thumps while driving on the freeway

so every once n a while i hear thumps from underneath my truck, like a rock hit the frame but WRONG i look back and theres nothing. today it happened but on the left front tire...which i also screwed up i think i messed the alignment up because if im going straight in order to keep going straight i have to turn the steering wheel slightly to the right. anyone have a solution to the thumps from udner the truck?

on the bright side i have some pics from saturday

 

wow idk what that is but it sounds crappy

 

its the tires not the suspension or anything i might have bent when off roading?

 

x2

 

haha c'mon stevooo did ya really know that or just wanted to add to that post count LOL!

 

Haha, BUSTED lol... I kinda knew what it meant

 

Does it seem to matter what speed you are going when you hear the thumps? I recently made a thread about noises from the left front around 40-60 mph The local dealership has no clue. It sounds like we have the same issue or something similar.

 

shit going 65-80 mph...i gotta wait till friday to have the truck looked at since im working at of town and im staying at a hotel...i may have pushed the truck alittle harder than usual in the pics all those trails are hills to climb some 2wd friendly some are really tough and there was alot of dips...its a playground for offroading

 

I did that too!
But I was the jackass...
And it was a Tahoe...

What a rush!!!
I straightened it out and kept driving never dipped below 45.
How about you?

 

I've noticed the sound on my '09 a couple times. Like you said, it sounds like a rock or road debris hit the underside. Usually it sounds like it's coming from the rear passenger side.... My truck drives strait, and has never been off the pavement.
