Parts for your 2011 Subaru Tribeca-Driveshafts

2011 Subaru Tribeca Driveshafts

Based on technical references including the Subaru Factory Service Manual for the 2011 Tribeca, Subaru’s official parts catalogue, and industry databases such as ALLDATA/Mitchell1, the 2011 Subaru Tribeca is fitted with driveshafts. It uses a two-piece propeller shaft (driveshaft) with a centre support bearing to the rear differential, plus four constant velocity (CV) axle shafts—front left/right and rear left/right—so driveshafts are absolutely relevant for this model.

The Tribeca’s Symmetrical All-Wheel Drive relies on these shafts to shift torque smoothly and reliably. The propeller shaft sends drive from the transmission to the rear diff, while the CV axles deliver power from the front and rear diffs to each wheel. CV joints at each end of the axles allow for suspension travel and, up front, steering movement, keeping everything quiet and vibration-free when they’re in good nick.

Servicing is mostly about inspection and acting early. Split CV boots are the classic early warning—once grease escapes and water/dust gets in, the joint wears quickly. A good workshop will reboot a clean, unmarked joint or replace the complete axle if there’s play, noise, or pitting. The prop shaft’s centre bearing and joints should be checked for perishing, looseness, or rust bleed at each service. Many Subaru prop shafts use non-serviceable, staked joints, if they’re worn, the shaft is generally replaced as an assembly or rebuilt by a specialist.

Typical symptoms owners might notice include clicking on full lock (outer CV wear), a shudder or vibration between 80–110 km/h (centre bearing, prop shaft phasing, or wheel/tyre), clunks on take-off (inner CV or diff mounts), or grease flung around the inner guards from a torn boot. Addressing these early saves money and avoids collateral damage.

• Inspect CV boots, clamps, and shafts every service (10,000–15,000 km).
• Check the prop shaft centre bearing, joints, and flange bolts for play and torque.
• Use quality replacement shafts, fit new axle nuts and correctly stake them.
• Mark prop shaft flanges before removal to maintain phasing and minimise vibration.
• After work, road-test and recheck fasteners once the vehicle has heat-cycled.

AWD life hack: keep tyre sizes and tread depths closely matched on all four corners, a near-new tyre paired with worn mates can stress the driveline and accelerate wear. While driveshaft work doesn’t normally affect wheel alignment, tyres should be rotated regularly and pressures kept spot on.

FAQs

Does the 2011 Subaru Tribeca have a propeller shaft as well as CV axles?
Yes. It runs a two-piece propeller shaft to the rear differential and has four CV axles—two at the front and two at the rear—because it’s full-time AWD. This setup is detailed in Subaru’s factory service information and parts listings for the 2011 model.

What symptoms suggest a worn driveshaft or CV joint on a Tribeca?
Clicking on tight turns points to an outer CV joint. A vibration or droning at highway speeds can be a tired centre bearing or prop shaft phasing issue. Clunks on take-off or gear changes may be inner CV wear or diff mount movement. Any torn boot or grease spray also needs prompt attention.

How often should driveshafts be inspected, and are the prop shaft joints serviceable?
Inspection at every routine service is sensible. Many Tribeca prop shafts use staked, non-serviceable joints, if they develop play or bind, the usual fix is replacement of the assembly or a specialist rebuild. CV axles can often be rebooted if caught early, otherwise, a quality complete shaft is the go.
