King Pin Repair Kit: A Simple Installation How-to
Trucks and off-road vehicles may be robust, but they are not resistant to wobbling. Shaking is one of the many signs that there's something wrong with your vehicle's suspension system-and it's something that you shouldn't ignore. Linked to your vehicle's steering mechanism, king pins carry a lot of weight. They wear out overtime, so they need to be replaced in order to avoid hassles on the road. A king pin repair kit should give you all the parts you'll need for the job.
Required skill level: Intermediate
Needed tools and materials
- King pin repair kit
- Vehicle jack
- Tire iron
- Jack stands
- Torque wrench
- 3/8-inch ratchet
- Soft hammer
- Brass drift
Getting ready for the task
Use the vehicle jack to raise your automobile off the ground. Let your truck or SUV sit on the jack stands for security before removing its wheels. Use the tire iron to remove the wheels from your vehicle.
Accessing the king pin
The king pin can be found in between the steering knuckle and the I-beam. To access it, you need to remove the king pin bearing cap and bushing first. Loosen the bolts that hold the cap before you remove the spring retainer from the king pin bushing. If the cap is firmly affixed, use a screwdriver to pry it loose.
Mounting the king pin
Use the brass drift and hammer to remove the king pin from its position. Apply light pressure on the hammer until the king pin comes out. Once the old part is removed, slide in the new king pin from the king pin repair kit. Re-install all the bolts and other parts that you've taken out.
- Before you could remove the worn-out king pins, you need to disconnect the brake caliper first. You can use a line wrench to do this.
- Do not apply heat to the I-beam to expand it and to remove corrosion. Although applying heat to I-beam is a popular advice, doing so will only damage the part.
- It's best to buy king pins by the kit. A king pin repair kit contains all the things you'll need for the installation.
Kingpin Repair Kit for Trucks: How to Choose the Tools to be Used
A perfect driving maneuver starts with flawless suspension and steering systems. That is why kingpins exist ? to give you the pivot point necessary for the front axle to be turned. When your truck's kingpin is broken, replacing it immediately prevents loss-of-control accidents. Kingpin repair kits for different trucks or buses are available in the market; hence, knowing what typically comprises a repair kit is important.
Hydraulic press or pusher press
To aid in removing the kingpin bushing in trucks, a hydraulic press comes as a major component of the kingpin repair kit. When using a hydraulic press, you are given ease in taking the bushings off, removing the need for sledgehammers and torches. It is connected to the front axle and is applicable for use in both straight and tapered kingpins. The hydraulic press is sometimes called pusher press.
Soft brass drift-punch
Though most kingpin repair kits contain a hydraulic press, some unfortunately don't. In the absence of a hydraulic press, a soft brass drift-punch can be used. Aside from removing the bushings easily, a soft brass drift-punch also allows you to avoid damaging other metal parts during the repair process.
If you have a half-ton or ?-ton truck, then you wouldn't need a reamer to replace your vehicle's "floating" bushing. Reamers are used exclusively for 1 ?-ton trucks because these trucks use bushings which are press-fitted into the spindle. Since 1 ?-ton trucks require reaming, it is important to look for an adjustable straight flute reamer. This reamer avoids honing or burnishing the kingpin bushings to prevent damaging them.
Each kingpin repair kit contains its own set of kingpin removal tools. It's important, therefore, to choose the kingpin repair kit suitable for your vehicle, by identifying your truck's kingpin type. You can buy a kit which includes a reamer or a kit that has a drift-punch instead of a hydraulic press ? all depending on your vehicle's kingpin assembly.
