ok i sled pulled down in north carolina and now i have a vibration in the rear. i know its not the front bc i drove around in ricer mode to make sure. but at around 40-55 it shakes. me and jake put her on stands last night and my rear yolk out of the axle looks to be bent? its not turning true how could i bend this on a pretty much stock truck? anyone ever heard of this? it does have ne u joints and carrier bearing. any info would be great i plan on taken it to a driveline shop here monday.
