Some Dana bushings require reaming after installation. This kit contains “pre-sized” kingpin bushings
that do not require reaming. Follow the proper installation instructions provided with the parts.
Below are the installation instructions for kingpin bushing and seal replacement only. Refer back to the
proper service manual for detailed instructions on the disassembly and assembly of all other steer axle
components.
Installation Steps:
1. Remove the old grease seals from the knuckle kingpin bores with a suitable tool.
2. Drive bushings out of knuckle with the proper Removal/Installation tool. (see tool chart opposite page)
3. Remove all foreign material from kingpin areas of the steering knuckle and axle beam.
4. Wire brush machined surfaces taking care not to damage them. Clean kingpin bore.
5. When installing the bushings lightly lubricate the outside diameter to make installation easier.
6. Hand start the bushing in the beam bore.
Note: When installing kingpin bushings, position the seam in areas marked “X”. (See Figure 1)
