hello i have a 01 ram reg cab v6 with 102k on it and lately been noticing vibration in either floor board or gas peddle when driving boubght truck with 98k off dealer installed new tires fromdiscount did tune up and allignment but now when you dive u can fell it been told different things by different mechanics brother said main bearrings mechanics said a tranny kit? exhaust?differental? but im thinking it the harmonic balancer being off but idk if any one has similar fellings or tricks to fix bought truck for 2700 and dont wanna put more into it if i dont have to unless to get it fixed

 

I have never seen a harmonic balancer just go bad. Doesn't mean it could not happen, it is just rare.

Pull upstream O2 sensor and see how it runs. Then check the Plenum sticky at the top of forum page.

 

Any particular speed that you feel the vibe?

 

everything from idle to highway speed

 

so pull o2 and let it hang while running?

 

Does it do it sitting still? If so, I suspect you have a miss...... recheck tune-up parts.

 

If you had a 5.9 I would say its just the engine, but since you have a V6 it's probably something else.

Could be a miss or just old parts.

 

Start with HeyYou suggestion's

Other things to check are

tranny mount
motor mounts
cross-joints
pinion bearing outer
E brake cables, make sure they are releasing all the way
check for grabby rear brakes
Axle bearings
brake drums out of round

 

yes at idle to
