A-Premium Front CV Axle Shaft Assembly for Subaru Forester/Impreza/XV Crosstrek — Driver or Passenger Side, OE Fit with Axle Nut

The A-Premium front CV axle shaft assembly is a direct-fit replacement for select Subaru Forester, Impreza and XV Crosstrek models, delivering drivetrain torque from the transmission to the wheel with OE-style dimensions and included axle nut.

If your vehicle exhibits clicking during turns or grease on the inside of the wheel, a worn constant velocity (CV) axle may be the culprit. This A-Premium assembly is engineered to match factory spline counts and compressed length so you can restore smooth power delivery without custom modification. It ships with a standard neoprene outboard boot and the necessary axle nut, making installation straightforward for technicians and experienced DIYers.

How will this part affect my vehicle’s drivability after replacement?

Replacing a deteriorated CV axle with a correctly sized assembly restores consistent torque transfer to the wheel and reduces vibration, noise or clicking associated with worn joints. Properly installed, the axle operates transparently under acceleration, cruising and cornering without altering vehicle geometry.

• Eliminates clicking noise during turns when the joint was failing
• Reduces vibration caused by uneven or damaged splines
• Maintains original drive feel when matched to correct model and side
• Fits with factory spindle nut thread and supplied axle nut for correct torque
