  Q: How to Overhaul the Rack and Pinion in Power Steering Systems on Scion xA?

  A: The first step to overhaul the POWER STEERING LINK ASSY involves using power steering fluid or molybdenum disulfide lithium base grease on specified areas. The service sequence begins with removing the FR WIPER ARM RH and LH, HOOD TO COWL TOP SEAL, COWL TOP VENTILATOR LOUVER RH and LH, WINDSHIELD WIPER MOTOR & LINK ASSY, and COWL PANEL SUB-ASSY. The COMBINED FRONT WHEEL area requires inspection before removing the STEERING COLUMN HOLE COVER PLATE. The steering wheel should stay fixed by seat belts to maintain stability during the separation process before placing matchmarks on both the sliding yoke sub-assy and intermediate shaft and loosening their bolt connection. Propagate clip A to detach the STEERING COLUMN HOLE COVER SUB-ASSY NO.1 without damaging clip B. Remove the HOOD SUB-ASSY and power steering fluid then remove FRONT WHEELS. Using Special Service Tools 09620-62011 and 09628-62011, remove the TIE ROD END SUB-ASSY LH and RH and then detach the ENGINE UNDER COVER LH and RH. Disconnection of the PRESSURE FEED TUBE ASSY requires removal of its clip while using Special Service Tool: 09023-12700. Use Special Service Tool 09628-00011 to separate the FRONT SUSPENSION ARM SUB-ASSY LOWER NO.1 on both the left-hand and right-hand sides. Two No.1 engine hangers (Parts No.: 12281-21010, 91642-81025) will be used for suspending the ENGINE ASSEMBLY. The workshop uses two No.1 engine hangers (part number 12281-21010 and bolt 91642-81025 fixed at 40 Nm) to suspend the engine assembly during FRONT SUSPENSION CROSSMEMBER SUB-ASSY removal. Move the POWER STEERING RACK HOUSING HEAT INSULATOR and STEERING COLUMN HOLE COVER SUB-ASSY NO.1 together with STEERING INTERMEDIATE SHAFT while noting original positions before disassembly. Remove the POWER STEERING RACK AND PINION following a marking procedure and removing its bolts, nuts, bracket No.2, grommet No.2, along with the assembly while torquing the bolt once nut is fixed. Use Service Tool 09023-38200 to remove the STEERING RIGHT TURN PRESSURE TUBE with its O-rings similar procedure occurs for the STEERING LEFT TURN PRESSURE TUBE. Set up Special Service Tool: 09612-00012 to fix and uninstall the POWER STEERING RACK AND PINION and thereafter loosen the TIE ROD END SUB-ASSY LH and RH lock nuts while retaining their positions. Cautiously detach the STEERING RACK BOOT CLIPS and clamps before taking off the STEERING RACK BOOT NO.2 and NO.1. Use Special Service Tool: 09922-10010 to remove the STEERING RACK END SUB-ASSY and proceed to remove the RACK GUIDE along with the POWER STEERING CONTROL VALVE by marking components positions then removing bolts. To proceed with the removal operation use Special Service Tool: 09950-70010 (09951-07200) and a press so you can eliminate the CYLINDER END STOPPER and POWER STEERING RACK followed by removing the POWER STEERING RACK BUSH and its oil seal. Take the RACK STEERING PISTON RING out carefully then measure POWER STEERING RACK behavior using a dial gauge to check both wear and runout. Check turning torque values of TIE ROD END SUB-ASSY LH and RH while placing them in a vise. Reinstall the POWER STEERING RACK HOUSING OIL SEAL yet use power steering fluid as a coating before adding the RACK STEERING PISTON RING in its correct position and with proper fluid application.

  Q: How to overhaul the alternator assembly on Scion xA?

  A: The generator assembly overhauling process begins with pulley removal by utilizing Special Service Tool 09820-63010 (09820-06010, 09820-06020) to connect the tool to the rotor shaft and applying a torque of 39 Nm (400 kgf.cm, 29 ft.lbf) to the socket while turning it clockwise. Tighten the pulley nut counterclockwise until it reaches a half turn then you can detach the generator from its adapter while also taking out the pulley nut and pulley. You can start by disconnecting the rear end cover where you first remove the nut followed by the terminal insulator and bolt and three nuts and plate terminal. Separate the generator brush holder from the generator regulator by removing the brush holding cover and unscrewing screws and proceeding to remove all three screws from the regulator. Use Special Service Tool 09286-46011 to detach the generator holder with rectifier through four screw removal then extract the generator rectifier end frame by discarding four rubber insulators and the seal plate with four nuts alongside the clip code. You should start rotor assembly removal by taking away both the generator washer and then gently pull out the rotor from the drive end frame. The generator regulator assembly should be checked for proper functioning while testing the continuity between F to B and F to E terminals. The generator rotor assembly between slip rings should have 2.1 to 2.5 Ohm resistance at 20 degrees Celsius (68 degrees Fahrenheit) and must have proper ground continuity. The diameter of the slip ring must be measured with vernier calipers to check it stays within the accepted range of 14.2 to 14.4 mm (0.559 to 0.567 in.) and exceeds 12.8 mm (0.504 in.). Check the bearing wear and perform a replacement when needed on the generator rotor system. An ohmmeter assessment should be performed on both positive and negative rectifiers of the generator holder with rectifier to check for proper functionality. The stator coil requires testing for open circuits while checking for ground continuity before replacing the generator assembly. Check the brush length exposure measuring 9.5 to 11.5 mm (0.374 to 0.453 in.) while being at least 4.5 mm (0.177 in.) since this determines brush holder assembly replacement eligibility. The installation process of the generator rotor assembly requires you to return the rotor along with the washer into its proper position. The generator rectifier end frame installation requires a 19 mm socket wrench for pressing in while securing it with four nuts and clip code at torque specifications. Apply the seal plate and rubber insulators while installing them according to their designated orientation. Reattach the generator holder with rectifier through four screws while keeping to specified torque values then connect the generator regulator assembly through three screws followed by two screws for the generator brush holder assembly with correct installation direction. Connect the rear end cover and terminal insulator where specified torques apply followed by generator pulley installation through hand-tightening the pulley nut before achieving final torque of 111 Nm (1,125 kgf.cm, 81 ft.lbf) using the holding tool to check smooth wheel movement.

