After market motor mounts
I changed my old motor mounts after dealing with the annoying vibration for a couple of months. I purchased some after market mounts(now I know was a terrible idea) that had good reviews. Anyways I put the new mounts on started the envoy up and it idled smooth again so I took it for a little drive and it ran great. When I got home I shut it off and noticed it still shook a little like it was doing with the old mounts anyways a few days went by we drove it around town and to work and the vibration when turning off got a little worse so I had my wife shut it off one time while I watched the motor mounts and the passenger side mount almost looked as if the stud going through the mount unattached from the mount it that’s even possible. The way it shook the actual mount didn’t seem to move but the stud and engine did. Am I crazy or is this the product of not buying ac delco mounts?
