Replaced motor mounts and still no fix!
I have a 2000 Express cargo van, 2500 series with a 5.7 in it. I replaced both motor mounts after it started giving all the signs of failure (low clunking noise when stopped in gear). After I drove it with the new mounts, it ran silent for the first 5 minutes and then the familiar noise started to come back slowly :grrrrrr:. Now it runs silent the first 5 minutes everytime I drive it and the noise seems to be coming from the left side. My question now is how likely is it that the new one failed so quickly and does anyone have any advice. Honestly, I am absolutely terrified to get under it while its in gear with my wife holding the brake so any suggestions besides that would be greatly appreciated.
