01 elantra vibration/noise

okay, after changing my cv axles last weekend,(thanks for your guidance on
that one hyundaitech!!) my elantra has developed an interesting new noise.

as I accelerate through the gears, I've noticed in the range of 3100 to 3300
rpm (manual trans) that I get a weird noise/vibration.like a loud BVVVT
it's only when accelerating, in gear. if sitting still and revving the
engine, there is no noise. when decelerating there is no noise. the worst
part is that it happens right at about 75 to 80 mph in 5th gear, which is
where i set the cruise when travelling on the interstate. (the speed limit
is 70 here) and the vibration will actually be transmitted through the body
of the car. I'm perplexed.

Any help is much appreciated

 

Obey the law and you won't have a problem.

which solves the problem in 5th gear, but what about the other 4? ;-)

 

Go back and check your axle nuts and be sure they're tight. Other than
that, I can think of little reason why the noise/vibration would be
related.

 

i made sure they were torqued properly when I installed them.

the noise hasn't gotten worse, or changed at all. it's odd, but I guess
I'll live with it until something comes of it.
