3) Install grommet (1) whose projection (2) orients vehicle forward.
4) Install front suspension frame with steering gear case assembly referring to “Front Suspension
Frame, Stabilizer Bar and/or Bushings Removal and
Installation in Section 2B”.Steering Rack Boot InspectionS7RS0B6306007
Hoist vehicle.
Inspect each boot for tear. A torn boot allows entry of
dust and water which can cause wear to steering rack
and pinion to produce noise as well as rust to result in
malfunction of steering system.
Even if boot tear is small, replace with new one.
Also, check each boot for dent. If there is a dent, keep
boot in most compressed st ate for some seconds to
correct dent.
Boots should be visually inspected for any damage, dent
and tear during every periodical inspection at specified
intervals and whenever vehicle is hoisted for any other
purpose.
Tie-Rod / Rack Boot Removal and InstallationS7RS0B6306008
Removal
1) Remove steering gear case assembly referring to
“Steering Gear Case Assembly Removal and
Installation”.
2) For ease of adjustment after installation, make marking (1) of tie-rod end lock nut position of tie-rod
thread.
3) Loosen tie-rod end lock nut and remove tie-rod end.
4) Remove boot band (2) and clip (1).
5) Remove boot from tie-rod.

0.5 kgf-m, 3.7 lb-ft)
Torque Sensor and Its Circuit InspectionS7RS0B6306012
1) Remove console box.
2) With ignition switch turned OFF, connect scan tool to DLC or connect voltage tester between “E52-18” –
“E52-9” (main sensor) or “E52-6” – “E52-9” (sub
sensor) with connected connector (1) to P/S control
module. 3) Set torque wrench to stee
ring wheel referring to
“Steering Force Check” for checking steering force.
4) Turn ON ignition switch without engine running and select scan tool “Data list” mode due to check of
“TQS Main Torque”, “TQS Sub Torque” and “Assist
Torque” display on scan tool when steering wheel
turned left and right (if used).
5) Check that characteristic of torque sensor (main and sub) output voltage or scan tool data and steering
force is as following graph when steering wheel is
turned left and right. If sensor voltage or scan tool
data is out of specified value or does not vary linearly
as the following graph, check P/S control module
and its circuit.
If they are OK, replace steering gear case assembly.
