could need your wheel's speed balanced or a belt in the tire may have shifted

 

i was also thinking thhe same thing that i might have to get the wheel balanced. sorry i don't know wat belt u are takling about?

 

Does it seem to happen more often when accelerating and go away if you let off the gas?

If so, you have a failing CV joint.

 

yes, that is quite right, it does seems to happen more often when accelerating and goes away when i let off the gas

 

Is it just a noise, or are you feeling it in your steering wheel?

 

yes it is just a noise but the steering wheel is fine. i am not quite sure if i felt it in the steering wheel, the vibration only comes on the right side

 

the tire's have steel belts in them and some time's they break causing the tire to change shape. which will cause vibration.

 

i think u mightbe right but can iget them fixed and do i have to go to a mechanic to get it checked?

 

i've experienced a failing rear axle bearing and an out of balance wheel... both will have harmonic vibration at certain highway speeds...

but now on my legend i have the same issue at the same speeds due to some bia cuttin me off and me having to bump a curb... leads me to wonder about a bushing or the cv's.

 

You might've thrown the wheel out of balance or worse, out of round, when hitting the curb?

 

that's what i'm hoping... but there's a chance that something got bent and only at certain speed will the loosness wobble... cuz it'll happen at lower speeds too but only with i'm at a 5% acceleration... right after coasting.

 

i also want to share one more thing. when i installed the 3.5, then i noticed that the car noise started to occur. then i installed the full expansion kit. later on, the vibration started to occur more. i spoke to the mechanic and he told me its a new kit and it may go away after a while, but the vibration started to occur more frequently. i bought the kit on ebay.....is the ebay kit okay....l

 

second on those axles..get them checked

 

had the same problem, tires looked new but needed balanced, hope thats all it is

 

My car did the same thing...it was the CV axles.

 

I went through this recently and cured it with new axles/CV.. This was after engine mounts,tire balance.Be certain that you do not use REBUILT.I went through 2 sets and after arguing with mechanic and parts dept. for 3-4 weeks demanded NAPA OEM or Raxles.com be installed.Runs like new,no vibration..Save yourself some grief and money.
As an old tire guy,you can have the tire shop run a diagnostic on the tire/rim and they will be able to tell you what % of your problem is tire VS rim.
