The steering reaction feel on my 2.7 has become uneven. Normally it's very smooth but just lately just as you begin to turn left or right there is a resistance felt and when you get passed it it goes smooth again, this is repeated when you return to straight ahead. Can Anybody give me a clue.

 

As it doesn't sound like you can DIY it, take it immediately to someone competent - your life depends on making sure it's safe.
