Vibration on low gears
#1

Thanks for your response LxMan1! I recently had a tune up done a few months ago, so the plugs should be good. In reviewing my paperwork from the shop at the time of the tune-up, they noted that there was a mis-fire on #2 at that point. I wonder if there is something wrong with the housing assembly.

I would start by checking the plugs and coils. When a coil or two goes bad it can cause a serious vibration that is typically felt at low loads such as cruising at freeway speeds. I have seen a truck with two bad coils feel like it was going to rattle itself apart at cruising speeds. I have heard people incorrectly diagnose this as water in the fuel tank. After that I would probably move toward the rear diff and the tranny and drivetrain components such as u joints.
