2010 Subaru Impreza CV Joint: purpose, care, and when to replace

According to technical sources including the Subaru Factory Service Manual for the 2010 Impreza (Drive Shaft/Front Axle and Rear Axle sections) and Subaru’s official parts catalogue for GE/GH/GR/GV models, this vehicle is fitted with constant velocity (CV) joints. The front drive shafts use an outer EBJ/Birfield (Rzeppa-type) CV joint and an inner DOJ (double offset joint). All 2010 Imprezas have CV joints at the front, Symmetrical AWD models also have rear halfshafts with CV joints. These references confirm a CV joint is absolutely relevant on a 2010 Subaru Impreza.

On this Impreza, the CV joints let the wheels turn and the suspension travel whilst keeping drive smooth and quiet. They’re packed with special moly CV grease and sealed by flexible rubber boots. Keep the boots happy and the joints tend to last ages, let a boot split, and the grease flings out, water and grit sneak in, and the joint will start clicking on turns before long.

Good servicing for a 2010 Subaru Impreza CV joint is mostly about inspection and prevention. At each service, a quick look under the front (and rear on AWD) for torn boots, sling marks of dark grease on the inner guard or strut, and play in the shaft pays off. If a boot is cracked or leaking, get it re-booted promptly with the correct clamps and CV grease. Once a joint is noisy or has detectable looseness, replacement of the shaft assembly is the smart move. Many workshops fit complete axle shafts because they’re faster, often more economical, and come with fresh joints and boots.

• Watch for symptoms: clicking on tight turns, vibration under load, shudder on take-off, or fresh grease around the hub/underbody.
• Use quality parts: OEM or reputable aftermarket shafts/boots with the right molybdenum-disulphide CV grease.
• Mind the details: correct clamp tension, clean mating faces, and proper axle-nut torque and staking to protect bearings and joints.

Driven sensibly and kept sealed, the Impreza’s CV joints will rack up plenty of kilometres. If the car sees gravel roads, heavy rain, or frequent full-lock manoeuvres, shorten inspection intervals a bit—cheap insurance for a smooth, quiet driveline.

Popular questions

How long do CV joints last on a 2010 Subaru Impreza?
With intact boots and regular inspections, they can last well beyond 150,000–200,000 km. Harsh conditions, lifted suspension, or torn boots can shorten that dramatically, so catching boot damage early is key.

Can just the boot be replaced, or does the whole shaft need changing?
If the joint is still quiet and free of play, a new boot and fresh CV grease is fine. Once there’s clicking, rumbling, or metal flake in the grease, it’s better value to replace the complete driveshaft.

What noises point to a failing CV joint?
Outer joints commonly click or clack on tight turns under throttle. Inner joints can cause vibration or shudder on acceleration. Any grease fling or split boot is an early warning to check it out before noise starts.
