113-501-231 VW Beetle & Ghia Rear Axle Stub - 8mm Threads (1969-1979)

Rear Axle Stub (Standard Size, 8mm Threads) – 113-501-231

The 113-501-231 is a critical drivetrain component for late-model air-cooled Volkswagens. Over decades of use, these stub axles can suffer from stripped inner threads due to over-torqued CV bolts, or worn outer splines caused by loose axle nuts. A damaged stub axle leads to dangerous wheel play, brake drum damage, or loose CV joints. Installing this high-quality, factory-dimension replacement restores a tight spline fit and ensures your rear suspension operates safely and quietly.

This axle stub is sold individually and fits either the driver or passenger side of IRS-equipped Type 1 models.

Installation & Maintenance Tips

• Check Your CV Bolt Size: While 1969-1979 Type 1 models standardly used 8mm threads, some high-performance or modified cars upgrade to the larger Type 2 (Bus) CV joints which use 10mm bolts. Always verify your bolt size before ordering.

• Torque the Axle Nut: The large outer castle nut requires massive torque (typically 217 ft-lbs). Failing to torque this nut completely will cause the new stub axle splines to strip out inside the brake drum within a few miles.

• Replace the Seals: Whenever pulling the stub axle out of the trailing arm, always install new inner and outer wheel bearing grease seals and a fresh cotter pin for the castle nut to ensure a leak-free repair.
