I just got done rebuilding my '93 Dodge Dakota rear diff.
8 1/4" diff.
Seems that IF you tow or haul heavy with them the rear pinion bearing fries!
(I bought my truck cuz it HAD the towing package)!!!
I had replaced the oil last spring with Mobil 1 75-90 before the 250 mile haul, on the way home I started to hear the "growl" thought it was tires.
A few weeks ago it got too loud.
Had to do a total rear axle rebuild.
This time I switched to Amsoil 90-140 heavy duty oil.
Keep and eye on those rear diff. temps, swap your oil as oil break down may have been the cause of mine, (although the web is full of horror stories about Mopar pinion problems.
Would I buy another Mopar truck-in a heart beat!
