'12 Ram 2500 rear dif leak ( fleet trucks) gas & diesel
 

Need to find out if anyone is having the same rear dif. leaks my fleet is experiencing. I have over 250 light duty trucks and around 40 (growing number monthly) 2012 Ram 2500's gas and diesel's i have had to send almost 1/3rd of them to dealer for warranty work because of pinion seals, and pass rear axle seals blowing. The trucks have squeeky brakes from as low as 3k miles and dif leaks from 30-60k miles yes they put that many on these trucks in a year. Most of the Foremen dont tow but haul gang boxes with them, all vent tubes have been clear and I service the Dif @32k on all the trucks. ANY ideas or anyone else experiencing this, i cant afford to have the trucks down for 2 days and Foremen sitting on their A$$es the local dealership has almost reserved a lift and parking spots for my trucks!!!! Im a Master tech so ur not dealing with a dee dee dee.
