I just recently bought a 2005 Excursion, it now has 44000 miles on it. I just had all the motor work in my signature done. I think the motor is good, would like to get a powermax and inspectors, but first I got to do something.g about the handling done on this thing. It is downright scary on the interstate. I just got back from a 1600 mile trip and my hands hurt from gripping the wheel so hard. Whenever I hit a bump it is like the truck gets squirly from side to side, it is almost feels like pulling a trailer with heavy tail weight, but it was. with no trailer. I also noticed it some when coming around semi trucks. It doesn't have any lift, has brand new 285 cooper tires and the steering is tight. If it is this bad with no trailer I am scared to see what it will be like with any of my trailers.I bought this as mainly a tow vehicle for my 10,000 lb camper, my 30 ft boat and my car hauler trailer and carry the family. It is definitely not safe the way it is, after traveling through the hills in North Carolina and Tennessee, the handling on this thing is now priority one, somebody help please! I know handling on these is a known issue, I just don't know how to correct it. If anyone can tell me how to fix it, with a parts list, it would be greatly appreciated. As far as the motor, wow!, it runs good.
