Take a look at this pic:
This is at the FE last October.
When I was working on my truck, everything "seemed" OK...of course, it came w/o a front bumper, and the front sheet metal has been off since I got it. When I put the front clip on, and the front bumper, it became obvious that the bumper isn't level to the truck and ground.
The drivers side frame horn is about 1" lower than the passenger side. Across the width of the bumper, that magnifies into a 2" height difference, low on the drivers side of the truck, passenger side is high.
The frame, from level concrete, measures the same height at the rear spring hangers. At the bump stop, it's about 1/2" low on the driver side, and at the front spring shackle mount, it's almost 3/4"...then 1" at the end of the frame.
The driver side front spring shackle mount is not parallel to the passenger side mount...it's welded to the frame tilted back just a bit...this accounts for about 1/4" of the height difference it looks like, because the shackles sit at different angles from one side of the truck to the other.
There are no signs of a bent frame or frame damage and repair. It really looks like it was just built on a Friday by the lowest bidder.
It drives fine, doesn't pull or anything. Tires that came on it (ndt's) didn't have any wear pattern that would indicate a problem. The only real problem to me, so far, right now, is that the bumper doesn't line up.
I'm going to mount my winch anyway, and I'll "force" the new bumper to be horizontal when I bolt and weld up the frame extensions.
Anybody else seen this? Did I get the worst factory frame out there...or are others like this??
