2001 F250 V10 knocking problem
 

I have an f250 V10 and it seems to be knocking on the passenger side mostly when I accelerate I've replaced spark plugs, fuel pump, and fuel filter knock sensor, map sensor, changed the oil I put good gas in truck it has over 300,000 miles never runs hot and doesn't knock all the time. Was seeing what else I could look for or what I've missed. Any help would be appreciated.