  Q: How to service and repair the Control Arm for the Automatic Transaxle on Scion xA?

  A: Service engineers should start FRONT SUSPENSION NO. 1 LOWER ARM repair by removing both front wheels and hood sub-assemblies to suspend the engine assembly. You can disconnect the FRONT SUSPENSION NO. 1 LOWER ARM SUB-ASSEMBLY LH by removing the clip along with the nut while using Special Service Tool: 09628-00011 to separate the lower arm from the steering knuckle. Perform the same steps to disconnect the FRONT SUSPENSION NO. 1 LOWER ARM SUB-ASSEMBLY RH. To disconnect the FRONT STABILIZER BAR begin by securing the stabilizer bolt with a wrench to remove the nut followed by taking off the 2 retainers and the cushion then the stabilizer bolt while repeating on the opposite side. First disconnect the POWER STEERING LINK ASSEMBLY by taking out the 4 bolts and nuts and suspending the steering link while doing so before disconnecting the PRESSURE FEED TUBE ASSEMBLY through bolt removal. Remove the FRONT SUSPENSION MEMBER REINFORCEMENT LH and RH by extracting both their 2 bolts. Start by detaching the FRONT SUSPENSION CROSSMEMBER SUB-ASSEMBLY after removing its bolt and 2 nuts then set the crossmember on a jack after which remove the remaining 4 bolts. Mucho Workshop will disconnect the FRONT SUSPENSION NO. 1 LOWER ARM SUB-ASSEMBLY LH by extracting all its 2 bolts, the nut, and the lower arm without spinning the nut. Before attaching the nut to the FRONT SUSPENSION NO. 1 LOWER ARM SUB-ASSEMBLY LH you must pivot the ball joint stud 5 times in each direction. You should then use a torque wrench to turn the nut steadily at a pace of 2 to 4 seconds per turn and read the torque on the fifth rotation. The FRONT SUSPENSION NO. 1 LOWER ARM SUB-ASSEMBLY LH must be preliminarily installed with 2 nuts and 1 bolt before connecting the FRONT SUSPENSION CROSSMEMBER SUB-ASSEMBLY through alignment using Special Service Tool: 09670-00010 followed by bolt A installation at 70 Nm then bolt B installation at 116 Nm and completing the installation with a bolt and 2 nuts torqued to 80 Nm. Secure the FRONT SUSPENSION MEMBER REINFORCEMENT LH and RH with two bolts that reach 47 Nm torque. First bolt together the PRESSURE FEED TUBE ASSEMBLY with the bolt requiring 7.8 Nm torque strength and then attach the POWER STEERING LINK ASSEMBLY using four nuts along with four bolts at a torque strength of 74 Nm. Install the 2 retainers along with cushion before applying a wrench to the stabilizer bolt to secure its nut (Torque: 18 Nm). The FRONT SUSPENSION NO. 1 LOWER ARM SUB-ASSEMBLY LH must connect to the steering knuckle with a nut that reaches 98 Nm torque value while a new clip needs installation before increasing the nut torque an additional 60 degrees when the clip holes are misaligned. Install the front wheel on both sides by following the specified torque of 103 Nm. Fasten both bolts on the FRONT SUSPENSION NO. 1 LOWER ARM SUB-ASSEMBLY LH with a torque of 88 Nm for bolt A and 132 Nm for bolt B and avoid rotating the nut during installation. Check and modify both the hood sub-assembly and front wheel alignment before concluding.

  Q: What are the essential steps to perform a diagnostic system check on the seat belt and Air Bag components after a collision on Scion xA?

  A: Checking the seat belts together with Air Bags must become necessary after each crash event. A visual examination of the horn button assembly is required on vehicles that have not experienced a collision to check for breaks or alteration of color or cracks in the assembly structure. After a collision with undeployed Air Bags inspect the horn button assembly for identical damage through removal so you can also examine steering wheel assembly and horn button contact plate for deformation. Recover the entire horn button assembly when facing deformed condition on the horn button contact plate. Implementation of the horn button assembly should maintain proper spacing from the steering wheel assembly. An evaluation of the instrument panel passenger Air Bag assembly requires diagnostic testing alongside visual inspection of possible damage present before and after vehicle disassembly. The assembly must receive new components if any show deformation or cracks. The inspection protocols are identical for the curtain shield Air Bag assembly along with the front seat Air Bag assembly and SRS wire harness and connectors where inspectors verify both the existence and conditions of cuts and cracks and material damage. The replacement process includes the Air Bag sensor assembly center and front sensor and rear sensor and side Air Bag sensor assembly depending on Air Bag deployment status. Check that the seat position Air Bag sensor and front seat inner belt assemblies operate correctly while performing resistance tests on all components which do not comply with specifications.
