I need some suggestions, over the last few months I have noticed a reduction in my power assisted steering. From a stop or at low speed, such as trying to make a u-turn, my steering wheel is unnervingly hard to turn, the thing just doesn't want to move. I know Excursions seem to have a poor steering radius to begin with but this is nuts, it recently started getting worse, to the point of frustration. I have also noticed she seems to wander on the road more than my significant others, I realize with the lift kit, different tires, etc..., she won't handle the same but he seems to think there is a mechanical issue. ANY SUGGESTIONS???!!!!
