98' F150 4WD 5.4L
Front Differential ID Tag reads;
S 976 B
355 88 7J10
Ok, I assume the gear ratio is 3.55 and th ring gear is 8.8" correct ?
What do th rest of the rest of the numbers mean ?
Does anyone know where I can purchase a good quality reman. front diff assy ?
Thanks,
JA
The S 976 B is a "stamping" number. If you need parts for the diff that's the number to give your dealer.
It's an 8.8 with 3.55s like you assumed.
The 7J10 is a build date code.
Thanks for confirming that Racreguy !
Lost the driver's side output bearing , looking for a used or rebuilt replacement.
Weird that this bearing went out - hardly ever used 4WD.
