I guess what's being asked is if the bumper is tilted down due to being attached that way, or it the X's nose is now lower due to the weight?
The easiest way to tell is the fender line to bumper line...if it looks level with the matching edge of the fender line (Passenger/driver fender lines...), then the front end can be sagging, as in the suspension, and a t-bar tweak will fix it.
If the bumper is drooping relative to the fender lines, then you just need to loosen the frame horn bolts enough to readjust the angle of the bumper, and re-tighten at the correct position.
If you are having trouble determining the above, a few pics from the two sides and front of the X would help us to let you know.
Have fun!
