i did not check the driveshaft for movement. All i did was take the video. So when i dig deeper into this.....
1st- put in nuetral and rock driveshaft back and forth
2nd- pull wheels and drums and re test running in gear
3rd- remove diff cover and check to see if anything is broken
When i bought the car in early october, there were no noises like this at all like it should be. This started out as a very slight noise and has progressed to how you hear it in the video. I have only driven the car about 300 miles since i bought it.
As far as the noise goes and putting in nuetral while coasting, the noise goes away. Revving in nuetral while coasting the noise is not there. Put it back in drive, and accelerate, the noise comes back. while its making the noise, if i accelerate a little slower, the noise getting quieter. The harder im on the gas, the fast the noise gets and the louder it gets. It is def coming from the back of the car though. Without more testing, im pretty perplexed as to what it could be. Im at work now so i will try to take a look this evening after im done coaching my teams basketball practice. Sorry to keep you guys waiting!
