does anyone know the correct backlash and preload settings for an 87-93 8.8 rear, and also is it the same all the way up to 04

I know for SN-95 Mustangs with the 8.8" the correct backlash is anywhere between .008-.012. You want to get them as tight as you can, because as the gears wear, they loosen up. I even know a Ford rear end specialist that sets his rear ends to .004.

.008-.014 is what I set them at. Like MF stated, go with the low side. If the gears are set at the max, you run the risk of there being noise later on.
