Febi Bilstein Gen 5 Haldex Repair Kit

Complete Febi Bilstein service kit. Fits various Volkswagen, Audi, SEAT, Škoda and Cupra models equipped with four-wheel drive and a 5th generation Haldex coupling.

Problem

Whining noise from the rear of the car, which could be misdiagnosed as a wheel bearing.

Cause

The rear differential taper roller bearings have become pitted and worn. This could be due to the rear differential oil not being replaced at the set service intervals or the incorrect oil has been used.

Solution

Febi have developed a Repair Kit for this differential unit which includes the bearings, seals, fixings and oils, which is not available from the vehicle manufacturer. This offers a more economical repair solution than replacing the complete differential unit. The rear differential unit needs to be removed from the vehicle to carry out the repair, which will vary from model to model. First drain the differential and Haldex oils, and then remove the rear exhaust section, anti-roll bar, propshaft and driveshafts. To access the three retaining bolts, one can be reached from underneath the vehicle, while the other two can only be accessed by drilling holes in the floor of the luggage compartment at the designated points (Fig. 1) provided by the vehicle manufacturer for this purpose. Alternatively, the complete rear axle assembly and subframe can be removed from the vehicle to remove the differential unit.
