This answer was rated:

2003 ford taurus humming " rotational noise" starts at about 20mph on up gets louder on left weave at speed replaced right front wheel bearing new pads and rotors on the front. cv boots intact joints dont appear to have any play . the right inner cv joint has some play up and down in the trans however the seal is not leaking help please
Hello my name isXXXXX have you jacked up the front end and started vehicle and spun the tires trying to recreate the noise?
Customer: replied 7 years ago.
yes noise is less
I would use a stethoscope to determine if the noise is on the left or right side, or possibly in the transmission, using the stethoscope you will be able to tell quickly which component is noisy, these can be purchased a local parts store, any more questions just ask. Thanks Steve W

i believe the bearing in the trans to the right inner cv joint is worn . Is this a common problem on the taurus and can the bearing be replaced without disassembling the trans
No, this is not a common concern for these vehicles and the bearing is actually a bushing, I have never replaced one of these. The transmission must be completely disassembled, this is the one of the first parts to go in the transmission.

is it possible that the cv joint end that slides in the bushing is worn ? there is more "play" in the right side then the left and thats where the noise apears to be coming from. how much play is normal

There will be play in the cv axles where it enters the transmission, some movement is normal, if have alot of movement then you have probably found your problem. Is there fluid leaking there also?

Customer: replied 7 years ago.
no fluid leak thats the confusing part just more play on the right than the left car has 123,000 miles on it and i hate to just keep replacing stuff at random i've seen alot of tranny problems with the taurus on the net however it runs and shifts fine . it sounds exactly like a bad wheel bearing
Does it sound loud at the transmission on the right side with a stethoscope on it?
Customer: replied 7 years ago.
yes but not sure if noise is tranferring from cv joint
If your transmission is due for service, it might not be a bad idea and drop the transmission pan and see if there is any metal coming from a planetary or the differential, noisy planetaries sound like bad wheel bearings also.
