• Q: How to service and repair the Rack And Pinion on 2001 Toyota Celica?

  A: Begin the rack and pinion maintenance by transporting the Rack And Pinion assembly to a vise through usage of Special Service Tool: 09612-00012 then extract the 2 turn pressure tubes using Special Service Tool: 09023-38200. Mark both tie rod ends and rack ends before releasing the lock nuts holding the RH and LH tie rod ends. Then remove the clips and wires along with the rack boots using pliers to prevent damaging any boots. Strike the claw washers open with a chisel and hammer in order to detach them from the rack and pinion while maintaining rack and pinion stability with a spanner during the removal process using Special Service Tool: 09922-10010. The rack guide spring cap along with its conical spring washer and rack guide sub-assembly must be removed first before moving on to take out the rack housing cap together with its O-ring. Using Special Service Tool: 09950-70010 (09951-07200) press the rack and pinion and oil seal out from the control valve assembly while avoiding the rack and pinion to drop. Use Special Service Tool: 09950-60010 (09951-00280) and 09950-70010 (09951-07360) to extract the oil seal from the rack housing while protecting its structure. Verify the rack and pinion for damage and wear by using a dial indicator to check runout levels that should not exceed 0.1 mm (0.004 inch). Install the new bearing through Special Service Tool: 09617-35020 and apply molybdenum disulfide lithium base grease to it. Secure the bearing guide nut to 40 Nm (410 kgf-cm and 30 ft. lbs.) torque specification. Install the oil seal with proper power steering fluid application onto the new oil seal lip before placing it correctly. Install new 2 union seats and teflon ring and O-ring while being careful to prevent damaging their grooves. Install the rack and pinion by using Special Service Tool: 09631-20051 while applying power steering fluid or grease to the indicated parts and correctly installing the oil seal. Position the cylinder end stopper next and place a new snap ring on its position. For the air tightness test use Special Service Tool: 09631-12071 to apply a vacuum pressure of 53 kPa which corresponds to 400 mm Hg and 15.75 inch Hg for a duration of 30 seconds. The control valve assembly should be installed with care to protect teflon rings and oil seal lips and then the rack housing cap can be installed along with a new O-ring which requires 74 Nm (750 kgf-cm, 54 ft. lbs.) torque. Install the rack guide sub-assembly together with a conical spring washer and rack guide spring cap while using sealant on threads. You can determine the total preload by putting in temporary RH and LH rack ends, torquing the rack guide spring cap to 25 Nm while returning it 12 degrees. Use Special Service Tool: 09616-00011 to tune the control valve shaft while using it to loosen the rack guide spring cap until spring operation stops and then tighten it to produce 0.9 - 1.3 Nm of preload (9 - 13 kgf-cm, 8.0 - 11.5 inch lbs.). Use the tool 09616-00011 to stake the rack guide spring cap before performing another preload check. Mount the RH and LH claw washers along with rack ends into position so the claws match rack and pinion grooves before tightening the rack end to 62 Nm (630 kgf-cm, 46 ft. lbs.) using Special Service Tool: 09922-10010 and staking the washer. Put on the RH and LH rack boots followed by wires and clips before mounting RH and LH tie rod ends and secure the lock nuts through alignment of matchmarks while tightening the nuts to 74 Nm (750 kgf-cm, 54 ft. lbs.). Users need to install 2 turn pressure tubes using Special Service Tool: 09023-38200 while torquing them to 23 Nm (230 kgf-cm, 17 ft. lbs.).
