Gear problem

i have 4.10s in my car and i havent had them that long. My car is an automatic if that has anything to do with the problem.

When im on the highway cruising at 70 they make this whistle...whistle...whistle sound and it gets faster as i accelerate. But if i am below 70 there is no whistle sound. I know 4.10s ten to whistle but i dont think this much. They did whistle a little bit when i first got them. I dont know if they have a broken tooth/teeth, not installed to well, need to change fluid or what. Anybody have any idea to what might be the problem?

is it a constant whistle or does it come and go?

It is constant. It only happens when i go 70+ though. It doesnt really do it under 70.

That makes me feel a little better. It has gotten really annoying though. I dont think anyone wanting to buy it will like that haha.

How long have they been in? brand? I have 0 noise out of my 4.10s

haha thats what i do. I always wonder if the people next to me can hear it

The newer body style cars have a tendency to transmit noise. It has a lot to do with how the reared is mounted in the car. Does the noise subside on decell?

Yes, the noise completely goes away when i deccelerate.
