2010 Subaru Impreza CV boots: what they do and when to replace them

CV boots are absolutely used on the 2010 Subaru Impreza. Technical sources including the Subaru Factory Service Manual for the 2010 Impreza (Driveline/Axle section), Subaru genuine parts catalogues listing inner and outer CV boot kits for GE/GH/GR models, and aftermarket service manuals covering 2008–2014 Impreza all specify front and rear driveshafts with constant velocity joints protected by rubber boots. These references describe inspection, removal, and replacement procedures for the boots and their clamps, confirming the part is relevant to this vehicle.

On the 2010 Subaru Impreza, the CV boots are the flexible rubber bellows that protect each constant velocity joint on the front and rear driveshafts. Their job is simple but critical: keep high‑moly grease inside the joint and keep water, grit, and road muck out. When the boot stays intact, the joint runs smoothly for ages. When a boot splits, grease flings onto the wheel arch and suspension, the joint runs dry, and wear accelerates fast—especially on Aussie and Kiwi roads with plenty of gravel, puddles, and salt air.

As part of regular servicing, it’s smart to have the CV boots inspected every 10,000–15,000 kilometres or at each oil service. Many WOF and roadworthy inspections will also flag a seeping or torn boot. Catching a small crack early usually means a straightforward boot-and-clip kit replacement with fresh moly grease. If it’s been driven for a while with a split boot and there’s clicking on turns or vibration on acceleration, the safer call is a new joint or complete shaft.

• Watch for tell-tales: grease spray on the inside of the rim or guard, a rubbery smell after a drive, clicking on tight turns, or shudder under load.
• When replacing a boot, use quality clamps and the specified molybdenum disulphide CV grease. Make sure the boot isn’t twisted and the clips are fully seated.
• Avoid lifting or supporting the hub by the shaft, which can stress the boot. After any axle work, torque the axle nut to spec and recheck for leaks after a short drive.
• If the Impreza sees beach runs, rural gravel, or frequent potholes, shorten inspection intervals—environment is everything for boot life.

Front and rear boots differ in size and design (outer Rzeppa vs inner DOJ/EBJ), so ordering by VIN or driveline code is the safest way to get the right kit for this Impreza.

Popular questions about 2010 Subaru Impreza CV boots

How often should CV boots be checked on a 2010 Impreza?
They’re best checked at every service—about every 10,000–15,000 km or 6–12 months. If the car sees gravel, coastal roads, or heavy rain, look more often because grit and salt accelerate cracking.

Can a split CV boot be patched, or does it need replacing?
Patching or taping won’t hold grease or keep water out once the shaft spins. Replace the boot promptly. If there’s clicking on turns or visible joint play, plan on a joint or complete driveshaft instead of just the boot.

Are the front and rear CV boots the same on this model?
No. The front outer, front inner, rear outer, and rear inner boots can all be different. Inner joints often use a different style than outers. Order by VIN or exact model/engine/driveline to get the correct boot kit and clamps.
