2012 Dodge Ram with 4.7 litre engine. Noticed a ground out vibration type noise at low speeds and at idle in gear at stop light there was a really noticeable vibration in steering wheel. Found power steering pump to be loose and under further investigation found that there were no threads in mounting bolt hole at the 9:00 position and the lower bolt at the 6:00 position in the end of the cylinder head. Therefore there was only one bolt holding on the power steering pump and it had loosened up and now the pump and line were vibrating. Vehicle is being repaired at dealership by replacing the cylinder head. This vehicle should have never left the plant in this condition and definitely should not of left the dealership. This shows very poor quality control at both the plant and dealership new vehicle prep department. I do not believe this could be an isolated incident and further investigation of vehicles with this engine built at this time should be investigated. This truck was delivered to the dealership in mid November not sure of exact build date due to truck not being in my possession right now it is at the dealer for repair.
