They changed my u joints a couple months ago ,I was noticing a vibration I brought it to a mechanic friend of mine he noticed the vibration and looked under my truck the center support was bent and hanging by 2 threads one bolt the other was gone ,he said if I drove it anymore it would come off and drives shaft would rupture the gas tank and explode, that's what keeps them rolling did by not tighting the bolts,i would not be here if I didnt notice it ,avoid them,
