Tie Rod End Removal and Installation For complete tie rod service information, refer to Maintenance Manual 2, Front Non-Drive Steer Axles. 1. Wear safe eye protection. Park the vehicle on a level surface. Block the wheels to prevent the vehicle from moving. 2. Use a jack to raise the front of the vehicle so the wheels are off the ground. Support the vehicle with safety stands. WARNING Support the tie rod assembly during maintenance and service to prevent serious personal injury and damage to components. 3. Use a paint pen to mark the position of both tie rod ends as shown. Be sure to mark it well so the tie rod end can be screwed back into the exact same position on the threads. Also count the amount of visible threads to confirm proper depth upon re-installation. Figure 1. CROSS TUBE 1000027c TIE ROD END TUBE MARKS SLOT BOTTOM VIEW Figure 1 NOTE: Perform the clamp retrofit procedure one side at a time. 4. Remove the cotter pin and nut that fastens the tie rod end to the tie rod arm. Figure 2. 4005184c TIE ROD ARM TIE ROD CROSS TUBE END NUT COTTER PIN Figure 2 WARNING Use a brass or synthetic mallet for assembly and disassembly procedures. NEVER hit steel parts with a steel hammer. Pieces of a part can break off. Serious personal injury and damage to components can result. CAUTION Do not heat the tie rod arm to remove the cross tube assembly. Heating the tie rod arm may soften parts. Damage to components will result. 5. Disconnect the cross tube assembly from the tie rod arm. If available, use a tie rod end puller to separate the tie rod end from the tie rod arm. Figure 2. If necessary, use a leather or plastic mallet to tap on the end of the tie rod arm. 6. Remove the tie rod end clamp bolt. 7. Remove the tie rod end out of the cross tube. Rotate counterclockwise to remove passenger side tie rod end; rotate clockwise to remove driver side tie rod end. 8. Remove the old tie rod end clamp and discard. 9. Slide the new tie rod end clamp into position. Loosely install the nuts and the bolts into the clamps. 10. Thread the tie rod end back into the same position utilizing the paint pen marking. Exposed threads should match the value noted in Step 3. 11. Be sure that the clamp tab is firmly seated against the end of the cross tube. Align the clamp opening with the cross tube slot as shown in Figure 1. Tighten the clamp bolt nut to 150-175 lb-ft (203-237 Nm). 12. Re-install the tie rod into the tie rod arm. Thread the old nut on and tighten to 160-320 lb-ft (216-434 Nm). 13. Install a new cotter pin. If necessary, tighten the nut until the holes are aligned. Do not loosen the nut to install the cotter pin. 14. Repeat for the opposite tie rod end. 15. Use touch-up spray paint to match the original color. 16. Return the vehicle to service.

October 31, 2022 IMPORTANT SAFETY RECALL: 22V-788 Meritor Tie Rod Clamp This notice applies to your vehicle VIN: X UNIT: 1xxxxx This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. E-ONE has decided that a defect which relates to motor vehicle safety exists in certain models of the following emergency vehicles manufactured April 27, 2022 to October 5, 2022, equipped with Meritor Tie Rod Clamp: E-ONE – Cyclone 2, Cyclone N, Typhoon N WHY IS A RECALL BEING CONDUCTED? Based upon information provided by Meritor’s supplier, due to a heat treat issue, Meritor has determined that a population of tie rod clamps used in the manufacture of the subject axle population may be susceptible to cracking. Over time, a crack may lead to a complete fracture of the clamp, thereby reducing clamp load to the tie rod end. If both clamps on the tie rod were to fail, the cross tube could start to unscrew, vehicle alignment issues would evolve, and there is a potential for the tie rod end to separate from the cross tube. Separation is more likely to occur when tie rod loads are highest, which is at slow vehicle speeds over rough terrain or turning maneuvers. This defect could result in separation of the tie rod end from the cross tube could result in partial loss of vehicle steering capability, increasing the risk of a crash. The initial effect would be a vehicle out of alignment. If both clamps on the tie rod cracked, the tube could rotate and result in a partial loss of steering capability. Excessive carbon caused by a damaged control board on one of four furnaces at the supplier. The affected item is the Meritor Tie Rod Clamp. WHAT ARE WE DOING ABOUT THE PROBLEM? Meritor will work with affected vehicle manufacturers to replace suspect tie rod clamps on the subject axles. The affected emergency response cab chassis is still within their warranty period and would not be subject to reimbursement. The repair will take approximately 2 hours to complete. Vehicles subject to this recall are to be inspected and repaired by an E-ONE certified dealer or technician or authorized Meritor Service Center. E-ONE will compensate the dealer or owner for installing new Tie Rod Clamps, provided free of charge, if it has not already been replaced during normal maintenance.
