1 52113926AF Power Steering Hose - Pump to Hydraulic Booster .
I had this on my new '03 Dodge/Cummins. Really bad vibration in the steering wheel and the go pedal.
The fix was a new hyd hose with about 2 lbs of weight crimped to the hose to dampen very severe hyd vibrations. I thought the '04 had this fixed on assy line but won't hurt to check.
