Yep, and they wear out, often, and the reman racks commonly available are crap(surprise).
The good news is there is a guy on ebay that sells a delrin replacement bushing for that rack, and for
the aftermarket one(different size) pretty cheap.
You pull the inner tierod, put bushing on with spacer and nut, and turn the wheel to pull it into
place, it snaps in a little spot in the rack that is smaller, and pushes the old one in out of the way.
Works like a charm. There is ton of info on VW Vortex's forum about those racks, look for
Quaif quick ratio upgrade stuff to find some of it when searching.
