• Q: How to service and repair the Rack And Pinion on 2000 Toyota Celica?

  A: Security and subsequent repair of the rack and pinion starts with a vise application of Special Service Tool: 09612-00012 to hold the Rack And Pinion assembly after which 2 turn pressure tubes are removed by Special Service Tool: 09633-00020. You should mark the tie rod end and rack end before starting to loosen the lock nut and taking off both tie rod ends and lock nuts from the sides. You should use needle nose pliers to open the wire before you remove the clips, wires and rack boots while protecting the boots then mark the RH and LH rack boots. To remove the rack ends use Special Service Tool: 09922-10010 directed by the provided illustration, while maintaining steady control of the rack and pinion by keeping it secure with a spanner and unstaking the claw washers with a chisel and hammer. The rack guide spring cap along with the conical spring washer and rack guide sub-assembly should be removed first before taking off the rack housing cap and O-ring. Lift out the control valve assembly before stripping off the cylinder end stopper with snap ring pliers. Then extract the rack and pinion and oil seal together with Special Service Tool: 09950-70010 (09951-07200) while avoiding any contact that may damage the rack and pinion. The rack housing remains protected from damage by using Special Service Tool: 09950-60010 (09951-00280), 09950-70010 (09951-07360) to extract the oil seal. A dial indicator should be used to check rack and pinion runout while inspecting its teeth wear and damage. Maximum rack and pinion runout should not exceed 0.1 mm (0.004 inch). The installer should use Special Service Tool: 09617-35020 to install the new bearing after applying molybdenum disulfide lithium base grease and torquing the bearing guide nut to 40 Nm (410 kgf.cm, 30 ft. lbs.). The correct installation method for new oil seals involves the following steps: use a screwdriver with vinyl tape to remove the old seal, apply power steering fluid to the new seal lip before inserting it with Special Service Tool: 09950-60010 (09951-00210, 09951-00340, 09952-06010), 09950-70010 (09951-07100) while maintaining proper seal orientation. Special Service Tool: 09612-20010 allows the operator to repeat the oil seal replacement process and to substitute bearings by using a brass bar for tapping out and in. Clean the rack housing first before installing new replacement union seats through the use of a screw extractor and a hammer. The teflon ring and O-ring replacement requires a screwdriver to safely remove them followed by power steering fluid coating of the new O-ring and expanding and installing the new teflon ring properly. The control valve assembly requires removal of its four teflon rings after which new rings must be expanded and then coated with power steering fluid before correct installation. Power steering fluid or Molybdenum disulfide lithium base grease should be applied to indicated parts during reassembly while Special Service Tool: 09631-20051 will help with steady installation of the rack and pinion. To install the oil seal properly use Special Service Tool: 09612-22011 to drive in the cylinder end stopper while testing for its air tightness with Special Service Tool: 09631-12071. Maintain zero vacuum during the test. Place the control valve assembly and the rack housing cap with new O-ring coated in power steering fluid then torque to 74 Nm (750 kgf.cm, 54 ft. lbs.). Install the rack guide sub-assembly together with the conical spring washer and rack guide spring cap by treating the cap threads with adhesive sealant. Total preload adjustment can be performed using temporarily installed RH and LH rack ends while torquing the rack guide spring cap to 25 Nm (250 kgf.cm, 18 ft. lbs.), followed by returning the cap to 12 degrees. By utilizing Special Service Tool: 09616-00010 you can turn the control valve shaft while loosening the rack guide spring cap until it stops working before tighten it for a preload range of 0.9 - 1.3 Nm (9 - 13 kgf.cm, 8.0 - 11.5 inch lbs.). Stake the cap in opposite locations and verify the preload once more after conducting these steps. Complete this procedure by installing RH and LH claw washers and rack ends while aiming for rack and pinion groove alignment before you apply 62 Nm (630 kgf.cm, 46 ft. lbs.) torque with Special Service Tool: 09922-10010 to secure the rack end and then stake the washer. Take care to prevent contact with the rack and pinion. Neuken and connect the RH and LH rack boots while securing the wires with clips to exit the clear rack and pinion hole before installing the RH and LH tie rod ends with their matching marks correctly set and tightening the nuts to 74 Nm (750 kgf.cm, 54 ft. lbs.). The procedure ends with the 2 turn pressure tubes secured by Special Service Tool: 09633-00020 and torqued at 20 Nm (200 kgf.cm, 14 ft. lbs.).
