Detailed Description

GKN Loebro 306649 is a CV axle assembly engineered for rear left service on 2005-2008 Porsche Boxster and 2006-2008 Porsche Cayman models. The assembly uses plunging VL-style joints at both ends, a 28-spline outboard connection, and a compressed length of 25.472 inches to match the specified driveline layout. As an OE-technology driveline component from GKN Automotive, this axle assembly reflects the dimensional and joint-design requirements used in modern passenger vehicle drivetrains, including performance-oriented Porsche applications. This part cross-references Porsche 987.332.024.23 for the same application.

What It Helps Solve

  • Clicking or popping noises from a worn CV joint
  • Vibration during acceleration from a damaged axle shaft
  • Grease leakage from a compromised CV boot or joint area
  • Excessive driveline play affecting rear axle operation
  • Fitment issues when replacing the rear left axle on Porsche Boxster or Cayman models

Installation Notes and Tips

Fits 2005-2008 Porsche Boxster, rear left. Fits 2006-2008 Porsche Cayman, rear left. Verify spline count, axle length, and axle nut thread size before installation. Inspect related hub, seal, and suspension components for wear during axle replacement. Confirm the rear left position and match the original driveline configuration to the vehicle before final assembly.
