Due to the inaccessibility of the internal threaded connection -1, the wishbone can only be removed with the subframe removed. Before starting work, measure the distance -a- from the center of the wheel to the lower edge of the wheel well, while the wheels are not yet removed from the vehicle. Place the vehicle on a lift. Remove the wheels. Remove the subframe. Mark, for example with a felt-tip pen, the position of the eccentric bolt -2- relative to the wheel bearing housing. Release screw connections -1- and -2-. Remove the upper wishbone -3-.
Installation
Replace bolts and self-locking nuts.
Mounting position of the upper wishbone on the subframe
Screw the upper transverse link -3- to the threaded connection -1- by hand. Place a flat iron strip or straight strip -1- evenly on the upper wishbone -arrows-. Install the upper transverse arm -2- so that the dimension is equal to a = 8 mm±1 mm between the bar -1 - and the stamped corner of the upper transverse arm -2-.
Tighten the threaded connection of the upper wishbone -3- in this position on the subframe. Screw the hub bearing housing to the wishbone and tighten the new nut to a torque of 20 Nm. Observe the installation position of the eccentric washer -2-. Install the subframe. Unscrew bolt connection -1-. Raise the wheel support to the vehicle's curb weight position and tighten bolt connection-1-.
Tighten the wheel. Adjust the wheel alignment angles.
