• Q: How to disassemble the Rack And Pinion on 2004 Toyota Land Cruiser?

  A: Secure the Rack And Pinion assembly inside a vise with SST 09630-00014 (09631-00142) through care not to clamp too tightly for disassembly of the rack and pinion. Start by using SST 09023-38200 to remove the two turn pressure tubes followed by loose clamping of the rack boots with pliers while marking the RH and LH sides. Afterward, discard the clips together with rack boots and clamps. Using a screwdriver along with a hammer to stake back the washer while avoiding the rack and pinion. Then guide steered rack end removal by a spanner while using SST 09922-10010 and following the correct direction. Use SST 09922-10010 to eliminate the rack guide spring cap lock nut along with the claw washers while withdrawing the rack guide spring cap combined with the rack guide spring and rack guide sub-assembly until the dust cover appears. To handle the control valve housing with control valve assembly, make matchmarks then untighten the two bolts, pull out the assembly while removing the O-ring. The valve assembly should be tapped out using a plastic hammer on the control valve shaft after applying vinyl tape and using SST 09631-20060 to loosen the bearing guide nut while taking care not to damage the oil seal lip. Before removal of the valve assembly components begin, replace the SST 09922-10010 to extract the cylinder end stopper along with its O-ring. Precise use of SST 09950-70010 (09951-07200) press extracts the rack and pinion and oil seal while preventing the rack from falling out and finally removing the oil seal. Examine the rack and pinion for deformation and wear before inspecting the bearing for damage while lubricating it with molybdenum disulfide lithium base grease. Install the oil seal according to direction specifications using SST 09950-60010 (09951-00260) and 09950-70010 (09951-07150). The bushing requires an inspection for cracks while operators should grease it when replacement is required. After inspecting rack and pinion grooves for damage you must install Teflon rings together with O-rings which have been treated with power steering fluid. Replace the Teflon rings in the control valve assembly while taking care to prevent damage to the grooved area. A screw extractor proceeds to disassemble the control valve housing union seat so you can softly tap the new one into position. To rebuild the unit use power steering fluid or molybdenum disulfide lithium base grease on the indicated components before using SST 09631-00350 to install the rack and pinion and applying more power steering fluid before rack housing insertion. Put SST 09631-00350 to use for installing the oil seal in the correct direction before adding spacer and cylinder end stopper via power steering fluid application to new O-rings followed by stopper insertion with a wooden block. Subject the air tightness test using SST 09631-12071 by maintaining 53 kPa vacuum pressure for 30 seconds. Before installing the control valve assembly you must cover Teflon rings and protect the oil seal lip before using SST 09631-20060 to tighten the bearing guide nut. After proper alignment of matchmarks between the valve assembly and control valve housing the technician torques all bolts. The rack guide sub-assembly should be installed alongside its dust cover, rack guide spring, and rack guide spring cap while attaching sealant to the cap threads. The technician follows this procedure to adjust overall preload by first installing the rack ends and torquing the rack guide spring cap while using SST 09616-00011 to reach necessary preload settings. Apply sealant to the rack guide spring cap lock nut before checking the total preload for a second time before installing the RH and LH claw washers and rack ends along with staking the washers and torqueing them with SST 09922-10010. Install the RH and LH rack boots followed by clamps, clips and pressure tubes using SST 09023-38200 while torquing them to 23 Nm.
