• Q: How to reassemble the power steering rack and pinion gear on 2008 Toyota Corolla?

  A: The procedure for power steering rack and pinion assembly requires application of power steering fluid or molybdenum disulfide lithium base grease onto the marked components. Start the power steering control valve lower bearing installation process with tools 09950-60010 and 09951-00220 accompanied by Special Service Tool: 09951-00220 as well as a press device. You must install the power steering cylinder tube oil seal by facing the right direction following the directions from Special Service Tool: 09950-60010, 09951-00240 and a press. Install the rack and pinion by using Special Service Tool: 09950-60010, 09951-00400 and a press to position the power steering rack bush and oil seal after carefully expanding the power steering fluid-coated oil seal. Drive in the cylinder end stopper through Special Service Tool: 09612-22011 before installation of a new snap ring. Place the rack and pinion under vacuum to check for any leakages. Install the power steering control valve upper oil seal and bearing through Special Service Tool: 09950-60010, 09951-00180 along with a press while maintaining the correct orientation. Put power steering fluid into the control valve rings before positioning them in place and putting Special Service Tool: 09631-20081's tapered portion above the rings. Apply power steering fluid to the new oil seal lip before installing it using Special Service Tool: 09612-22011, 09616-00011. To complete the procedure install a new gasket between parts and bolt the valve housing onto the rack housing at 18 Nm torque. First fit the rack guide along with its compression spring then coat the rack guide spring cap threads with sealant before placing it temporarily in its position. To check total preload position the rack ends temporarily then apply torque to 25 Nm on the rack guide spring cap before backing off the nut to fine-tune the preload settings within the specified range. Install the rack and pinion end sub-assembly using special service tool 09922-10010 with focus on keeping the rack and pinion hole free from any obstruction. Insert rack boots numbers 1 and 2 with silicon grease application while using special service tool 09521-24010 to install boot clamps. The last procedure includes installing tie rod end sub-assemblies following matchmark alignment before adding right and left turn pressure tubes with new O-rings which require a 12 Nm torque using Special Service Tool: 09023-38201.
