• Q: How to service and repair the Rack And Pinion on 2006 Scion xB?

  A: The first step for power steering link maintenance involves disconnecting front wiper arms from both sides and removing the hood to cowl top seal and cowl top ventilator louvers, windshield wiper motor along with its link assembly and cowl panel sub-assembly. The center front wheel inspection leads to disconnecting the steering column hole cover plate and sliding yoke sub-assembly but only after fixing the steering wheel with a seat belt to stop rotation and marking sliding yoke and intermediate shaft positions before disconnection. The technician must detach the No. 1 steering column hole cover sub-assembly followed by hood sub-assembly removal and power steering fluid draining and finally disconnecting both front wheels. Starting with the removal of tie rod end sub-assemblies from both sides of the vehicle, the team will proceed to detach engine under covers and pressure feed tube assembly and No. 1 front suspension arm sub-assemblies. Place the engine assembly on No. 1 engine hangers (Part No.: 12281-21010) then secure it with bolts (Part No.: 91642-81025) to a torque value of 40 Nm (408 kgf-cm, 30 ft. lbs.). The mechanics should remove the front suspension crossmember sub-assembly together with the power steering rack housing heat insulator and the No. 1 steering column hole cover sub-assembly. First separate the steering intermediate shaft before handling the power steering rack and pinion assembly while maintaining marks on its steering link and No. 2 bracket. Remove the steering turn pressure tubes on both sides by using Special Service Tool: 09023-38201 then disassemble the power steering rack and pinion assembly starting with tie rod ends and continuing to steering rack boot clips and clamps. The repair requires inspection of the power steering rack followed by installation of power steering rack housing oil seal, rack steering piston ring and power steering rack with correct torque specifications applied. The service will end with front wheels installation after applying pressure feed tube assembly and installing tie rod ends alongside steering rack end sub-assembly and check fluid levels until system bleeding is complete. Next step is to inspect for leaks before attaching the hood and exterior components.
