Parts for your 2017 Subaru Outback-Cv boots

2017 Subaru Outback CV boots — what they do and when to replace them

Yes, CV boots are fitted to the 2017 Subaru Outback. Subaru’s factory workshop manual (STIS) for the BN/BS Outback/Legacy platform and the Subaru Global Parts Catalogue (FAST) both detail front and rear drive shafts with inner and outer constant velocity joints protected by rubber boots. The front axle section and the rear drive shaft section in the manual specify boot service and replacement procedures, and the parts catalogue lists complete boot kit assemblies for each joint, confirming their use on this model.

On a 2017 Subaru Outback, the CV boots shield the CV joints from grit, water, and road grime while keeping the special moly grease right where it belongs. With Subaru’s Symmetrical AWD working all four corners, those joints articulate constantly over bumps, steering angles and load changes, so intact boots are crucial for long life and quiet running.

For day‑to‑day servicing, it’s smart to have the CV boots visually checked at each service or roughly every 10,000–15,000 kilometres—more often if the Outback sees gravel roads, beach launches, or lots of wet weather. A quick look behind the wheels and under the guards will spot small splits early, saving the joints themselves.

• Tell‑tales to watch for:
  • Grease flung around the inside of the wheel or under the guard.
  • Small cracks in the boot pleats or loose/damaged clamps.
  • Clicking on full lock or a shudder on take‑off (often means joint wear from running dry).

If a boot is torn but the joint hasn’t started clicking, a boot kit is usually the best-value fix. A proper kit includes the boot, new clamps and the correct CV grease. During replacement the joint is cleaned, repacked with high‑moly grease, the new boot is fitted and clamped with the correct ear‑type tool, and the axle nut is torqued and staked to Subaru’s spec. If the joint has already worn or pitted, a complete drive shaft assembly may be the prudent option.

Handy tips for Outback owners:

• Use quality neoprene/TPE boots—cheap “universal” stretch boots don’t last long off‑road.
• Avoid solvents on the rubber, a mild degreaser and water is fine.
• If suspension arms are separated during the job, ask for a wheel alignment check.
• Stick to the Subaru workshop manual procedures and specifications for best results.

How often should CV boots be inspected on a 2017 Subaru Outback?

They’re worth a look at every regular service, or about every 10,000–15,000 km. If the Outback frequently tackles gravel, mud, or beach work, shorten the interval. Early detection of a small split can save the CV joint from running dry and getting noisy.

Is it better to replace a torn CV boot or the whole driveshaft?

If the joint is still quiet and free of play, a boot kit with fresh grease is the cost‑effective way to go. If there’s clicking on turns, blueing, rust dust, or roughness when the joint is articulated off the car, a complete shaft is typically the smarter long‑term fix.

What are the signs a CV joint on a Subaru Outback is on the way out?

Common symptoms include a rhythmic clicking when turning, a vibration on acceleration, or grease sprayed inside the wheel from a split boot. Any of these warrant inspection—sorting a boot early can prevent the joint from failing later.
