• Q: How to Service and Repair a Rack and Pinion Steering Gear on 2000 Toyota Echo?

  A: The manual rack and pinion assembly needs to be set in a vise using Special Service Tool: 09612-00012 but be cautious not to stretch the rack and pinion. Service the rack and pinion by first placing matchmarks on the tie rod ends then gently loosen the lock nuts to detach them with the right and left hands respectively. Liberate the right-hand and left-hand clips and clamps and rack boots by first loosening the clamp with pliers and then carefully extracting the clip and clamp with the boot intact while maintaining proper markings for both rack boots. First stabilize the rack while using Special Service Tool: 09922-10010 to unfasten the right-hand and left-hand rack ends. The rack guide spring cap lock nut should be removed first through Special Service Tool: 09922-10010 followed by successive removal of rack guide spring cap, rack guide spring spacer, conical spring washer, rack guide spring and rack guide sub-assembly. To eliminate the oil seal and spacer from the rack housing use a screwdriver covered with vinyl tape while carefully preventing damage to the housing before using snap ring pliers to detach the snap ring which lets you extract the pinion without harming serrations on its surface. Revolution of the rack must be avoided to prevent bushing damage when performing removal. A dial indicator helps check the rack for runout as well as teeth wear and damage by ensuring maximum runout stays below 0.15 mm (0.0059 inch). The inspection should also include examining the back surface for wear and damage. The indicated parts should receive a coating of molybdenum disulfide lithium base grease before installing the rack through the pinion side without rack revolution while setting its notched side toward the pinion. Position the pinion while pushing it forward then apply snap ring pliers to install the snap ring followed by the spacer and greased new oil seal before tapping it in using Special Service Tool: 09517-12010 and a hammer.
