What's the recommended lube for the differential on a Gillig chassis? Not interested in going the synthetic route.
Capacity?

I am not exactly sure but from information here on Barthmobile the Gillig used Dana 90. I have refilled my rear differential with about four gallons of synthetic 70 w 90 gear oil. about the synthetic, but I use synthetic oils whenever possible.

Call Gillig.

Thanks for the informative reply Kevin.
