In this video I am going to share with you a willys Jeep steering knuckle upgrade that I have been doing for many years with zero problems. I first did this back in 1988 when I was working on a CJ2A. The customer was installing larger tires and was doing some off roading. After a while each of his wheeling buddies came to me wanting the same thing done so they wouldn't have to be towed off the trail again. Plain and simple, this is an easy upgrade and your knuckle/spindle joint will never come apart again. This will work on CJ's, wagons, trucks, early wagoneers, etc...... vehicle with a closed knuckle can benefit from this upgrade.
