1992 gmc sierra started shaking when I was driving.. Any help?
I was driving home today I was shifting to
5th gear and my truck started to shake!
I've been feeling a little vibration under my
drivers seat and went underneath to see
what was wrong and I noticed that there is
a drive line or shaft (whatever it's called)
going to the front axel and it is loose. But
all the bolts were tight.. I don't know
what's wrong! Does anyone have any advice?
