Hi guys I currently own a 1999 Ford Ranger 4X4 but was recently thinking about moving to an explorer 4X4 and then the thought occurred to me what about the Expedition, I had 2001 Super crew and really liked it, I have been doing some research but one thing I can't seem to get a definitive answer to is what kind of front suspension does the Expedition use I have seen what looks like torsion bars and read about air bags and even seen some schematics showing coil springs. Can someone clear these muddy waters? Thanks. I know what I might be getting into with the 5.4 but the Expedition size and capabilities for a daily driver and a weekend overland type rig seems just right.
