Bent front crossmember...
 

After my accident my front crossmember is bent on the left side, is there anyway to straighten it back out so my bumper will be straight?

either a frame shop, or backyard way. Strap your hitch to a tree, and a come-along to the bent corner to a tree, and keep going till it's straight.
Or... a big sledge hammer

i have the same truck as you. i bent mine too, havent done anything to it and it still drives perfect

I would say just take it in and get it fixed right. if your tight on cash you could do the backyard method as mentioned above

Well I would do that except its the left frame horn and is preventing me from mounting my new bumper up. I think I'm gonna see if I can beat it back in to shape and if not I'll just take it in to a shop. Damn better bring the lube too...
