Parts for your 2010 Subaru Forester-Driveshafts

2010 Subaru Forester driveshafts — what they do and how to look after them

Driveshafts are absolutely relevant on the 2010 Subaru Forester (SH). Technical sources including the Subaru Factory Service Manual (FSM) for the SH-chassis Forester (Driveline/Axle and Propeller Shaft sections) and the Subaru FAST parts catalogue list front left/right drive shafts (CV axles) and a two‑piece propeller shaft running to the rear differential. That layout is core to Subaru’s Symmetrical AWD system used across 2010 Forester variants.

On this Forester, the front CV driveshafts transfer torque from the transaxle to the front hubs while allowing steering angle and suspension travel. Out back, a two‑piece propeller shaft with a centre support bearing sends drive to the rear diff. Together, they keep the AWD dependable on wet tarmac, gravel, and the odd farm track.

As part of routine servicing, it pays to give the driveline a once‑over. Forester owners should have the CV boots checked every service interval for splits, loose clamps, or flung grease. Catching a torn boot early and re‑booting can save a perfectly good joint. If a joint clicks on full lock or feels notchy, replacing the complete CV shaft assembly is usually the smart move.

The prop shaft deserves attention too. Look for vibration under load or at highway speeds, a thump on take‑off, or a droning noise — all can point to a tired centre support bearing or worn universal joints. Many Subaru prop‑shaft U‑joints are staked and not designed for field service, replacement of the assembly or specialist refurbishment is common practice.

During any axle work, match parts by VIN to get the right shaft length and spline count, keep the inner CV supported so it doesn’t stress the transaxle seals, and always tighten the axle nut and flange bolts to the FSM torque specs. Refit any balance marks on the prop shaft exactly as found to avoid introducing vibration. Quality parts matter here — genuine or reputable aftermarket shafts and boots will last longer, especially in Aussie and Kiwi conditions with heat, corrugations, and coastal salt.

Typical warning signs owners notice include:

• Clicking on turns, shudder on acceleration, or grease sprayed inside a front wheel
• Vibration at 80–100 km/h, clunks on take‑off, or a humming/droning from beneath the car

Sort issues early and the Forester’s driveline will keep delivering that planted, sure‑footed AWD feel for many kilometres.

Does a 2010 Forester have a rear driveshaft?

Yes. All 2010 Subaru Forester AWD models use a two‑piece propeller shaft with a centre support bearing to drive the rear differential. It’s a key part of Subaru’s Symmetrical AWD layout.

How long do the CV shafts and prop shaft usually last?

With intact boots and normal use, CV shafts can run well past 150,000 km. The prop shaft often lasts even longer. Harsh roads, lifted suspensions, or damaged boots can shorten that lifespan, so regular inspection is worthwhile.

Is it safe to keep driving with a noisy CV or vibrating prop shaft?

Not recommended. A failing CV joint can let go and leave the vehicle without drive, a vibrating prop shaft can damage bearings and seals. It’s best to inspect and repair before it escalates.
