My 2005 RAM 1500 Quad 4x4 at 46K miles has developed a knock/rub in what feels like the right front. I feel it thru the floorboard and gas peddle mostly between 15 and 20 miles an hour. I thought it was possibly a warped rotor but not. Original pads replaced and rotors turned with no change. Any thoughs as to where to look next?

 

stearing linkage upper and lower. if you feel it threw the gas pedal and stearing wheel thats the ticket.
if not you may have some slack in the lincage from the toe rods ect.
