Revamping some cars for my sons to play with outside.
running 17.5t on a 88/53.
i have 2 sealed diffs with metal gears & 2 normal plastic ones.
wondering what I should do for diff locations & thicknesses of oil/grease.
should I run the sealed units in the front with thick oil or run them in the rear with a 5k oil & thick grease in the plastic diff in the front.
Just fooling around outside .
