ok today i went out to luch rite. and on my way back to school, i fucken tagged like 4 speed bumps in a row. then after school i get in and as im pullin out of the spot i notice that my truck was severely shakin in first gear. its only in the first tho. it seems as if the truck is having a violent sezure. and im like oh fuck i prolly fucked up my drive shaft or sumthin but i dunno. from what i have told you, can you give me an idea of what it might be? remember it only does it in the first gear, after that it goes pretty smooth.
