Parts for your 2016 Subaru Exiga-Universal joints

2016 Subaru Exiga universal joints — what they do and how to look after them

Based on Subaru’s factory service documentation for the Exiga/Crossover 7 (Propeller Shaft section), Subaru technical explanations of Symmetrical AWD driveline layout, and Subaru parts catalogue listings that include propeller shaft universal joints for YA-series Exiga models, the 2016 Subaru Exiga (sold as the Crossover 7 in many markets) uses universal joints on its tailshaft. Front axles use constant-velocity (CV) joints, while the tailshaft uses cardan-type universal joints to transmit drive to the rear differential.

On the Exiga, the universal joints sit at the ends of the tailshaft, allowing the shaft to rotate smoothly as the suspension moves and the angles between the transmission and rear diff change. That flexibility is what stops binding, vibration and premature wear in the AWD driveline. Unlike the CV joints at the wheels, these tailshaft U-joints primarily handle angular misalignment rather than large steering angles.

Most late-model Subaru tailshaft U-joints are sealed and not designed for periodic greasing. Many are staked into the shaft from factory, so Subaru’s service literature often specifies replacing the complete tailshaft if a joint fails, or having a driveline specialist rebuild and balance the shaft. There isn’t a set replacement interval, instead, they should be inspected during routine servicing, especially if the vehicle tows, sees corrugated roads or coastal conditions.

Common signs a universal joint needs attention include:

• Vibration or shudder that follows road speed, especially under load
• Clunk on take-off or when shifting from reverse to drive
• Squeak or chirp at low speeds that changes with vehicle speed
• Visible rust dust around bearing caps or any free play at the joint

During servicing, a technician should check for play at each joint, inspect the centre support bearing, and look for damaged seals or impact marks. If replacement is needed, they’ll mark the flanges to maintain phasing, torque the flange bolts to factory spec, and ensure the shaft is correctly balanced. Using quality OEM or reputable aftermarket parts helps keep NVH in check.

For most Exiga owners, a quick driveline check every 20,000–30,000 km is cheap insurance. Catching a tired U-joint early prevents collateral damage to the tailshaft, exhaust, or rear diff, and keeps the smooth, planted feel that Subaru’s Symmetrical AWD is known for.

Popular questions

Does a 2016 Subaru Exiga have universal joints?
Yes. The AWD Exiga/Crossover 7 uses universal joints on the tailshaft between the transmission and rear differential. Front axles use CV joints. This layout is detailed in Subaru’s factory service manual driveline sections and reflected in Subaru parts catalogues for the YA-series Exiga.

What are the signs a universal joint is failing on an Exiga?
Typical clues are a speed-related vibration, a clunk when selecting drive or reverse, and a rhythmic squeak at low speed. Any free play at the joint or rust-coloured dust around the bearing caps also points to wear and the need for replacement.

Can the Exiga’s universal joints be serviced, or is the whole tailshaft replaced?
They’re generally sealed from factory and not greasable. Many Subaru tailshafts have staked U-joints, Subaru’s procedure is to replace the complete shaft. A driveline specialist can often rebuild and rebalance the shaft with serviceable joints if desired.
