2003 Rear axle whine

2003 XLT 24K miles almost out of warranty first of August.

Calcification on rear axle noise?

I think my explorer in getting the famous rear end whine. At speeds
between 40 and 65 there is a loud whining sound BUT when I take my foot off
of the gas the whine sound quits. Is this what everyone has been talking
about or something else?

Thanks
Richard Grimes

Spell check and are not friends. I have no clue what Calcification on rear
axle noise is. It should read something like clarification.

Nope, you've got the whine

When you take your foot off the gas you take the load off the bearings

Better hurry !!!!!!!!!!!

REAR AXLE NOISE REPAIR\

FORD:
1997-2005 Expedition, F-150
2002-2005 Explorer
LINCOLN:
1998-2005 Navigator
2003-2005 Aviator
MERCURY:
2002-2005 Mountaineer

This article supersedes TSB 05-12-6 to update the Service Kit and
Service Procedure information.

ISSUE

Some vehicles may exhibit an axle whine or hum during acceleration,
deceleration and/or cruise.

ACTION
An axle repair kit has been developed which incorporates most parts
required for a comprehensive axle repair. The kit should be used
instead of installing a complete axle assembly to repair an axle
whine/hum. Replace Ring and Pinion with Axle Kit and Components.

NOTE REFER TO THE "DIFFERENTIAL RING AND PINION" IN-VEHICLE REPAIR
PROCEDURE IN THE ONLINE WORKSHOP MANUAL SECTION 205-00, FOR THE LATEST
AXLE DIAGNOSIS AND REPAIR PROCEDURES.

NOTE FOR 1999 AND PRIOR MODEL YEAR VEHICLES, USE THE 2000 MODEL YEAR
WORKSHOP MANUAL.

NOTE WHEN SERVICING THE REAR AXLE ON ANY 2002-2004 F-150, EXPEDITION,
NAVIGATOR, EXPLORER OR MOUNTAINEER BUILT BEFORE 3/30/2004, IF FLUID
REPLACEMENT IS REQUIRED, REPLACE THE ORIGINAL FUEL EFFICIENT HIGH
PERFORMANCE (FEHP) SAE 75W-90 REAR AXLE LUBRICANT WITH SAE 75W-140 HIGH
PERFORMANCE SYNTHETIC REAR AXLE LUBRICANT. WHEN THE FLUID TYPE IS
CHANGED, REPLACE THE CURRENT "FEHP" METAL TAG WITH A NEW "75W-140" TAG
(F3TZ-4121-AA). IN ADDITION, REMOVE OR BLOCK-OUT THE FEHP REFERENCE ON
THE MULTI-COLORED LABEL LOCATED ON THE RIGHT SIDE AXLE TUBE. IF THE
AXLE IS A LIMITED-SLIP MODEL, USE XL3 ADDITIVE FRICTION MODIFIER IN THE
QUANTITY RECOMMENDED BY THE WORKSHOP MANUAL.

KIT ORDERING: REFER TO THE VEHICLE AXLE TAG FOR AXLE RATIO

I called the local Ford store and they said it sounds like the bearings to
them. They will test drive to confirm the problem then order the parts.
I will let everyone know how it all comes out!

The local FORD store (where I bought the last 3 vehicles from) asked me to
come in Saturday morning at 7:30 so the service guy could verify the
problem. They feed me a sausage biscuit and had me on my way by 8:00.
They are ordering the bearing kit or whatever to install as soon as it
comes in. Looks good so far.......

This is an inherent design problem with many Fords. I have a 2002 F-150 with
the same thing. Took it to the dealer, under warranty, who inspected it and
said everything was OK. But it still whines 40K later. My wife's 2004 Sport
Trac has the same problem. This is one reason why Ford is loosing market
share to Toyota and everyone else. They won't do what they need to do to put
these kind of problems to bed.
I don't believe it has anything to do with the bearings. I believe it has to
do with an improper meshing of the ring and pinion gears. My truck now has
57K on it and the noise is the same.
