Hi,
the video gives you a step by step tutorial how to remove and how to install the steering gear on a Porsche 911 G. The original tie rods are replaced by the tie rods of the turbo model. These tie rods have a ball joint instead of the cardan universal joint of the non turbo versions, which makes them much stiffer.

The video has a German soundtrack but English subtitles are available on YouTube.
Enjoy it,
Jürgen
