A Diesel Nut
Well, to start, my 1989 Ford F-250 4x2 did have 4.10's in the rears, and swapped in a 10.25 axle with 3.55's in it. Love the rear axle, improved the driveability of my truck. My tires are LT265/75R16s and since the axle swap, I've been trying to find the right speedo drive gear. The truck had a 19 tooth gear, it now has a 18 tooth in it. By the way, my truck has the ZF s5-42 5-speed in it. The cruise control worked with the 19 tooth gear, now it doesn't work with the 18 tooth gear in it; my rear ABS light also (intermittenly) comes on with this new gear. Any help with this would be greatly appreciated. Also, in addition, my turns about 2,000 rpm to go a 60 mph (clocked it from mile marker to mile marker).
