I have a 1991 Buick Lesabre Custom with about 125,000 miles on it. I am noticing some issues with the suspension. The front drivers side and the rear passenger sides are sagging about an inch or more beyond normal. The other sides seem normal height. Should I replace all of the struts, or do i need to replace the springs as well? I am considering buying the Monroe Sensatrac complete kit, so I can just swap out the entire assembly, is this wise or should I just switch out the shocks. I figure the springs must be bad on the two sagging sides, or could this be cause by the shocks only? I'm not sure if the investment is worth it. I do plan to drive the car into the ground so i'll havce it for at least 3 or more years, and i drive on dirt roads alot. Any info would be appreciated. Thanks

Welcome to AF, the struts have no affect on standing height, suspension components, unibody straightness, tire size and springs all enter the picture.
