Hey guys, what is the recommended front differential lube on the 4x4. Is it 75w-90 or 80w-90.

Use the Amsoil Series 2000 75W-90.

Greg, thanks for reply. I forgot to ask how many quarts the front end takes?

I would suggest going to synthetic if you have over 500 running (in 4x4) miles on the frount diff.
