ISSUE
Some 2009-2012 Escape, 2009-2011 Mariner and 2010-2012 Fusion, 2010-2011 Milan vehicles equipped with a 6F35 automatic transmission may exhibit a fluid leak from the left hand (LH) halfshaft seal. This may be due to seal and/or bushing wear caused by the halfshaft surface finish.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
A service kit is now available for Escape, Mariner, Fusion and Milan which have all the parts needed to make the repair including the bushing and seal.
Escape And Mariner
The Escape and Mariner kit includes the inboard constant velocity (CV) joint housing, and eliminates the need for halfshaft assembly replacement. The kit does include additional parts (halfshaft boot and small clamp) that are not required for this repair.
1. Replace the LH halfshaft seal. Refer to WSM Section 307-01. When the halfshaft seal is removed, visually inspect the transaxle case bushing for wear.
a. If bushing is visually worn, replace the bushing in the transaxle case. Refer to WSM, Section 307-01.
b. If bushing is not visually worn; clean the area behind the halfshaft seal before installing the new seal.
2. Clamp the LH halfshaft in a soft-jawed vise. Use care not to damage the boot or component damage may occur.
3. Remove and discard the one (1) large inboard CV boot clamp. (Figure 1)
4. Remove the inboard CV joint housing and discard. (Figure 2)
5. Push the boot back and remove all the grease from the boot.
6. Install half of the packet of grease (supplied with kit) into the new CV joint housing. Inject the other half of grease into the boot on the CV tripod joint.
7. Install the new inboard CV joint housing on the CV tripod joint and new large inboard CV boot clamp.
8. Insert a small, flat-blade screwdriver under the boot seat to allow the air to escape. Slide the tripod joint in as far as it will go, then pull it out 20 mm (0.787 in). Remove the screwdriver.
9. Using special service tool 205-343 (constant velocity joint boot clamp installer) or equivalent, install the new CV boot clamp. (Figure 3)
Fusion And Milan
The Fusion and Milan kit includes the halfshaft assembly.
1. Replace the LH halfshaft and seal. Refer to WSM, Section 307-01. When the halfshaft seal is removed, visually inspect the transaxle case bushing for wear.

b. If bushing is not visually worn; clean the area behind the halfshaft seal before installing the new seal.
