WARNING: Support the vehicle securely with frame on jackstands. Never work under a car supported only by a jack. Failure to provide proper support may result in serious injury or possible death.
-
Remove wheels, tires, steering arm and brake components from spindle.
-
Remove nut from kingpin lock bolt and drive out lock bolt with a brass hammer or large punch. Remove grease zerks.
-
Working from the bottom of spindle, using a hammer and suitable large punch, drive kingpin up out of spindle/axle. Remove spindle noting the location of the thrust bearing and / or any shims (if used) to ensure
proper reassembly.
NOTE: If kingpin is seized in axle and cannot be driven out, soak with penetrating oil and try again in 24 hours. If still unsuccessful, remove the axle assembly from vehicle and have kingpin pressed out. It is not recommended to use heat to free kingpin from axle boss. Excessive heat can deform or brittle the axle boss and spindle. -
Thoroughly clean and inspect spindle and axle for signs of damage, scoring, or cracks. The new kingpin should be a snug fit in the axle bore and not have any play. If it is tight, the bore can be cleaned up lightly with a brake hone. If there is excessive play the axle will have to be removed and reamed for oversized kingpin and bushings.
NOTE: Replacement of the bushings requires specialized equipment. The bushings must be reamed to final size after installation. It is recommended that the spindles be taken to a competent machinist for rework.
-
Using a suitable arbor remove old bushings and press new bushings into the spindle, aligning the grease hole of the bushing with the grease zerk hole in the spindle.
-
Align hone/ream both bushings in unison for a final clearance of .001″ to .0015″.
IMPORTANT! Incorrect installation of bushings will cause premature wear of kingpin and bushings.
-
Pack new thrust bearings with quality bearing grease. Install new grease zerk fittings.
-
Insert old kingpin up through lower arm of spindle approximately 1/2 inch. Install the thrust bearing on kingpin with metal dust shield up toward the bottom of axle boss. (Some applications may require a spacer on top of the thrust bearing.)
-
Position spindle on axle, sliding kingpin up into axle boss. Measure clearance between the top of axle boss to under side of upper arm of spindle. If gap is greater than .015″ add shim(s) as necessary to obtain proper clearance (.005-.015).
-
Install cup washer on kingpin with flat side against head of kingpin. Place felt washer on kingpin and slide up into open side of cup washer.
-
Orient notch of new kingpin toward center of axle and push kingpin down through shims and top arm of spindle, aligning the notch in the kingpin with the lock pin hole.

BRAKE INSTALLATION ALERT The selection and installation of brake components
should only be done by personnel experienced in the proper installation and
operation of braking systems. The installer must use his/her own discretion
to determine the suitability of all brake components and brake kits for every
particular application. Speedway Motors, Inc.

merchantability or fitness for a particular purpose, other than those
contained in its current catalog or website with respect to the goods

EXHAUST INSTALLATION ALERT Exhaust systems and other component surface
finishes are not permanent. Coatings, paint and other factory supplied
cosmetic treatments are only intended to protect from surface corrosion in an
unused state. No returns are allowed after the parts have been installed.
Header flanges must be clean and clear of paint and surface contaminants prior
to mating to exhaust gaskets. Exhaust fasteners must be re-torqued after the
initial heat cycle and regularly thereafter to ensure a proper gasket seal is
maintained. Should you decide to install this exhaust product at your home, be
warned that pleasure car or light duty truck/van “bumper” jacks are intended
for emergency use only. The use of frame contact jack stands in conjunction
with a floor jack as a main support is highly recommended to minimize
accidental dropping of a vehicle while the installation proceeds. We recommend
the use of a shop hoist if possible. Please use caution! Speedway Motors, Inc.
