Gears & Axles - ABS sensor on Ford 9"

I just put a Ford 9" in my car and i am woundering what to do with the abs sensor.

Also if someone can help me with this little problem. The car moves in 1st 2nd and 3rd fine. But when I put it in 4th it will not go any where.

And why are people losing power with the Ford 9"

If you have 3 channel ABS you leave the sensor off and stare at your ABS inop light - nothing you can do except take the dash apart and block off the LEDs..

If you put the car in OD and doesnt move either your shifter isnt adjusted right or your trans has problems..

9" fords lose power over a 10 bolt because the internals are heavier plus the way the pinion is postioned on the ring gear (more below the ring gear CL then most) is great for strength but creates more friction then a 12 bolt/8.8/dana 60 ect..
