Hello all,
Im looking at changing my front diff fluid while I have it apart for new seals. My owner's manual says 75w90 for front and 75w140 for rear. however, I thought there was a TSB out stating that the front should also receive 75w140. Can someone verify this? Also, what is the capacity of the front and rear diffs.
My truck is a 99 F250 Super Duty.
