  1. Lift up the vehicle.
  2. Even if the location of leak can be easily found by observing the leaking condition, it is necessary to thoroughly remove the fluid from the suspected portion and turn the steering wheel from lock to lock about thirty to forty times with engine running, then make comparison of the suspected portion between immediately after and several hours after this operation.
  3. Cause and measure for oil leakage from "a"

    The oil seal is damaged. Replace the valve assembly with a new one.

  4. Cause and measure for oil leakage from "b"

    The torsion bar O-ring is damaged. Replace the valve assembly with a new one.

  5. Cause and measure for oil leakage from "c"

    The oil seal is damaged. Replace the valve assembly or oil seal with a new one.

  6. Cause and measure for oil leakage from "d"

    The pipe is damaged. Replace the faulty pipe or O-ring.

  7. Cause and measure for oil leakage from "g"

    The hose is damaged. Replace the hose with a new one.

  8. If leak is other than a, b, c, d, or g, and if oil is leaking from the gearbox, move the right and left boots toward tie-rod end side, respectively, with the gearbox mounted to the vehicle, and remove fluid from the surrounding portions. Then, turn the steering wheel from lock to lock about thirty to forty times with the engine running, and make comparison of the leaked portion immediately after and several hours after this operation.
    1. Leakage from "e"

      The cylinder seal is damaged. Replace the rack bush with a new one.

    2. Leakage from "f"

    There are two possible causes. Take the following step first. Remove the pipe assembly B from the valve housing, and close the circuit with ST.

    ST 926420000 PLUG

    Turn the steering wheel from lock to lock about thirty to forty times with the engine running, then make comparison of the leaked portion between immediately after and several hours after this operation.

    • If leakage from "f" is noted again:

    The oil seal of pinion & valve assembly is damaged. Replace the pinion & valve assembly with a new one. Or replace the oil seal and parts that are damaged during disassembly with new ones.

    • If oil stops leaking from "f":

    The oil seal of rack housing is damaged. Replace the oil seal and the parts that are damaged during disassembly with new ones.
