Replacing wheel bearing housings (wheel carriers): Notes

Wheel carriers with a short steering arm (original version / dimension X = approx. 124 mm) and wheel carriers with a long steering arm (optimized wheel carriers) (dimension X = approx. 147 mm) are available from the Parts Service.

Use of wheel carriers with the long steering arm - in production - partly in the current model year 1999 (X), but generally as of model year 2000 (Y).

Wheel carriers with the short steering arm - dimension X = approx. 124 mm - will remain available.

The retroactive installation of wheel carriers with a long steering arm - only in pairs - is permissible! When installing wheel carriers with a long steering arm for the first time, the following parts must be used:

  1. A differently shaped stabilizer (for reasons of space).
  2. Optimized tie rods (toe control arms) with harder rubber mount.

In general, the following applies: Only wheel carriers (wheel bearing housing) of the same version - long or short steering arm (dimension X) - may be installed on any one vehicle.
