Have a 2007. 5 6. 7L Diesel 2500 RAM. I have 25K on the truck and I am on my 3rd "Power Steering Pump to Hydraboost hose". (Mopar 52122339AB). #@$%! Doesn't leak; just suddenly sounds like the fluid is swooshing through hose. Seems the plastic liner inside the hose breaks down somehow. Dealer says they don't know the root cause. Anyone else have this problem or know the cause?
