Which 03 (or 04) Cobra Rack?
I just went through this pain this weekend folks - here's what I learned. I have a 2004 Cobra and blew a steering rack seal on Friday. The seal leaked into the driver's side boot and it actually blew! I went to Advance Auto Parts and they ordered a reman rack. Of course I had no idea at the time there was a ZK and a ZM code. Received the new one but when I went to install it, I realized the pinion shaft was 180 degress off from the one I took out. I rotated the shaft 180 and installed it... but now, of course, my steering wheel is perfectly upside down. I was unaware (until I drove up to the Ford dealership) that there was NO other adjustment to straighten the wheel. He said I either have a wrong part, or when they rebuit the unit some idiot installed the pinion shaft backwards. Now that I've been reading posts and other pages, it appears I ordered the SPR-ZK and I really need the SPR-ZM. I have both a ZK and a ZM on order from Advance Auto (supplier is CARDONE), so one of them has to be right. Now I just get the absolute joy of pulling that rack back off! So, it may not only be the ratio or bushing stiffness, but it might also be a completely different pinion shaft rotation. Anybody else experienced this???
