Once I put the front diff in backwards and the rear in correct, and the thing wouldn't roll at all.

#1- Check the assembly manual, and ensure your diffs are aligned correctly. Probably your prob right there, especially since you just installed a spool.

I have done that before as well, except I had put then both in backwards, so forward was reverse and vice versa.

When you look at the front of the truck, the screw heads that hold the diff together should face to the right. When you look at the back, the screw heads should also face to the right.

if ur truck is reverse equipped put it in reverse and forget about it also it could be jammed in reverse

take out diff... invert it... you got it in backwards...
