It provides the means for the drag link, in connection withthe steering arm, to change the lateral movement into turning and Benefits:Since the king pin is the very heart of the axleassembly, it is mandatory for a replacement part of this nature to be of thehighest quality. All Dayton Parts pins utilize high quality steel and are heattreated for superior strength and long service life.

6 A satin smooth micro-finishinsures minimum steering effort yet retains the ability to hold grease for Types:Dayton Parts offers the installer three distinct types ofbushing materials. Each has its own unique (Delrin) bushingsprovide reduced steering effort and are fast toinstall since they do not have to be fitted. They are generally onlyrecommended for vehicles which spend most of their time on-highway. Theytend to wear out faster than bronze bushings in severe service backed bronze (bimetal)has traditionally been the bushing materialof choice of many mechanics. Very close bushing to pin clearance can beobtained either by honing or reaming. They are more tolerant of contaminantsthan nylon and provide considerably longer milage in severe serviceapplications such as refuse and dump vehicles, bushingsare now being utilized in new axle production by mostNorth American axle manufacturers.

7 These incorporate a steel backing as withthe bronze bushings. However, the inside diameter features a low friction acetylresin polymer surface which is dimpled and grease grooved for better greasedistribution than the older nylon designs. The bushing is usually shorter than itsbronze counterpart. They may or may not require fitting depending on the axlemanufacturer s design. However, only reamers can be used if required. Ingeneral, more care must be taken when installing to prevent damage to Procedures - King Pin PlayRoutine:Install a dial indicator so that the base is on the I-beam and the tip isagainst the side of the top of the knuckle. Set the dial indicator to zero andmove the top of the tire side-to-side after raising vehicle and installing jackstand.

8 Repeat for lower bushing. If dial indicator moves a total of foreither, replace with a new king pin Inspection:Apply service brake to eliminate wheel bearingmovement. With front end lifted and jacks installed, grasp tire at top andbottom and attempt to move in and out. Reject the vehicle if measurements atthe top or bottom of the tire at the outer circumference is greater than :Inspection methods listed here are highly abbreviated. Always refer to vehicle oraxle manufacturer s service manual for correct step-by-step or less17 to 18 over 18 1/4 3/8 1/2 Wheel Size:4 Tie Rod EndsCatalog 222 TieRodEndsFunction:Connects the tie rod arms of the spindles to transfer the steeringforce. Provides the ability to fine tune wheel toe-in to achieve optimum tire and Benefits:Dayton Parts tie rod ends feature a dual bearing alongwith a preloaded, self-adjusting spring that limits ball stud end movement andcontinuously compensated for ball and spherical bearing surface features add up to a ball socket that withstands the punishment of severeservice applications while providing significantly increaded service life over Designs:Dayton Parts sockets utilize the same seal design as specified bythe axle manufacturer or truck Sliding seal is the most common.

9 When rocking motion of the ball studoccurs, the seal slides over the socket body maintaining full contact. The Sliding seal allows for the purging of contaminated grease during Boot seal is always used in permanently lubricated sockets or may bespecified in severe service environments with relube designs. A metal reinforcingring molded into the seal aperture snaps over the socket body, holding it inposition as the stud oscillates. The rocking motion of the ball stud isaccommodated by flexing of the convoluted part of the Anti-Tilt seals are useful in applications where the vehicle manufacturerwishes to restrict the ball stud movement or control a defined travel path. Therigid seal assembly pressed down over the ball stud and snaps firmly over thesocket body shoulder.

10 All angular movement of the ball stud is eliminated, whilestud rotation is Procedures - Wear LimitsGrab and try to move the tie rod cross tube in any direction. If movement orlooseness is felt between the tie rod ends and the tie rod arms, remove and replacethe tie rod ends. Check the seals for rips at the time of removed, use a torque wrench to measure the ball stud turning torque value. Ifit takes less than 5 inch pounds of torque to rotate the stud, replace the tie rod inspection station purposes, place the vehicle out of service if lateralmovement(using hand pressure only)exceeds 1/8". Do not use leverage as thiswill overcome the preload LinksDrag LinksCatalog 222 Drag Link &Drag Link EndsFunction:A drag link connects the pitman arm on the steering gear with thesteering arm on the spindle.
