Clearance between Knuckle Shaft (Kingpin) and Bushing
1. Measure the shaft O.D. at several points where it contacts with
the bushings.
2. Measure the bushing I.D. in the same method, and calculate the
clearance.
3. If the clearance exceeds the allowable limit, replace the
bushing.
(When reassembling)
• Remove the bushing with a bushing puller.

Steering Cylinder I.D.
1. Measure the steering cylinder I.D. with a cylinder gauge.
2. If the cylinder I.D. exceed the allowable limit, replace the
cylinder tube.

Clearance between Rod and Bushing
1. Measure the bushing I.D. with a cylinder gauge.
2. Measure the rod O.D. with a outside micrometer, and calculate
the clearance.
3. If the clearance exceeds the allowable limit, replace as a unit.
