Weight Distributing Hitch for 2010 Ford Expedition EL

I just went from a Reese HP wdh with no sway control to an Equalizer 4 Pt 10k hitch. Works great! For noise, keep the sockets lubed as per Equalizer's instructions. I use marine grease. I went against heaven above and put some grease on the spring bars and L brackets, then wiped off with a rag. Nice and quiet while still offering good sway control "in my humble opinion". We didn't have a sway problem before but it still prevents waggle from passing trucks.
