I have an 05 SR5 that has started a wierd vibration. I only experience it when I am in drive and at a complete stop. I had it at the dealer for an oil change, tire rotation, etc this morning and when I went to pick it up they said that they didn't detect or feel the vibration. That didn't really satisfy me so I asked to have someone ride with me.....sure enough it happened and the service tech felt it. While he was reluctant to take it back because they thought it was the difference between summer and winter blend gas I left it there and told them to let me know what they found. If anyone has any input on this or experienced it themselves please let me know. I will likewise keep everyone posted on what I find out.
