Applying brakes will help lock wheel assembly. Note: Locate indicator on a smooth, flat surface for best reading. 8 Make sure the boot completely covers the ball joint of the tie rod end with no cracks or tears. If there is damage to the boot, the entire tie rod end must be replaced. The threaded portion of each tie rod end must be inserted completely in the cross tube split. This is essential for adequate clamping. Replace components if this fit cannot be obtained. CORRECT The threaded portions of both tie rod ends must be completely inserted in cross tube split Equal threads exposed on left and right tie rod ends - Cracked or torn boot requires entire tie rod end replacement INCORRECT Threaded end is not completely inserted in cross tube split. Make sure the tie rod nut is torqued to the proper specifications and the cotter pin is correctly installed in the nut. If the cotter pin is missing, the tie rod nut could become loose and steering will be affected. - Steering knuckle - Missing cotter pin 4. Where zerk fittings are necessary, make sure they are installed correctly. (Non-greaseable tie rod ends do not require zerk fittings.) 5. To protect the cross tube, use only your hands or a pipe wrench with jaw protectors to rotate the cross tube. Make sure the cross tube will turn toward the front and the back of the vehicle. Replace both of the tie rod ends if they will not turn in both directions. 6. If the cross tubes or clamps are bent, cracked or damaged, replacement is necessary. Do not attempt to repair a cross tube as this could result in damage to the axle. 7.https://www.formuladesign.com/images/canoscan-8000f-manual-pdf.pdf Proper positioning of clamp relative to beam and correct orientation of nut and bolt are required to ensure clearance at high wheel cuts. Boot does not have purging capibilities. All grease purging takes place through pureable grease fitting. Inspection Purgeable grease fitting Note: Tie rods end inspections should always be performed prior to lubrication. If the inspection is performed after lubrication, there may be a false indication that the tie rod end is fully operative. 9 There are two separate methods that can be used to check the degree of movement in the tie rod end: a. To check axial (up and down) movement, set the dial indicator so the base of the indicator is on the tie rod arm. Then, place the tip of the indicator on the bottom of the tie rod end at the area that is most flat. If movement or looseness is detected, set up a dial indicator as shown below. b. To check radial (back and forth) movement, set the dial indicator so that the base of the indicator is on the tie rod arm. Then, place the tip of the indicator on the socket of the tie rod end. Be sure to position the dial indicator so that it is in line with the direction of movement. Set the dial indicator to zero. 4. Again, move the cross tube assembly up and down or back and forth, depending on which direction you are checking for looseness. CAUTION CAUTION Do not use a pry bar or other mechanical method on the steering linkage. Do not remove the tie rod end from the tie rod arm to check for ball stud rotating torque. This may damage the seal if a removal tool is used. Additionally, the tie rod end seal can cause false indications of internal torque. 5. Repeat Steps 0 through 4 for the other tie rod ends. Note: When one tie rod end requires replacement, it is recommended to replace both to allow for even wear on both sides of the vehicle. 0 Disconnect the tie rod end. If the cross tube is being replaced, count the number of exposed threads on the tie rod end. Loosen the clamp nut and unscrew the tie rod end. 4. Install new tie rod ends or new cross tube. Note: Cross tube has right-hand and left-hand threads for corresponding sides of the vehicle. 5. Thread tie rod end into cross tube past the tube split. The number of threads exposed from the tube should be equal on both left and right tie rod ends. Secure with slotted nut and tighten to 0-60 ft. lbs. (6-7 N m). 9. Install the cotter pin in the slotted nut and bend the ends to secure. If necessary, tighten the nut until the holes align. 6. For E and I straight socket tie rod ends, tighten the clamp nut to ft. lbs. (6-8N m). Make sure the tab on the clamp holds the end of the cross tube. Note: On tie rods with rotating clamp, position clamp with fastener away from beam. Use vehicle manufacturer s instructions to inspect wheel alignment. Negative camber is an inward tilt of the wheel at the top. Note: Total vehicle alignment is recommended when aligning the steer axle. Camber Camber is the vertical tilt of the wheel as viewed from the front of the vehicle. This is machined in at time of manufacture and is not adjustable. Positive camber is an outward tilt of the wheel at the top. - Vertical center line - Negative camber CAUTION Spicer expressly prohibits bending of axle beams (hot or cold) to change camber or for any other purpose. Positive caster is the tilt of the top of the kingpin toward the rear of the vehicle. Also Reference RP 64, Guidelines for Total Vehicle Alignment published by the Truck Maintenance Council. An angle less positive may result in vehicle wander or poor steering return to center. Caster angle is determined by the installed position of the steer axle. Caster is adjusted by adding or removing taper wedges between the springs and axle beam mounting pad. The caster angle is generally more positive with power steering, since the power-assist overcomes excessive steering effort. Note: Adjust caster to vehicle manufacturer specifications. CAUTION Spicer expressly prohibits twisting of axle beam for caster adjustment or any straightening purposes. Note: Changing the torquing sequence on U-bolts may result in slight changes in caster. 