Four weeks ago windshield wiper on rear door of my car is broke down. I don’t have enough time for visiting with this problem to the service station but I have four days of the weekends for solve this problem. Then I has armed by the famous e-catalog “AllData” which used by many servicemen. I found the necessary information about unmount rear windshield wiper on next path: Diagnosis and Repair ==> 2004 ==> Ford Truck ==> Expedition 4WD ==> V8-5.4L SOHC VIN L ==> Body and Frame ==> Doors, Hood and Trunk ==> Trunk/Liftgate ==> Trunk/Liftgate Striker ==> Service and Repair. On this page I found detailed instruction about process. I thought what the engine of wiper has broke down – this very often happens. But when I unmounted module of wiper from liftgate and tried to start the engine of wiper it worked! Well… I have tried to turn wiper shaft on unmounted module but failed. By advice of my friends from forum club www.Ford-Trucks-Club.Ru I found out next moments:
- The shaft of the wiper must turn freely
- The shaft of the wiper must dismount freely from the module after lockring remover.
I had put module into vise and tried to unmount the shaft. Only when I used much WD-40 I could pull shaft from the module. Had very many rust into channel of shaft. After clear channel and shaft I put grease like Retinax EP 2 into channel and shaft was mounted back to its place . After this process I checked work of wiper – its worked very fine!
