On 06/16/2020 I went to dodge dealership to have egr valve replace. While there,service member recommended I should have my front differential service due to the mileage on truck, I agreed. I never had any problems with my front differential. No leaks e.t.c. I had my front differential service here on 06/16/2020. On 06/17/2020 ,coming from New Jersey, I notice front differential leaking badly. Took truck back to dealership to diagnose problem. Service member stated technician didn’t fully seal drain plug and fluid leaked out. Truck was serviced (new fluid and plug tighten properly)and return to me on 06/18/2020. No apology given , discount or coupons , nothing. On 06/26/20 I notice fluid leaking from front differential again, so truck was returned to dealership on 06/26/20. Technician diagnosed a rear pinion seal leaking and dripping down onto the front differential which is connected directly to front differential. Technician repaired rear pinion seal for $380. I ask “shouldn’t it be free because it’s part of the front differential”. Service member Stated rear pinion seal didn’t have anything to do with front differential. Today 07/18/2020 I notice front Differential leaking slowly and a grinding sound coming from front differential when driving and accelerating. Drop truck off at dealership on 07/18/2020. What should I do?
