i have a 04 v8 4x4 4runner that has a intermintent vibration that feels like it is coming from the front end but it only does it when accelerating and i can feel it from the pedal. if i take my foot off the pedal it stops. it has 104,00 miles. im thinking about haveing the transmission serviced and im going to change the front diff fluid and transfer case fluid. if i get the trans serviced should i do a flush or a fluid and filter change. the dealer said i should do a flush but i dont have alot of confidence in them. any help is appreciated.

 

Ive also got an 04 4wd v8 its at 93,xxx and i had the same symptoms, i changed the tranny fluid and filter as well as the fluids in the front and rear diffs and no luck, it eventually got unbareable to the point where i was turning heads just from the noise it was making.. turns out it was a wheel bearing that took a ˟˟˟˟, the bearing it self was almost $200

 

I did a drain and fill on the tyranny and it solved the problem
