• Q: How to service and repair the Rack And Pinion on 2003 Toyota Celica?

  A: Start rack and pinion service by mounting the Rack And Pinion assembly in a vise using Special Service Tool: 09612-00012 yet avoid tightening it too forcefully. The removal of 2 turn pressure tubes can be accomplished using Special Service Tool: 09023-38200 followed by the marking and removal of RH and LH tie rod ends along with their lock nuts. Use needle nose pliers to loosen the wire while you remove clips wires and rack boots from the system. Protect the boots during this process. To remove the rack ends and steering rack the operator uses Special Service Tool: 09922-10010 while following the correct removal direction while holding the rack with a spanner and striking the claw washers with a chisel and hammer. Drop the rack guide spring cap, conical spring washer and rack guide sub-assembly and after that remove the rack housing cap with its O-ring. Pull the control valve assembly from its position before removing the cylinder end stopper with snap ring pliers. Use Special Service Tool: 09950-70010 (09951-07200) to extract the steering rack before extracting the oil seal through Special Service Tools: 09950-60010 (09951-00280), 09950-70010 (09951-07360) while protecting the rack housing from damage. Maximize runout of the steering rack should not exceed 0.1 mm (0.004 inch). Additionally check for damage and tooth wear and rack runout. The new bearing requires application of molybdenum disulfide lithium base grease using Special Service Tool: 09617-35020 before installation via the same tool to 40 Nm (410 kgf-cm, 30 ft. lbs.) torque. Apply power steering fluid to new seals before inserting them into place using Special Service Tool 09950-60010 (09951-00210, 09951-00340, 09952-06010) or Special Service Tool 09950-70010 (09951-07100). These tools will ensure the correct orientation of the seal. Special Service Tool: 09612-20010 should be utilized for additional replacement of oil seals while inspecting the rack housing for damage. The technician should remove and replace any damaged bearings by tapping them out with a punch then hammer while installing a fresh bearing which requires grease application. The 2 union seats can be exchanged by using a screw extractor followed by gentle tapping of new ones into place. Apply power steering fluid onto the new O-ring before mounting while avoiding damage to the groove of both the teflon ring and O-ring from the rack and pinion. Install the 4 new teflon rings of the control valve assembly by coating them with power steering fluid. After expansion, put each ring into place with caution. Reassembly requires power steering fluid and grease application to indicated parts before rack and pinion installation with the use of Special Service Tool: 09631-20051. The oil seal must be installed with proper orientation during this process. Drive in the end stopper of the cylinder through Special Service Tool 09612-22011 and follow by installing a new snap ring. Test the air tightness with Special Service Tool: 09631-12071 over a period of 30 seconds while maintaining 53 kPa vacuum pressure equal to 400 mm Hg or 15.75 inch Hg, to verify vacuum stability. After performing an inspection for teflon rings and oil seal lips damage, the control valve assembly can be installed with the rack housing cap containing new O-ring lubricated by power steering fluid that should be torqued to 74 Nm (750 kgf-cm, 54 ft. lbs.). Position the rack guide sub-assembly with conical spring washer and rack guide spring cap on the threads along with sealant application. Total preload adjustment requires a temporary installation of RH and LH rack ends while torquing the rack guide spring cap to 25 Nm (250 kgf-cm, 18 ft. lbs.) followed by returning it to 12 degrees then using Special Service Tool: 09616-00011 to adjust the control valve shaft. After checking recheck the preload by installing the RH and LH claw washers and rack ends and torquing to 62 Nm (630 kgf-cm, 46 ft. lbs.) with Special Service Tool: 09922-10010. After ensuring clean rack and pinion openings, add the RH and LH rack boots, wires along with clips before installing tie rod ends with lock nuts while adjusting toe-in before torquing these parts to 74 Nm (750 kgf-cm, 54 ft. lbs.) and finally adding 2 turn pressure tubes with a torque of 23 Nm (230 kgf-cm, 17 ft. lbs.).
