Parts for your 2013 Subaru Exiga-Universal joints

2013 Subaru Exiga universal joints: what they do and when to service them

Based on technical references including the Subaru Exiga (YA) Service Manual – Drivetrain & Differential: Propeller Shaft section (available via Subaru’s STIS/Global Technical Information System), and OEM parts catalogues for the YA-series Exiga, the 2013 Subaru Exiga uses universal joints (U‑joints) on its two‑piece propeller shaft. These sources describe a centre carrier bearing with cross‑type universal joints at the shaft ends. The Exiga’s front and rear axle shafts use constant‑velocity (CV) joints, but the prop shaft that sends drive to the rear differential relies on U‑joints for angular movement and length compensation.

On this seven‑seater, the U‑joints allow smooth transfer of torque from the transmission to the rear diff as the suspension moves and the drivetrain angles change. That flexibility helps keep Subaru’s Symmetrical AWD quiet and reliable, while maintaining correct driveline phasing. Many Exiga prop shafts are built with staked (non‑greaseable) U‑joints, in practice that means inspection is the go, and when wear is found, the usual fix is replacing the complete propeller shaft assembly or having a driveline specialist fit serviceable circlip‑type joints and re‑balance the shaft.

As part of regular servicing, it’s smart to have a mechanic check the Exiga’s prop shaft U‑joints every 20,000–30,000 km or annually, especially on vehicles that tow or see lots of city stop‑start. What they’re looking for is play, roughness, or red/brown dust around the bearing caps. Because there are typically no grease nipples, preventative care is mostly inspection and early replacement to avoid collateral damage to the centre bearing or diff flanges.

• Common symptoms of worn U‑joints:
  • Clunk on take‑off or shifting from reverse to drive
  • Squeak or chirp at low speeds that changes with road speed
  • Vibration or shudder under load or around 60–90 km/h
• Service tips:
  • Mark the prop shaft orientation before removal to preserve phasing
  • Use new flange bolts and the correct torque/threadlocker on refit
  • If replacing just the joints, insist on a balance check of the assembly

The upshot for Aussie and Kiwi owners: U‑joints are part of the Exiga’s AWD backbone. Keep an ear out for the tell‑tales, get them inspected on schedule, and sort any wear early to keep it smooth and drama‑free on the school run or the ski trip.

Popular questions about 2013 Subaru Exiga universal joints

Does the 2013 Subaru Exiga actually have universal joints?
Yes. Technical documentation for the YA‑series Exiga specifies universal joints on the two‑piece propeller shaft. The wheel drive shafts use CV joints, but the prop shaft to the rear differential uses U‑joints to handle angle changes and torque transfer.

How often should the Exiga’s U‑joints be checked?
Have them inspected at least every 20,000–30,000 km or annually during routine servicing, sooner if there’s vibration, clunks, or squeaks. Because most are sealed and non‑greaseable, early detection is the best way to avoid a complete shaft replacement.

Can the Exiga’s U‑joints be replaced, or is it a full shaft job?
Many Exiga prop shafts use staked U‑joints, so Subaru’s standard procedure is to replace the prop shaft assembly. A competent driveline specialist can often fit serviceable circlip‑type joints and re‑balance the shaft, which may be a cost‑effective alternative.
