Thanks Roninofako! Yes, I found a field service manual on line (actually several), but all of the other info I quoted from my Owner's Manual. I wasn't sure what to put in the rear axle, but I think I will go with the 75W-140. Which, BTW, I saw in another service manual (93) that for the Chrysler rear end, it is not called Trac-Lok, but is referred to as 'Sure-Grip limited differential. And according to Schaeffer Oil, theer oil already has the LSD additive.

 

I always fill every axle and transfer case I service, to the fill hole, it's never caused an issue.

 

Same.
