I found out by the dealer that there is a change in the amount to add to the
rear axle if you change the gear oil. If your truck has the Trac lock,or
limited slip,,, originally the amount of Posi additive was one bottle (4 0z)
Now the requirement is (Two) 4 0z bottles of Posi additive, this is to
keep the gears from wearing out along with the Posi unit. Maybe this is why
in the past some have complained about the 3;55 gears wearing out????
