From here it's installation of all the parts. You'll know what I mean from the instructions and the parts in front of you.Īfter installation the knuckles should move freely with very very little resistance. You want to be able to tap in the bearings with some resistance. Don't forget to shim everything fairly tight. It can also be tricky putting in the spiral bushings, but once you get the hang of it you'll be fine. You also have to load up the bearing with grease. The Kaiser kingpin set comes with good instructions. Clean everything up real nice, including the axle eye. This can take a lot of work.Īfter the knuckle is removed you take the seals and the bushings out (with previously mentioned bushing driver).

After the caps are removed you remove the draw keys and should be able to pound the kingpins out. Eventually the nut broke and my dad welded a rod to the kingpin cap. I had screw in ones and had to put 800 + ft lbs on a very shallow nut. Depending on style they can be a real bitch. To remove the steering knuckle you need to remove the upper and lower kingpin caps. Also check your wheel bearings/races and replace if necessary. Brake chambers to make it easier to take the knuckles off, but not necessaryĪt this point I would recommend a new drag link, new tie rod ends, Check your s-cams and bushings/ replace if necessary.

If I embark on this adventure, how much time should I plan on it taking? Any suggestions on where I might get more reasonably prices parts than what Peterbilt will offer? Any non-standard tools I might need? Any tips, tricks or suggestions anybody can offer would be greatly appreciated. Given that I have my own shop and, while I’m no mechanic I am a pretty accomplished parts-swapper, should this job be easily within the scope of my abilities, or should I go down to my local Cummins dealer and let them rape me like they usually do? My problem is that I’ve never done this before and don’t want to turn a minor problem into something major and very expensive. My tractor (2006 Pete 387) is no spring chicken (858k miles), and as I’ve been experiencing some unusual steer tire wear (yes, it is properly aligned and I have Road King shocks and Centramtics and Tru-Balance wheel centering sleeves), thought I might try replacing the king pins. I know I’ve seen a post on here on the same topic, but I couldn’t find it, so here goes…
