Hey guys relatively new here. I have a few problems that just arose, and I would like your guys' opinion. I have a '93 and it just recently started shaking at about 30 mph only when I am accelerating, when I let off the gas and coast it rides normal. It feels like its the whole ass end shaking, but I have no Idea what this could be. The wheels are balanced, the ubolts are tight, and the driveshaft doesn't look to be dented. Any help would be great. Also there is a weird knocking when my engine turns over. It is kinda loud and knocks about ten time in about 2 to 3 seconds then goes away, there is no noise when it idles or accelerates. Thanks guys.
