester Factory Service Manual (Propeller Shaft/Drive Line section), Subaru’s Technical Information System, and OEM parts catalogues confirm the tailshaft (propeller shaft) uses sealed universal joints with a centre support bearing. These U-joints are factory-staked and not listed as separate service parts, Subaru specifies replacement of the propeller shaft assembly if a joint is worn or seized.

On a 2007 Forester’s AWD driveline, the universal joints sit at either end of the tailshaft, allowing the shaft to transmit torque to the rear differential while accommodating suspension movement and changes in angle. They keep the driveline smooth when the car’s loaded, cresting a hill, or powering out of a bend. While the front and rear half-shafts use constant velocity (CV) joints for steering and suspension travel, the tailshaft relies on U-joints for compact, durable articulation at consistent rotational speeds.

Because the factory U-joints are sealed and don’t have grease nipples, maintenance is all about periodic inspection. During routine servicing, it’s smart to check for tell-tale signs: reddish dust around a cap (fretting), cracked end seals, play in the joint when the tailshaft is twisted by hand with the vehicle safely supported, and any notchiness when the shaft is articulated. On the road, symptoms of a failing U-joint include a clunk on take-off or shifting from reverse to drive, a shudder under load at low speeds, and a vibration that doesn’t change with engine rpm but does with vehicle speed. If any of these crop up, sort it promptly to protect the centre bearing and rear diff.

When replacement time comes, owners typically choose one of two routes. The OEM path is a complete tailshaft assembly swap, which restores factory balance and is quick to fit. The specialist route is a driveline shop rebuild, where the staked joints are machined out and replaced with high-quality circlip-style U-joints, then the shaft is rebalanced—often a cost-effective, perfectly reliable fix. Either way, use new flange bolts, align paint marks to preserve phasing, and torque to spec. A fresh tailshaft with tight U-joints makes the Forester feel taut and tidy again.

• Inspection tip: check U-joints and centre bearing every 10,000–15,000 km or at each service.
• Driving tip: avoid harsh clutch dumps or towing beyond rating to reduce shock loads on the joints.

Popular questions about 2007 Subaru Forester universal joints

Does a 2007 Subaru Forester have universal joints or only CV joints?
It has both. The front and rear drive axles use CV joints, while the tailshaft running to the rear differential uses two universal joints. That’s straight from the Forester service manual’s Propeller Shaft section and is reflected in OEM parts listings that show a complete shaft assembly.

How long do the universal joints typically last?
Service life varies with use, but many see 150,000–250,000 km. Regular towing, rough roads, or boot/seal damage can shorten that. Listen for clunks and feel for shudders, early diagnosis prevents collateral wear on the centre support bearing and diff mounts.

Can the U-joints be greased or replaced individually?
From the factory they’re sealed and not greaseable, and Subaru doesn’t list them as separate parts. You can either replace the complete tailshaft or have a driveline specialist rebuild it with replaceable circlip-style U-joints and then balance the assembly—both are proven approaches.
