I upgraded my gearing to 5.13:1
Two weeks later, my Dana 44 rear blew apart! Destroyed the bearings and my new ring and pinion.... was determined it cooked! Generating way too much heat!
Since then, I learned a shit ton about diffs, and that there is a very specific break in procedure for new gears, WHICH no one explained to me.... therefore I've taken responsibility as it was my fault since I use the freeway for work, and may have put way to much strain on my new gears too early....
That leads me to now.... I've been anal about following this new gear break in to the T. And due to rapidly grown paranoia, I drained the fluid to service it at 164 miles on the new gears... burnt and black.
Then when I was filling it, after cleaning it... I noticed a difference and now I'm confused again!
Pictured is my rear diff with Rancho rock gear diff covers.... the fill hole for these covers is much higher then the factory placement for my Dana 44. And according to the information I have in ALLDATA, Chrysler lists a capacity spec of 2.25 quarts of Synthetic 75W140 gear oil with a LSD additive. And maybe I'm thinking old school here, but when I filled it up, it tool almost 4 full quarts to get to the fill hole!
So, how much fluid goes in here???
Can too much fluid also cause the rear to "cook"?
I hope I'm not the only one who has experienced this. :-(
So, had rear rebuilt.... again.
