OK, I have not had any problems with my jeep for 6 months but when I was driving to college this morning I started hearing this new off and on vibration noise comming from the back of the jeep. It only makes the noise at 65MPH + and it is not present any other time. I am also hearing a ring noise comming from the back of the jeep too but only when I am slowing down or have my foot off the gas and am coasting


It is a 1994 Jeep Grand. LTD. with 130,000 miles
