I've noticed that there are a few posts here about a whining noise that
seems to come from the rear differential. My 2002 XLT 4.0 seems to have
this same problem that you can only hear under acceleration around 45-55
I have seen on the NHTSA website that there are some TSB's about the
problem, but ALLDATA's website doesn't list them as available to get the
whole content. Does anyone out there know about the bulletins? I think the
most relevant one would be #17736. I would appreciate any information
someone could share.
The reason you don't see any TSB's on ALLDATA is there have been none issued on
this topic. The #17736 you refer to is a special service message, and it
concerns rear axle noise in 2002-04 Explorer 4dr and 2003-04 Aviators with 3.73
axle. It instructs the dealer to evaluate the intensity of the whine and
replace the entire rear axle assembly if the noise level is unacceptable.
Effective date of this message is 4/23/04.
I have been reading posts about this problem for some time. Last
week, I rented a 2004 XLT with 19,000 miles. The rear axle whine was
totally unacceptable at around 55 mph. Most posts say that Ford has
been unable to fix the problem, meaning that it is a design problem.
I am in the market for a replacement for my '99 EB, but will not buy a
new Explorer if the vehicle is likely to develop an unfixable problem
as annoying as this.

Additionally, if you purchased your car from the vendor with the lowest
price, you will very likely receive inferior service. This will drive you to
another dealer who WILL offer inferior service because you didn't purchase
your car from him/her.
There is an SSM that covers the rear axle whine... part of the procedure is
a revised fluid level spec which will have KwikeeLoob draining about $20
worth of synthetic gear oil into a bucket and saying they "fixed" a
Jim - Thanks for the information. I bought a new 05 Limited
yesterday, for delivery in early September (scheduled for build 8/23).
So, my '99 will go to our son and his '92 will be sold.

This is a bunk statement. Dealers LOVE warranty work. Ford pays them based
on how long the job should take according to them. 90% of the time, the
dealership can perform the job in much less time and they make even more
For example, if Ford decides a specific repair should take 2 hours to perform,
the dealership is reimbursed the hourly rate of 2 hours. If the dealership
was able to perform the repair in 1 hour, they still get paid for 2. It's
been this way for years - and not just with Ford.
I should clarify that dealerships love warranty work that falls under the 3/36
factory warranty. Extended warranty work is the burdon of the dealership that
sold it to you.
Add the '02 Mountaineer to the list.
My Mountaineer (35K miles) had the whining noise coming from the rear
The Mercury dealer fixed it by replacing the "2 pitted rear axle
bearings" ($680 job covered under factory warranty). The new parts are
for another 12Mths/12K miles ... Now my SUV runs smooth&quiet.

They have a new rear axle on order for me and say they have replaced about
12 so far.
The dealer says Ford has never told them what the cause of the problem is.
This vehicle was built in Jan of 04.

Mine too developed that problem. Brand new 2004 Ford Explorer XLT limited
slip axel that came with the class III tow package. Developed whine at
4800 miles. Dealer is replacing the differential and said to come back
when the parts arrive. It sounds like slack or wear in the rear end. Sound
pitch starts low at 35 and gets higher pitch until it blends in with
freeway noises and normal tire noise at 75MPH. When you take the
acceleration off and almost coast, the whine sounds louder, especially mid
speeds between 40 and 55. I am not happy with the car because of this.
Sounds like Ford knows about this problem and is hiding it. The immediate
replacement under warrenty probably wont fix it for very long. Is there a
permanent fix? firstname.lastname@example.org
Just dropped off my Explorer at the dealership and they called to say that
they are replacing the rear axle because that is what Ford instructed them
to do. Hopefully I will get an explanation when I pick it up.
I have an '04 Eddie Bauer w/3.73 Limited Slip rear end. Purchased it
last April. It now has 5300 miles. Last week I started to notice a
slight rear end whine. Took it into the dealer today-took a tech for a
drive-he heard the sound. They immediately orderd a complete rear
axle. I'll report back after it's installed and I put another 5 or
10 k on it.
At least I'm getting GOOD service!!!!!
They replaced the rear in my 02 Explorer TWICE. The noise was still there.
They just can't fix the damn thing. I had an appointment with a Ford
engineer at the dealer after that and he never showed up. I give up. Ford
wins. I'm getting rid of it. This is one miserable mess of an experience
with a car.
