If you can see the driveshaft turn as the truck moves, the rear axle has definitely been replaced. Try posting some links to pictures at somewhere like Photobucket, Hunt 101, etc., and somebody can probably make an educated guess at what's in there now. Posting pictures directly to the site creates problems for some of our members with limited bandwidth or very expensive internet access, so no direct-posted pics, please. Does the rear end still have the 6-lug wheels on it?
