I bought a 2003 Ford F150 4X4 XLT from a dealer. It's
perfect, except when I use the high and especially the
low 4X4 I get quite a roaring sound from under the truck.
Is this normal?

I've driven Ford F150s for years, but never had a 4X4. On
that note, any advice about using 4X4s in the snow and
hauling firewood up somewhat steep inclines?

Thanks,

Mike
