Description:
The kingpin D60 (common to all GM axles and early Ford and Dodge axles) uses a tapered plastic bushing and preload spring to locate the top of the steering knuckle. As everything wears and we put big tires with lousy balance on the truck, it's common to develop what's known as "death wobble". You typically know it if you have it, at roughly 25 mph the front tires will start a violent oscillation that typically requires you to come to a complete stop before it will go away.
One of the contributing factors in death wobble is wear on the tapered kingpin bushing and fatigue on the preload spring. A less common problem is actual breakage of the bushing, this usually only happens with a really big hit on the front end. The broken bushing below resulted from a 5500# truck coming down on the left front tire from a considerable height. The wheel also bit the bullet on this one.
So, whether your damage is due to use (abuse) or simply long term wear, ORD have the spring and bushing kit to get the proper alignment on the upper kingpin.
Kit Includes:
- 2 springs
- 2 bushings
- 2 new spring cups
