I encountered an interesting problem with Fel-Pro’s rear main seal, the brown one in this picture. Compared with the black Motorcraft seal I bought from South Bay Ford, the Fel-Pro seal has an extra lip that faces the transmission, and it prevented the seal from fitting over my Ford- recommended OTC rear seal installation tool, so I had to buy and install the Motorcraft seal instead. We recommend installing the crank seals with some sort of installer tool, rather than tapping them on with a drift. This ensures the seal is installed correctly and at the right depth in the seal retainer to prevent leaks.
