Step 1: Determine if the Vehicle Needs King Pins

a. Attach magnetic mounted dial indicator to the top of the axle with the dial

indicator resting on the spindle eye to check horizontal movement.

b. With the wheel end and tire intact, place a pry bar under the tire and pry the tire

up and down while measuring the amount the needle swings in the dial indicator.

c. If there is 0.010” movement or more, the king pin needs to be replaced.

Step 2: Disassemble the Wheel End and King Pins

a. Remove the wheel. Remove brake assembly and backing plate.
b. Remove steering arms and cross bar.
c. Remove king pin top and bottom plates.
d. Remove lock pins. (use hardened punch – do not use heat)
e. Remove king pin. Use hydraulic press or bottle jack. (do not use heat).
f.

Keep shims for later reference.

g. Remove spindle and repeat process on the opposite side of the truck.
h. Clean up axle eyes and spindles for inspection.

Step 3: Remove King Pin Bushings and Seals

a. Using an “ST” Series STEMCO Kaiser bushing driver and a brass hammer

or dead blow hammer, pound the bushings out of the spindle eyes.

b. The bushing will push out the seal where applicable.
c. Do not use a punch or chisel, this could result in damaging the spindle eyes

beyond repair.

Step 4: Inspect the Components

a. Gauge the axle eye to determine if it is out-of-round.
b. K122E and 70.122.05 kits come with a No-Go gauge & Tech Tip #100 inside

that explains the procedure.

c. Gauge the spindle eyes to determine if they are out of round.
d. Use a micrometer & T-gauge to determine whether they meet specs

(Catalog Pg. 23).

Step 5: Hone the Axle and Spindle Eyes

a. Use a brake hone in a hand drill to lightly hone the axle eye until smooth.
b. Do not over hone, just clean up this surface.

Step 6: Install seal and Qwik Kit Bushing

Use an “ST” series STEMCO Kaiser bushing driver (Part # ST70-7 if 12k axle)
a. Install seal on end of driver with beveled edge of the seal facing out.
b. Use a brass hammer or dead blow hammer to pound seal into spindle eye until

the driver is flush with the bottom of the spindle eye. Remove driver. (For Lip
Seal Installation tips see Tech Tip # 01 577 0036)

c. Hold spiral steel bushing in hand, tilted slightly, and twist the spiral bushing into

the spindle eye turning the bushing clockwise.

d. Install it as far as you can by hand, and then use a T-handle tool (usually ST100-

1) to twist in. Tap remaining amount of the bushing into the spindle until it is flush
with a brass hammer.
