Steering and chassis

Steering and chassis

From MY 2004, the Corsa-C will be fitted with a revised steering knuckle, in conjunction with EPS steering. Variants with manual steering will continue to be fitted with the steering gear used up till now, which has a ratio of 24:1.

From MY 2004, Corsa-C variants with EPS steering will be fitted with a steering gear with a revised ratio of 15:1 (up till now 16.2:1). The modification has improved vehicle handling and, thanks to the shorter ratio, the driver will experience a sportier feel to the steering.

A reduction in steering travel was also necessary where the Z 17 DTH engine is used in conjunction with 15" wheels. This is to prevent the wheels from grinding against the wheel housing. In addition, different tie-rods were also installed on the Z 17 DTH engine variant.

From MY 2004, therefore, two different tie-rods will be in use. The only difference between them is dimension X on the axial joint, as shown below. The tie-rods used up till the end of MY 2003 must not be used in service operations for vehicles from MY 2004 and are therefore not listed in the following.

Catalogue number: Part number: Dimension X: Type of steering: 16 03 017 26 110 430 10.5 mm mechanical / EPS 16 03 018 26 110 431 6.5 mm EPS for Z 17 DTH

•  Service:
It is important that the tie-rods are not mixed up, as, apart from having a different turning circle, the tyre may grind against the wheel housing. The above-mentioned part and catalogue numbers refer to the service kit comprising tie rod and lock nut.
