2019 Subaru Impreza CV Joint: Purpose, care and when to replace

Yes, a CV joint is absolutely relevant to the 2019 Subaru Impreza. Technical sources including the Subaru Service Manual (2019MY Impreza, Drive Shaft System and Rear Axle sections), the Subaru Genuine Parts Catalogue (front drive shaft assemblies, outer/inner CV joints and boot kits), and Subaru Technical Information System materials all describe the vehicle’s front (and on AWD models, rear) halfshafts that use constant velocity joints. These joints are fitted as standard equipment to transmit drive smoothly while the suspension moves and the front wheels steer.

The CV joint’s purpose is to deliver engine torque to the wheels at a constant speed without vibration, even at sharp steering angles and through suspension travel. On the Impreza, the outer joint is a fixed ball-type joint handling large steering angles, while the inner joint is a plunge-type (often a DOJ) that slides in and out to account for suspension movement and length change. For AWD variants common in Australia and New Zealand, there are also rear halfshafts with CV joints doing the same job at the back.

Servicing is mainly about boots, grease and inspection. At regular services, the boots should be checked for cracks, splits or loose bands, and any sling of dark moly grease around the inside of the wheel or control arms. Catching a torn boot early and fitting a new boot kit with the specified grease quantity can save the joint. If a joint is already noisy (classic clicking on full lock, or shudder under load), the usual fix is a replacement shaft or joint assembly.

• Common symptoms:
  • Clicking or knocking on tight turns (outer joint wear)
  • Vibration under acceleration (inner joint wear or excessive play)
  • Grease spray near the hub or subframe (torn boot)
• Replacement tips for the Impreza:
  • Use quality parts matched to VIN, left and right shafts can differ.
  • Fit new boot bands and the correct moly CV grease amount.
  • Always use a new axle nut and stake it, tighten to the Subaru spec.
  • After installation, check for ABS wire clearance and no boot twist, then road-test for noise on full lock.

With normal city and highway driving, many Impreza CV joints last well past 150,000 km if the boots stay intact. Regular inspections and prompt boot repairs are the best way to avoid a bigger bill later.

Popular questions about 2019 Subaru Impreza CV joints

Do all 2019 Imprezas have CV joints, including AWD models?
Yes. All 2019 Imprezas use CV joints on the front drive shafts. AWD versions also have CV-jointed rear halfshafts. This is confirmed by Subaru’s service manual and genuine parts listings for both front and rear axles.

What are the tell-tale signs a CV joint needs attention?
Owners typically notice clicking on full lock at low speed, grease flung around the inner guard from a torn boot, or a shudder on acceleration. Any of these warrant inspection, a clean tear with no noise may be saved with a boot kit, while noise usually means replacement.

Boot-only repair or full shaft replacement—what’s best?
If the joint is quiet and play-free, a new boot and fresh grease is a cost-effective repair. If there’s clicking, roughness or blueing/pitting inside, replacing the complete shaft or joint assembly is the reliable route, and often saves labour time.
