ISSUE
Some 1999 Crown Victoria Police vehicles may exhibit a vibration and/or transmission fluid leak from the extension housing seal area. This may be due
to extended high speed operation which may cause the extension housing bushing or seal to walk/spin out due to excessive driveshaft flexing.
ACTION
Inspect the extension housing bushing. If the extension bushing/seal is spun and/or has walked out, replace the extension housing assembly and gasket.
Verify the vehicle has "GNX" level rear springs and that the revised Metal Matrix Composite (MMC) driveshaft is installed. The revised driveshaft does
not flex as much during sustained high speed operation and should reduce the possibility of fluid leaks. Refer to the following Service Procedure for
details
SERVICE PROCEDURE
1.
Raise the vehicle on a hoist and inspect the transmission extension bushing for damage and transmission fluid leaking from the extension housing
seal area. In addition, verify that the vehicle is equipped with the MMC driveshaft and the latest level coil springs (GNX). The MMC driveshaft
can be identified by the pink/green stripes around the driveshaft tube. The aluminum driveshaft will have pink/blue/orange stripes.
2.
If the bushing is found to be damaged, remove the driveshaft and transmission extension housing per the appropriate Workshop Manual Section.
3.
Replace the Extension Housing Assembly (F5UZ-7A039-A) and Extension Housing Gasket (F7AZ-7086-A) following the procedure outlined in
the Workshop Manual.
4.
If the vehicle is equipped with an aluminum driveshaft, the driveshaft must be replaced with the revised MMC Driveshaft (XW7Z-4602-AA).
