Hello I have the F-150 and just put the bearings, 4-wheel drive, and stage 2 motor in. The truck is now very boggy and the gears that run the drive shaft threw the middle make slipping noises everyonce in a while. I figured out that one gear was spicifcally for the front and one for the back because I put them in wrong at first. funny, the instuctions never mentioned a thing about the little red gears being different. or are they not suppoesed to be? Even back in two wheel drive with the stage 2 and bearings it still just doesn't seem to have a lot more power like I would expect it to simalar to the old xmods. any thoughts? thanks
