Detailed Description

This GKN Loebro CV axle assembly, part number 306166, is engineered for rear left applications on the 2008-2009 Smart Fortwo. The axle uses a 33-spline inner and outer design, a plunging inboard joint, and a fixed ball outboard joint to support smooth torque transfer and suspension movement in the original vehicle layout. The integrated 42-tooth ABS tone ring helps maintain wheel speed signal compatibility where equipped. This part cross-references OE numbers 451 357 05 01 and 451 357 07 01 for the same application.

What This Axle Assembly Helps Address

  • Clicking or popping noises during turns from worn CV joints
  • Vibration or shudder during acceleration from axle wear
  • Grease leakage from a damaged CV boot or joint area
  • ABS warning concerns related to a damaged tone ring
  • Driveline looseness caused by internal axle wear

Installation Notes and Tips

Verify rear left fitment on the Smart Fortwo before installation and confirm spline count, compressed length, and axle nut thread size against the removed part. Inspect the hub, seals, and surrounding suspension components for wear before installing the new axle. Use proper torque procedures for the axle nut and follow the vehicle service manual for final tightening and ABS system checks.

Quality Assurance

GKN Automotive supplies OE technology to global vehicle manufacturers and produces axle assemblies for a wide range of passenger vehicles, including compact cars and light trucks. Part number 306166 reflects that OE-focused engineering approach for the Smart Fortwo driveline application.