4 - Kingpin center line - Vertical center line - Front of truck 4 - Rear of truck 6. Use a work bay with a level floor. Drive the vehicle into bay slowly and straight ahead. Try to roll to a stop without the use of brakes. Position the pointer to the edge of the tape on the side that has the horizontal mark. The pointer and the mark should be at the same height. Measure the toe between the pointer and the edge of the tape on the opposite tire to get the total toe measurement. This applies to a tract or (less trailer) or straight truck with no load. If the toe measurement is incorrect, loosen the tube clamp and bolt on the end of each of the cross tubes. Turn the cross tubes until the specified distance is reached. Make sure the threaded portion of the tie ends are inserted completely and are visible in the complete cross tube slot. Tighten the bolt and nut on the ends of the cross tube to the specified torque. 4. Check the toe settings again. Also Reference RP 64, Guidelines for Total Vehicle Alignment published by the Truck Maintenance Council. Check vehicle manufacturer s manual to determine correct steering stop angle Front of vehicle - Steering knuckle - Axle beam 4 - Steering stop adjustment (both ends of axle) 5 - Degree of steering angle. Check steering angle with alignment turntable set. If adjustment is required, loosen jam nut and turn stop screw as necessary. Follow vehicle manufacture recommendations when making this adjustment. Poppet relief must be checked after adjusting stop screw setting. Note: Options for E-0I and E-46I are as follows. 8 23 Disassembly, Overhaul, and Assembly Disassembly, Overhaul, and Assembly Steering Knuckle Disassembly Preparation.

With the vehicle on a level surface, block the front and the back of at least one of the drive axle wheels to keep the vehicle from moving. Set the parking brake. Important Note: Do not raise the vehicles off the ground during greasing. If the wheels are off the ground grease will not pass through the thrust bearing properly. Keep greasing until you see clean grease being purged and the thrust bearing is full of grease. Disassembly, Overhaul, and Assembly y. Clean all grease fittings before you apply new grease. Start by greasing the top bushing grease fitting. Grease Fitting Grease Fitting Bottom Bushing Grease Fitting Top Bushing Grease Fitting Grease Until Clean Grease is Purged Important Note: Rotating the knuckle assembly during the greasing process may help to complete the purge. Do not raise the vehicle during this process. Contaminated Grease Continue Greasing Important Note: The greasing of steer axle components is not just to lubricate internal components. More importantly it is to flush contamination that may have worked its way past the seals. Greasing must continue until clean grease is purged. 9 34 Disassembly, Overhaul, and Assembly Steer Axle Grease Procedure Tie Rod End Greasing Procedure. With the vehicle on a level surface, block the front and the back of at least one of the drive axle wheels to keep the vehicle from moving. Set the parking brake. Greasing prior to taking measurements will give you a false reading. Important Note: The greasing of steer axle components is not just to lubricate internal components. More importantly it is to flush contamination that may have worked its way past the seals. Greasing must continue until clean grease is purged from the purge valve. Clean both grease fittings before you apply new grease. Grease Fitting Always measure end-play before re-greasing. Apply grease to fitting. Grease must be applied until new (clean) grease comes from the purge valve on the end of the tie rod. Under-tightening of attaching parts is just as harmful as over-tightening. Note: Exact compliance with recommended torque values will assure the best results. The same torque values apply. Check torque to make sure it does not exceed range maximum. Torque specified is for taper and threads which are clean and oil free (60-8) (6-8) (60-88) (050-65) 5- (4-4) 7-5 (-4) General Specifications Note: Torque to specifications. Tap unthreaded end of draw key sharply with a hammer, and re-torque draw key nut to specifications. Proper adjustment can also extend brake lining life by preventing lining contamination caused by seal leaks. Inspect the spindle threads and spindle nuts for corrosion and clean thoroughly or replace as required. Note: Proper assembly and adjustment is not possible if the spindle threads or adjusting nuts are corroded. Pre-lubricate all bearings. Install the inner bearing into the hub and install the wheel seal. 4. If grease lubricant is used, fill the hub cavity with the appropriate lubricant. 5. Install the hub on the spindle with care, to prevent damage or distortion to the wheel seal. Never mix grease and oil lubricants. 6. Install: The outer bearing on the spindle.
