We recently purchased a 2003 Eddie Bauer Explorer.

Whilst driving with speed control engaged, It felt as though the brakes were
being applied.

I also subscribe to an Expedition news group and the following TSB was
posted.

Does Ford pay for the TSB repair or do I have to stand it.???

Ride safe

line coverage.

ISSUE

Some 2003-2005 Expedition/Navigator, 2004-2005 F-150 vehicles equipped with
a 9.75" or 8.8" limited slip rear axle, and 2002-2005 Explorer 4dr,
Mountaineer, Crown Victoria, Grand Marquis, Town Car, and Mustang vehicles
equipped with 8.8" limited slip rear axle, may exhibit a chatter, shudder, a
binding sensation, or a vibration during low speed turns. On 4x4 vehicles,
the sensation may appear to be originating from the front axle or the
steering gear.

ACTION

First verify the condition. On 4x4 trucks ensure that the vehicle is in 2WD,
to isolate the rear axle. On all vehicles, turn the wheel fully right (or
fully left) and then accelerate the vehicle. If the condition is verified to
be in the rear axle, replace the limited slip clutch pack.

SERVICE PROCEDURE

CAUTION INSTRUCT THE CUSTOMER NOT TO TOW WITH THE VEHICLE FOR 500 MILES
AFTER THIS REPAIR, TO ALLOW THE AXLE TO BREAK-IN PROPERLY.

Order and install the appropriate clutch pack, follow the installation
instruction sheet included in the service kit.

^ 3L1Z-4947-AB (9.75" limited slip)

^ 3L1Z-4947-BC (8.8" limited slip)

NOTE INSTALLING A CLUTCH PACK INTO AN INDEPENDENT REAR SUSPENSION (IRS) AXLE
IS DIFFERENT FROM INSTALLING A CLUTCH PACK INTO A SOLID-BEAM AXLE. BE SURE
TO FOLLOW THE INSTALLATION INSTRUCTION SHEET INCLUDED IN THE SERVICE KIT.

INSTALLATION TIPS

^ The clutch packs in this service kit DO NOT need to be shimmed. The clutch
pack contains a pre-measured shim.

^ Be sure to install NEW circlips and halfshaft/wheel end nuts on IRS rear
axle (not included in the service kit).

^ Soak the new clutch packs in Friction Modifier XL-3 (NOT XL-7) for fifteen
(15) minutes prior to installation.

^ For IRS axle, Halfshaft Seal Protector 205-506 (included in the 2002
Explorer/Mountaineer Essential Tool Kit) must be used when removing the
halfshafts to protect against seal damage, which may result in leaks.

^ Refill axles with 4 oz. Friction Modifier (XL-3) and the necessary amount
of Rear Axle Lubricant XY-75W140-QL, regardless of the axle lubricant system
originally used in the axle. Fill to capacity recommended in the Workshop
Manual.

NOTE AXLE FLUID REQUIREMENTS HAVE BEEN CHANGED. ALL VEHICLES BEING REPAIRED
BY THIS TSB MUST HAVE REAR AXLE LUBE XY-75W140-QL INSTALLED, IN PLACE OF
XY75W90-QFEHP. AS PART OF THIS REPAIR, CHECK AND REPLACE IF NECESSARY THE
CURRENT XY-75W90-Q"FEHP" METAL TAG, WITH A NEW 75W140 TAG (F3TZ-4121-AA).
ADDITIONALLY, REMOVE THE MULTI-COLORED LABEL WHICH IS LOCATED ON THE RIGHT
SIDE AXLE TUBE, OR BLOCK OUT ANY/ALL "FEHP" OR "75W90" REFERENCES ON THE
LABEL.
