2008 Expediton 4X4, 3.31 Ratio
I live in Tennessee, do a good amount of towing but only in the 3000-3500 lbs. range.
I have not taken a test drive, but suspect the 3.31 ratio 2008 Expedition in 4X4 would be a bit sluggish on hills to major disappointing in the mountains. Assume the fuel mileage would be a bit better due to the 3.31 ratio and the 6-speed tranny?. But, there are plenty of horror stories about lugging around with a taller axle ratio and in turn lower mileage. Obviously would expect trade off in engine performance in opting for the standard 3.31.
Current vehicle is a 2004 Expedition, NBX off-road version, 5.4L, 4X4. With the 3.73 ratio the vehicle seems to have good towing, hill climbing power. Fuel mileage is decent at say 15.4 to 16.2 mpg day in day out over 3.5 year period. 89,000 miles, brakes only out-of-pocket expense so far.
Any feedback on the 3.31 ratio for the 4X4 2008 Expedition?
