I found this posted on the Chrysler site today. The release date on the recall is 4/2010. Here is some of what is on the recall notice-
2002 - 2003 (KJ) Jeep® Liberty
NOTE: This recall applies only to the above vehicles built from May 1, 2002
through September 30, 2002 (MDH 050100 through 093023).
IMPORTANT: Only the above vehicles sold or currently registered in “salt belt”
states (where large amounts of road salt are used for snow and ice removal) are
involved. See “Owner Notification and Service Scheduling” section for a list of
salt belt states.
The front suspension upper control arm ball joints on about 42,000 of the above
vehicles may experience a loss of lubricant that can lead to corrosion, accelerated
wear, and possibly separation while driving. A separated upper ball joint while
driving could cause a crash without warning.
The front suspension right and left side upper control arms must be replaced.
