Is it worth the money to switch from 3.73's to 3.55/3.58's?
I have 1.6M on my truck. I have to rebuild the power divider and front drive axle. It will cost me about $3000 to do this. I have an opportunity to do a complete swap for 3.55/3.58 for the same money. The rears will come out of a 244K truck. . The axles are exactly the same except the gears. Will it be cost effective and will I have any fuel mileage gain?
Is this a worthwhile discussion?
