i have ford racing 4.10s in my car now. i am thinking of going with ford racing 4.56s. i have read somewhere where when swapping ford gears for ford gears you can directly swap em out. my only concern is that my 94 when we swapped the 3.08s for 3.73s i went with yukon gears, and it whined a little bit.

i only have 9000 miles on the car, and i believe the original owner replaced all the bearings and everything when he swapped 4.10s in, so if i can, i'm trying to avoid a install kit.

is it true i can just swap out the gears and not have to worry about adjusting backlash or anything if i go ford racing?

you will need to at least check the backlash and pinion depth. i would never just throw in a set of gears and call it good.

I believe 4.56 and up needs a special differential cross pin - its machined to clear the thicker ring gear

What you heard about Ford gear sets is usually true. You can almost always use the original shims and your depth and lash will be fine. Having said that you always want to double check to make sure after the install.
