said 75-140 on tag,
thanks for help,

whats downside when i have wrong oil there ?`

then what brand is good, can i use what i want here ??

[ryandamo]

i had 75w 90 in my rear for a few months by accident, its fine, but if you do alot of long distance high way driving or tow with it, you should change to 75w140 because it handles the heat better. have to keep in mind that with the rear axle, the differential fluid also lubricates your wheel bearings unlike the front axle.

Use only AMSOIL!

You asked. Rumors have it FORD may start using AMSOIL from the factory. Would be a complete departure from what AMSOIL has always supported - small business.

[MountainMan]

Last week I changed both front and rear differentials with Schaeffer's 75W-140.

[Nyberg]

how about castrol oils, its easy for me to get,
amsoil they dont have here.
