For vehicles with PDCC (Porsche Dynamic Chassis Control - anti-roll stabilization):
On vehicles with PDCC, the lines (pressure line, return line) at the PDCC valve block must be disconnected from rear axle to front axle. Unclip them if necessary. Allow fluid to flow into a suitable drip pan.
For installation, it is a good idea to mark the installation position of the rear axle housing diagonally in at least two places on the body. To do this, place the marks vertically with respect to the floor of the body using a felt-tip pen (e.g. mark along the rear axle housing mount with the pen). → Marking (example)
