Thanks for the help guys. The shaking started back in December of 2006 when I drove from El Paso to Houston. It was a little shaking that did not get much of my attention. In January of this year I drove from El Paso to Ft. Sill, Oklahoma and the shaking did not get any worse.(While at Ft. Sill I drove less than 500 miles total in and around town) Then in February I took a short trip from Ft. Sill to Memphis then to Ft. Leonard Wood; all in a weekend. On my way to Ft. Leonard Wood the shaking got worse. Currently the shaking is at its worst point right know. I have driven very little around Ft. Leonard Wood (less than 30 miles per week, I car pool frequently.)

The Montero shakes more when I reach 45 mph and accelerate. If I'm going down hill and the Montero is on neutral it shakes just as much, above 45 mph. Hope this information helps. I just want to make it home safely and spend my money wisely in fixing this problem. Thanks in advance
