Hi all,

I am getting ready to do a change of fluid on the the differentials and the transfer case. Which is the best weight to use in the rear diff?

Thanks,

Scott

I used Mobil One 75w90 full synthetic in front diff, rear diff, and transfer case a few months ago. Seems like most guys on here run that viscosity.
