O4 EB Expy sounds like a howling dog!

I have a whining noise in the truck when I am going between 35 to 45 MPH. I have 43000 miles on it. I changed out the Contis with some Bridgestones thinking that was the problem. Well it is only getting worse. Once you get over 45MPH it fades away and is nice and quiet. Can anyone help with this? It is driving me crazy.
Thanks Guys.

 

might not be your tires. im on rear end number 3 no noise till 55-60 then howled like crazy. new rear end like i said number 3 no more noise

 

by the way its my wifes car. never towed a thing and rear ends galore

 

Have you checked your transmission fluid level lately?

 

Yes I did. I wasthinking maybe the u-joints or someting on the drive train. Anyone experience something like this.

 

does it still whine when you let off of the gas. my wifes expe only whined when you were on the gas and it was the ring and pinion

 

check the tires for unusual wear if they are capped replacem with new ones ,problem solved ., it happened to me .

 

When you let off the gas it does stop. Press on gas whining starts. If it my gear and pinion how much will it hit me for?

 

mine had 47k and was the third so ford customer service paid 75%, i had a bad abs sensor as well total was 480.00 they said the rear was 1200 if ford wouldnt have helped. and thats at the stealership

 

its amazing what they will do when you tell them you want to meet with the ford rep. they get alot nicer. boils down to i just griped alot
