thanks I will check that and let you know what I found

Yes my tires are inflated to 35 front 45 back as recommended

yes

I have a 2001 Ford Excursion with 39,000 miles on it. When I drive the vehicle on the freeways it has a tendencies to sway slightly. The front steering linkage is tight along with the ball joints. There is a shock attached to the front steering linkage and over the years has leaked fluid from it. Could the shock be the reason a get the sway?
