Best Steering rack for Volkswagen Passat

So the ZF steering rack finally got through customs and arrived safe and sound - thanks UPS. The rack is originally from a VR6 Passat so in theory should be up to the task. Got it installed and hooked up and so far no leaks. Immediately I noticed the pump is a lot quieter connected to this rack than it was when connected to the TRW rack which makes me think the TRW rack couldn't handle the pressure coming from the pump? Or maybe there was just something wrong with it internally. So far no leaks from the ZF rack so fingers crossed it'll hold up well when I get it back on the ground and go for a test drive.

I can confirm, I had to change the rack on my 2001.5 Passat because the steering wheel was loose and they are in fact interchangeable.

Put a used w8 rack in that had 66k on it. Tested it out before I buttoned it all up, seemed great. Buttoned it all up, drove a few miles on a test drive, no issues or noises at all.

Wow, adjusting the steering rack tension made a huge difference, car feels way more responsive now.

Leaking after OEM rebuild kit. On a g60 Passat Syncro, with TRW steering rack, with the VAG rebuild kit, the leaking continues.
