How to Use a King Pin Reamer
- 1). Install your steering knuckle assembly in the vise with its brass jaws. You can mount the knuckle components in the vise either horizontally or vertically while performing the reaming procedure.
- 2). Insert the king pin reamer into your steering knuckle until its blades touch your king pin bushing.
- 3). Rotate the king pin reamer, applying light downward pressure in a smooth pattern. Make sure you do not apply too much pressure.
- 4). Slide your king pin reamer out of the steering knuckle assembly's bottom part. Rotate your reamer opposite its cutting rotation direction if you need to remove it from the top.
- 5). Clean and remove your king pin bushing material from your steering knuckle assembly, while making sure to remove the material from the assembly's grease channels and dimples.
- 6). Use a wire wheel to clean the 5/8-inch bolts of the brake backing plate, and run a tap right through the lower steering knuckle assembly threads. Flush it out with your brake cleaner, and dry it with compressed air.
