2002 Toyota Sienna Rack And Pinion Parts Q&A

• Q: How to disassemble the Rack And Pinion on 2002 Toyota Sienna?

  A: The Rack And Pinion assembly needs SST 09612-00012 as a vise clamp while using SST 09023-38200 to extract 2 turn pressure tubes with the removal of 4 O-rings. Record the positions of tie rod ends and rack ends before unlocking the associated lock nuts then remove both tie rod ends and lock nuts. A screwdriver should carefully loosen the clamps until the RH and LH clips along with rack boots and clamps become removable without damaging the boots. Use a screwdriver to loosen claw washers after which you can remove rack ends by holding the rack and pinion with a 24 mm spanner while using SST 09922-10010 following designated direction instructions. Use SST 09922-10010 to remove the rack guide spring cap lock nut, after which you should use a 21 mm hexagon wrench to take off the rack guide spring cap and rack guide spring and rack guide sub-assembly. Separate the rack housing cap together with the self-locking nut SST 09616-00011 while also taking off the dust cover and control valve housing and its assembly by noting the matchmarks followed by gasket removal. Address oil seal lip risks by wrapping vinyl tape to the serrated control valve shaft section before pushing the control valve assembly with oil seal to extraction and finally removing the oil seal. First pull out the rack housing No. 2 bracket and its grommet and after that turn the cylinder end stopper clockwise with SST 09631-10021 until the wire end becomes visible and then perform a counterclockwise rotation. First use a brass bar with a hammer to tap the rack and pinion before extracting the bushing and O-ring and pressing out the oil seal with SST 09950-60010 (09951-00290), 09950-70010 (09951-07360). Replace the oil seals and bearings if necessary through the use of SST 09950-60010 (09951-00250), 09950-70010 (09951-07200) while coating the new oil seal lip with power steering fluid before pressing it in. The replacement of two bearings requires SST 09950-60010 (09951-00260), 09950-70010 (09951-7200). Coat new bearings with molybdenum disulfide lithium base grease. To replace the oil seal from the bushing use SST 09527-20011 or 09612-24014 (09613-22011) while being cautious of NOT damaging the bushing and install new teflon rings and O-rings without harming the grooves. Place power steering fluid or grease on the parts before using SST 09950-60010 (09951-00240, 09951-00430, 09952-06010) to install the oil seal and double-check the proper orientation. Put the rack and pinion into place using SST 09631-33010 while using power steering fluid and extract the SST. Use a new O-ring while installing the bushing correctly in position then install the cylinder end stopper by aligning its wire installation hole. Test the air tightness using SST 09631-12071 to apply a vacuum pressure equivalent to 53 kPa. Install the rack housing No. 2 bracket together with grommet while ensuring matchmarks are lined up, then place the control valve assembly in position with special attention to avoid damaging teflon rings and oil seal. The service procedure requires installation of SST 09612-22011 oil seal first before attaching the control valve housing with its new gasket while torquing bolts to 18 Nm. Use SST 09616-00011 to install the self-locking nut at 25 Nm, followed by adding dust cover and rack housing cap where SST 09629-00017 sealant should be used before torquing to 59 Nm. Use the hexagon wrench to set total preload at 25 Nm before tightening and loosening the preload to match the specifications. Apply sealant to the rack guide spring cap lock nut before torqueing it to 50 Nm using tool SST 09922-10010 and reconfirm the total preload. The procedure concludes by torquing the RH and LH claw washers and rack ends to 60 Nm before installing the RH and LH rack boots with clamps and clips when the rack hole remains open. The installation of the 2 turn pressure tubes requires SST 09023-38200 for torquing to 12 Nm.
