OEM 2004 Toyota Corolla Rack And Pinion

2004 Toyota Corolla Parts Questions & Experts Answers

• Q: What Are the Proper Steps, Required Tools, and Torque Specifications for Removing, Overhauling, and Reinstalling the Power Rack And Pinion Assembly on 2004 Toyota Corolla?

  A: The installation requires coating the parts marked by arrows with power steering fluid or molybdenum disulfide lithium base grease. First disconnect the negative terminal of the battery then check the center front wheel while removing the horn button assembly and steering wheel assembly by using SST 09950-50013 (09951-05010, 09952-05010, 09953-05020, 09954-05021). Disconnect the tie rod end sub-assembly LH by removing its cotter pin and nut then using SST 09628-62011 to separate it from the steering knuckle. Start by removing the front wheels and both engine under covers. Repeat for the RH side. Begin by taking off the column hole cover silencer sheet and proceed with disconnecting the steering intermediate shaft through SST 09023-38400 before moving onto the pressure feed tube assembly then return tube sub-assembly. First disconnect both front stabilizer link assemblies then separate the lower sub-assemblies of front suspension arm units from their left-hand and right-hand sides. You should first detach the hood sub-assembly, cylinder head cover No.2 while suspending the engine assembly by installing the two engine hangers (No.1 engine hanger: 12281-22021, No.2 engine hanger: 12281-15040, Bolt: 91512-B1016, Torque: 38 Nm). The front suspension crossmember sub-assembly requires removal by disconnecting it from the engine mounting insulator FR and the frame which can be supported by a transmission jack before removing the bolts. Start your procedure by detaching No.1 steering column hole cover sub-assembly and its components including steering intermediate shaft and rack and pinion power steering assembly using full bolt removal. Dismount the left and right turn pressure tubes with SST 09023-38200 before removing the O-rings when the rack and pinion power steering assembly sits in a vise that uses SST 09612-00012. Check the torque specifications of LH and RH tie rod end sub-assemblies after their removal. SST 09922-10010 helps users uninstall the steering rack end sub-assembly after they remove both steering rack boots No.1 and No.2 by clearly marking the RH and LH rack ends. Begin by removing the rack guide and power steering control valve and their neighboring components to check for damage and wear on the power steering rack. The new bearings receive proper positioning and receive required lubrication during integration. Sealants and torque requirements should be used during reassembly of the power steering control valve and rack assembly. Reinstall the steering rack end sub-assemblies to the steering rack hole before placing steering rack boots. The technician will combine the tie rod ends with engine under covers and front wheels before inspecting the center front wheel and adjusting steering wheel alignment. After power steering fluid addition and system bleeding you need to check for any signs of leakage then replace the cylinder head cover No.2 along with the hood sub-assembly while making necessary adjustments and achieving correct wheel alignment and SRS warning light operation.
