Parts for your 2013 Subaru Legacy-Cv boots

2013 Subaru Legacy CV boots — what they do and when to replace them

Yes, the 2013 Subaru Legacy uses CV boots on both front and rear drive shafts. This is confirmed by the Subaru Service Manual for the 2013MY Legacy/Outback (Drive Shaft section), which details inner and outer constant velocity joints and their protective rubber boots, and by Subaru’s Genuine Parts catalog, which lists boot kits for the front and rear axles on this model. Independent workshop references such as Haynes and trade databases like Mitchell1/ALLDATA also specify CV joint and boot inspection and replacement procedures for the 2010–2014 Legacy platform.

On this all-wheel-drive Subaru, CV boots are the tough rubber or thermoplastic sleeves that keep the CV joints clean and well-lubed. They trap the grease inside the joint and keep road grit, water, and dust out. That’s crucial, because once a boot splits and the grease flings out, the joint can chew itself out in short order—often turning a simple boot job into a full axle replacement.

As part of regular servicing on a 2013 Legacy, it’s smart to give the CV boots a proper look. They live right behind the wheels at each end of the drive shafts. A quick torch check for cracks, splits, loose clamps, or grease spray on the inside of the wheels can save a lot of coin later. In Australia and New Zealand conditions—heat, UV, and plenty of wet or unsealed roads—rubber can harden and perish faster, so periodic inspections are worth it.

• Typical signs of trouble: clicking on turns, vibration under load, grease slung around the wheel arch, or a damp, greasy boot.
• Inspection timing: every service or at least every 10,000–15,000 kilometres, sooner after off-road, beach, or floodwater drives.
• If a boot is torn but the joint is quiet: a boot-only replacement and fresh grease can be all that’s needed.
• If there’s noise, rust-coloured grease, or play in the joint: consider a complete axle assembly—often faster and cost-effective.

When replacing a boot on the Legacy, use the correct Subaru-spec boot kit and clamps, clean the joint thoroughly, and pack the specified quantity of high-moly CV grease. Proper clamp tension is key, loose bands will weep, tight bands can cut the boot. After refitting, check for smooth articulation lock-to-lock and under suspension travel, and re-torque the axle nut to the manual’s spec. A tidy wheel alignment check afterwards never hurts.

Look after the CV boots and the Legacy’s AWD driveline will keep pulling strongly for many kilometres without drama.

• How often should the CV boots be inspected on a 2013 Subaru Legacy?
  They’re best checked at every routine service or at least every 10,000–15,000 kilometres. If the car sees gravel, beach runs, or lots of rain and puddles, shorten the interval. A quick look for grease fling or cracking rubber can prevent joint damage.
• Can just the boot be replaced, or does the whole axle need doing?
  If the boot has only just split and the joint is still quiet and smooth, a boot kit and fresh grease usually sorts it. If there’s clicking on turns, heavy wear marks, or contaminated grease, a complete axle is often the better bet.
• What are the classic signs a CV boot or joint is failing on a 2013 Legacy?
  Grease on the inside of the rim or guard, visible cracks or tears in the boot, clicking when turning, vibration under acceleration, or a knocking noise over bumps all point to boot or CV joint issues.
