King Pin Lube September 02, 2022, 04:43:08 pm Some helpful soul posted awhile back about installing zerks for the king pins (sorry, can't find the post so no attribution). Anyhow, In addition to the four grease points up front I've added four more. Here's a couple of photos. I installed a straight zerk in the bottom pin and an angled one for the easy access to the top pin. (the factory plugs came out easily) I got three pulls on a hand grease gun into each. Good to go.jor 1 Likes
