All,
Recently we purchased a 2004 Expedition for a secondary vehicle. It is covered by a short warranty and we have a issue I am trying to get resolved by the dealer before the warranty runs out. I will attempt to keep this long story short but...no promises
While driving the vehicle at any speed between ~20-70mph there is a "whine" type sound. How I initially described it to the dealership was similar to if you were driving in 4lo and 1st gear.
While going down the road if you bump the trans into neutral the noise goes away. Put it back in gear the sound is there.
I wrote a description of the problem and verbally told the service mgr when I dropped it off yesterday. The next day they called me with a diagnosis of "tire noise".
I disagree with their diagnosis and asked them to drive it again. It has Michelin tires that are in very good condition on it. Of note, I have had jeeps with mud tires and didn't sound anything like this. Nor any other vehicle in the past 24 years I have been driving had tires that made this alledged noise.
My question to the forum is:
1. What do you think of that diagnosis?
2. Have you ever had tires that sounded like "gears" or "bearing failure"?
3. Can anyone point me in the direction of info regarding the #9 bearing in the transmission?
4. Can anyone point me in the direction of rear axle bearing issues? Sounds that pinion bearings make when they go bad?
I did ask them to look at a TSB, I think it was 5-23-3 for the rear axle.
Thanks for any info you can provide!
I posted this on another forum, I am not discounting their information. Just seeking more on the subject.
