My 04 4.4 has been riding much rougher than usual so took it to my local indy to have a look. The leveling still works correctly. It appears that all four struts just stopped working at once. Basically if you try to "bounce" the car either in the front or the rear it's like pressing against a wall. I looked around the forum but didn't see anything similar. Anyone seen anything like this? He indicated I need to take it to the dealer and they can interpret the codes? Sound familiar?
