So the stock AAM differentials in OEM form from Chrysler aren't capable of a long life of intended service without special mail order oil and covers?
Another classic post!
Sure is weird how the OEMs are putting this bling on some of the newer hd pickups as of recent.........they must be looking to lower profit margins with the senseless add on....
So I'll take that as a yes. 75w-140 in both my '03 Cummins powered and '05 Hemi powered 2500HD's every 15k by the book. Both had carrier bearing failures in their differentials before 100k miles. Never had any trouble with the Dana axles in the 2nd gen Rams. The Sterling rear end in my F250 is still solid at 90k miles on it's original fluid.
Now you're confusing me.......I was comparing the newer trucks with OE aluminum finned covers to the aftermarket ones some are saying don't help. Insinuating that they have a real purpose if the OEs are using them in their heaviest combinations.
Not sure if you're saying your old Dodges needed these or you just don't think they had good axles?
Overall AAM axles are very stout and reliable in my experience as are Dana and frankly most every corporate pickup axle in the last uh long while. Not to say you didn't have bad ones. I had a 2nd gen went thru 3 rear diffs in the first 5k mi. But I've had a ford that scattered a trans at low miles and a Chevy that freaked out electronically and croaked.....almost brand new, just to keep it even in the brand war department, lol.
