I have a 2002 F150 FX4, The tag from the rear end reads top line 3 V919A, next line reads 3L55 9751K02 From what I'm reading 355 limited slip with 9.75 ring gear, but in reading other notes the 919A is not limited slip, it would have to have a B to be limited slip, I know that the 9.75 ring will make a difference in the axle bearing used. Am I correct on the above?
