Febi 1K0-407-271-KB Front Left CV Axle Shaft Assembly

The Febi Bilstein 1K0-407-271-KB is a complete, ready-to-install CV axle half-shaft assembly engineered for the front-left drivetrain position on Volkswagen Group (VAG) vehicles. Also referenced by Febi internal part number 181245, this drive shaft is a direct-fit replacement for automatic transmission, front-wheel-drive (FWD) variants built on the PQ35 and related transverse-engine platforms.

As a full assembly, this unit includes the inner and outer constant-velocity (CV) joints, shaft, and protective boots — delivering everything needed to restore proper drivetrain function. The CV joints maintain smooth, consistent power delivery from the transmission to the front wheel throughout the full range of steering motion, even under varying road conditions.
