The instruction sheet said to use only conventional lube, not synthetic. The guy I talked to at Eaton said synthetic is "too slippery" to use in this limited-slip differential. Several YouTube vids said they are using synthetic lube with no issues. I have about 1000 miles on my Tru-Trac with synthetic lube.
Anyone here actually know the truth on the Tru-Trac??
