While driving the car you can hear a noise almost like a bent rim or flat spot but when you turn back and forth it goes away when you turn hard left....

I checked bearings rims tires etc...I even threw another set of rims off my track car on it and its still doing the same thing...

Now my question is are these driveshafts balanced from factory with weights ? Maybe a bad u joint vibrated the weight off, I'm F'n lost here.

I found another driveshaft for 150 out of a z with 40k miles. Anyone have any input ?

 

Have you checked your steering rack&bushings?

 

I have no idea what a bent rim sounds like, but I don't see why it would go away when you turn the wheel back and forth. If you changed rims and still have the noise, it's almost certainly not the wheels.

I also don't see why you'd want to replace the driveshaft when you suspect the noise might be caused by a bad wheel. The frequency of the noise would be very different for something related to the driveshaft vs something related to the wheels.

In short, you haven't described the symptoms well enough for someone to make a meaningful diagnosis. Can you make a video with the sound?

 

Sorry if I wasn't clear but the noise is an oscillating noise resonating from what I think is the front right. As I stated it sounds like a bent rim but is clearly not since everything checks out and it still does the same thing even with my fno1rcs. I'm going to pull the bearing out tomorrow since I'm convinced its gotta be bad. I'll keep you guys posted and thanks for the interest.

 

Maybe your rotors are warped, have you done any hard or high speed braking and then drive thru some water?

 

Could be a bad wheel bearing.

 

Hey guys thanks for all your input, it ended up being the front wheel bearing...Seemed to pass all the tests but we switched it out anyway and it's gone !

Thanks again

 

That's good, and thanks for letting us know what the problem was.
