Rack and Pinion Replaces - stiff steering
#1
![Default](/forum/images/icons/icon1.gif)
Hey Jag Fam!
I just replaced the rack and pinion and tie rods on my X308, XJR. I replaced it with a brand new Rack. Everything came together well, but now the steering is a little stiff. Is it because it's a new rack and it needs to be worked in? Otherwise, any ideas why it is stiffer and should I fix it?
Many thanks all!

My first suspicion is that the electrical connector at the steering rack pinion housing may not have been reconnected properly. The ZF Servotronic steering system uses electronically-controlled variable power assist. The default mode is low assist, for driving at highway speeds. As speed is reduced, power assist is increased. Maximum assist is applied for low-speed cornering and parking. So if the wiring harness was not reconnected to the rack, or if the electrical connector is contaminated with oil or power steering fluid, your rack may be in the default low power assist mode.
At the link below you can download a section on steering from JTIS, excerpted by Jim Lombardi:

Hi,
I wanted to let you know that I had the same issue above on my 01 vdp/sc with the steering being stiff. After reading the above suggestion, I found that I had inadvertently pulled the red/yellow wires out of the connector that leads down to the steering rack sensor while working on getting the AC compressor out. Once reconnected, the steering worked properly again. Thanks!
