I've had to replace the high and low pressure lines that go to and from the steering rack. Usually these have to be replaced because the crimped bit of metal that holds the rubber hoses onto the pipe corrodes and then allows leakage. In my case, I had to replace for other reasons. I'm aware that many people use jubilee clips to try to hold the corroding bits together but, at some point I guess they may let go.
The problem is, to replace these pipes is an expensive job. The pipes themselves run to about GBP500 for both and then the subframe has to be dropped to fit them, which is about 7 hours labour.
Here's a much cheaper way:
You can use 997 power steering lines. These don't require removal of the subframe but do require that you get some hoses made up to lengthen the line. So:
1. Purchase either second hand or new: 997.347.462.03 and 997.347.564.03 (see http://www.scuderiacarparts.com/dia...ering/power-steering-lines/135-519-20782.html).
These pipes have the correct connectors at both ends. They slot into the rack without having to remove anything. The problem, however, is that the lines are far too short. So, you need to lengthen the pipes so that they can attach to the connectors half way down the car.
2. Go to a hydraulic hose firm like Pirtek and ask then to lengthen the pipes by chopping off the connectors which are supposed to connect half way along the car and put 195cm of high pressure hose between the connector and the cut pipe.
3. You will need to sort out a modified route for the new hoses, but I found this quite simple. Remember, it's all hidden underneath plastic trays, so no one will see.
4. Variously cut and yank out the old pipework.
I managed to get second hand pipes and so the total cost was about GBP200 vs GBP1200 it would probably cost to have done with stock parts.
