Ford F150 with 9.75 main cause of differential replacement

Post by dmatchett » Wed Mar 02, 2016 10:53 am

Over the years we have seen a large increase in differential work for Ford F150 5.4L 9.75 12 bolt
rear differentials and we have been recommending that shops doing any kind of service work include
looking at the rear differential and tie the vent tube up, currently Ford's design has it laying in the
trough allowing water to seep into the differential, water contamination is the number one cause of
these differentials going bad.
