Go to this website and look to the left for steering. There are two links for power steering rack replacement. I used these when I did mine a few years ago, and, except for one stupid mistake I made in re-assembly, all went well.

Replacing the rack with a rebuilt unit seems like the way to go. Bentley seems light on "how to" details. Can someone point me to a link with nice clear step by step instructions on this job?> Thanks,> George> 85' Westfalia
