What size is the axle nut on a Subaru Legacy?

The standard axle nut size for a Subaru Legacy is 32mm. This nut secures the wheel hub assembly to the vehicle's suspension system and is an important component for maintaining proper wheel alignment and safe driving.


Understanding the Subaru Legacy Axle Nut


The axle nut on a Subaru Legacy serves a critical function in the vehicle's suspension and wheel assembly. It is responsible for securing the wheel hub, which contains the wheel bearings, to the vehicle's suspension components. This ensures the wheel can rotate freely while maintaining proper alignment and stability.


The axle nut is a large, thick nut that is tightened to a specific torque specification to prevent the wheel hub from loosening or separating from the suspension. Proper torque is essential to avoid potential safety issues, such as wheel separation, that could lead to a loss of vehicle control.


Replacing the Axle Nut



  • When replacing the axle nut, it is important to use the correct 32mm size to ensure a proper fit.

  • The nut should be tightened to the manufacturer's recommended torque specification, typically around 150-180 ft-lbs of torque.

  • It is recommended to use a torque wrench to ensure the nut is tightened to the proper specification.

  • After tightening the nut, the wheel should be checked for any play or looseness to confirm the assembly is secure.


Proper maintenance and replacement of the Subaru Legacy's axle nut is crucial for maintaining the vehicle's safety and performance. Consulting the owner's manual or a professional mechanic is advised to ensure the correct procedures are followed.
