[TexasRTR78]

Ok, I FINALLY got my H3 to the Lubbock dealership yesterday. The Hummer service guy that I usually deal with was there this time (he was not there the last time I took it in for this popping noise problem). I explained to him what the problem was and he said he would like to drive it so that he could hear and feel the problem. When we got back I told him that I had been explaining my problem on this forum and that several people said that it was the body mounts and I asked him to "PLEASE" have them checked just to be sure. He gave me a loaner car and I left...around noon he called and told me that "IT WAS THE FRONT BODY MOUNTS"!!! He mentioned something about "lubing them but the problem would just come back again, so we have ordered them and are going to replace them". My 2 middle AC/Heater vents were also broke so he is going to replace those as well. He said that it would probably take a couple of days to get the parts here and installed so I am driving around a white Impala (yeah, wish I could have got an H3 instead) until then. I will post the rest of the results as soon as I get them.
