the wifes car has started playing up, its a 1.6 zetec escort and the steering keeps going all vague, its like a delayed reaction, if you turn the wheel nothing happens for a second or so, seems to be ok at around 20mph or less, but its kind of like driving on ice,is this a symptom of the power steering pump on its way out? it had a new rack fitted about 6 months ago, so i assume thats ok, the steering column joints are tight , any ideas?cheers for any help, nick
