High Pitched Whining Above 20 MPH
John Palmer
the car has been sitting outside very often I get a load whining noise that
starts at about 20 mph. It can be characterized as a squelling, high pitched
noise that increases in loudness with speed. It is not the serpentine belt.
Almost sounds like it's coming from the transmission. It stops making the
noise below 20 mph. Any thoughts on the source. I want to take back to
dealer but can't yet isolate the exact source. Thanks.

I have a 98 with a 5-speed auto and a 4.0 SOHC engine. I also have a whinning
or whistleing sound while driving, when the truck is cold AND when the outside
temperature is cold (<30F). The whistleing sound starts as soon as the vehicle
moves and continues up to about 35-40mph, above this speed I do not notice it.
At first I thought it was the power steering, but the noise does not change if
you steer from side to side. It also does not change if you slip the
transmission into nuetral and change motor RPM(while driving). This leads me to
beleive it is in the transmission or drivetrain, because is is speed dependent.
I took it to the dealer, but that day it was 65F, go figure!
Please let me know what you find out, I am dieing to know.

same exact problem here...but goes-away after
a few minutes of driving...suspect it has something
to do with thickening of lubricant in drivetrain.just
drive slowly for the first few miles and you'll be ok.
extra viscosity is more important in the summer
months. very hard to find a lubricant to cover all
temperature ranges satisfactorily

been discovering what I've been complaining about here in Alaska since
October. The high pitched squeal we've been hearing from both our '98 4x4
Explorer automatic 4.0 and '98 Explorer 5 speed manual 4.0 seems to be
coming from the front end - almost sounds like a bearing squeal. I took
both into the dealer and they said all the grease had leaked out of the
axles so they repacked the bearings and thought all would be fine. Forget
it as they started squealing within a week after we got them home.
The dealership can't figure out the problem so we've driven them this way
hoping others would discover the same problem thus causing Ford to
determine the cause. Whenever it is squealing, we notice it only does it
for the first 10 minutes of driving and then goes away (almost like
something has to warm up first). We just hope it isn't doing any damage.
We too would like to know if there's an answer/solution to the problem out
there....

At first, I thought this was another symptom of the 4 speed and 5 speed auto
"whistling" problem that's TSB'ed at NHTSA.
But I went to a Ford dealer and made them print out the TSB (which they were
extremely unhappy about doing, for reasons that completely mystify me), and
the TSB talks about a main control plate that has an incorrectly sized
orifice.
So, I have that problem (as I bet all of you with '97 or '98 auto trannys
do), but this cold weather drivetrain squeal seems like another problem.
I can't get mine to do it all the time (or maybe I haven't discovered the
pattern yet), so I am going to wait until a) it gets louder and repeatable
or b) I am within a few Ks of warranty expiration.

rusted inside of my brake rotors catching the brake pad. They said I would
need new rotors and pads to 'fix' the problem...at my expense! This is my
first Ford and I'm really not impressed.

Matmanscag
with 9000 mostly highway miles that seemed impossible.Have to bring my 98 back
anyway rear wiper wont go. ALL THAT MONEY FOR A NEW TRUCK,YOU THINK THEY WOULD
BUILD A QUALITY PRODUCT!!!!

reluctance to rotate the tires.. I didn't like them anyways, and was
planning to replace them for Michlin's (sp?). When I finally go the new
tires, all the road noise and whining sounds went too. If it is a problem
with rusted brake roters, then ford should pay for that to be fixed if the
cause of the rusting is abnormal. Take the argument up with the owner of
the dealership.

intermittent? Mine is intermittent, and I can most often hear it when I'm
driving next to a median wall (the sound probably bounces off the median wall
back to me). I considered bringing this in, but the dealer would probably
just end up keeping my car for 2 days and then telling me they couldn't find
anything.

make a long story short, I was told the problem is in the upper (?) intake
manifold caused by the new composite material being used in 1996 models.
All I know is that it shows up as a whistling sound above about 30 mph under
light to moderate acceleration.
I'm interested in any TSB numbers anyone has available.

lessens in a few blocks and I've only noticed it since it got cold. I have
4,000 miles on the vehicle.
I had a 94 Ranger with 4-wheel drive and it did NOT do the same thing - it
only had two-wheel disk brakes and drums in the rear, and it had a 4-speed
auto and not the 5-speed auto in my current Explorer.
It goes in to the dealer tomorrow to see what they can find.

Explorer (4-wheel drive with 4,000 miles) in to the dealer for the same
problem and they have order parts, per Ford's instructions.
The dealer called the Ford "Hot Line", they are aware of the noise and told
them to order the following parts (the quantity of two is probably to take
care of both axles on the front of the vehicle):
(Qty 2) FMC # F57Z 1190 AA Seal, Asy - Oil
(Qty 2) FMC # F57Z 3K070 AA Shield - Dust
There is no Technical Service Bulletin on the problem. My experience of the
problem is a squeal as I first drive on a cold morning until things warm up.
It is not related to engine or brakes and it is only when the vehicle is in
motion (around 20 MPH) - it goes away with increased/decreased speed or
temperature.
