Re: capacity of front, rear diffs and t case?
Unless you commute to work up streams, like lal357(lots of changes due to water contamination), go to fully synthetic 75W90 gear lube and fully synthetic Castrol mercon tranny fluid. I get my gear lube at any Dodge dealer, it's still about $9.00/quart Canadian (American pocket change) and it's clean as a whistle when I dump it/vacuum it (front axle) every year or two.
WD-40 is spot on the numbers I use for buying amounts.
