This is my first post here so I apologize if my formatting or wording is off. Ive used this site quite a bit in the past to solve minor issue with the H3. I'm going to do my best to describe the sound that I just cannot seem to diagnose and its really really bothering me lol. When I'm driving and already up to speed I get a weird noise/ Vibration AFTER I either add more gas to speed up or just to maintain speed... So in short this vibration happens after i speed up while already moving.. Kinda hard to describe. If anyone wants to pick my brain to maybe get a better idea please feel free.

a couple of things.

1. Its a red 2007 H3 with 62,000 miles on it.
2. I'm going to check the transmission fluid today
3. My tires were recently balanced
4. Oil and filter just changed
5. Have not checked park plugs yet

I really appreciate any help or insight as I'm going to go underneath the truck this weekend to try and figure this out. Thanks!

 

not sure how to edit the post.... The vibration does go away after a few seconds! may or may not change anyone's diagnosis. Thanks
