I followed this to the "t" in order to put my Sylvania Silverstar Ultras in my 2011 Ram. I didn't remove the grill, but I did undo the top screws and pop the bottom brackets off slightly. There are a few tabs on the insides of the headlamp assembly that need some extra clearance when removing. I put 4 new bulbs in for the highs and lows, and Sylvania Silverstars in for the fog lights. They aren't making a 9145SU anytime in the near future, so I had to compromise. I'll keep everyone posted on the 'perceived' improvement. Just waiting for it to get dark.
