Steering Gear: Testing and Inspection
INSPECTIONUNIT INSPECTION
Check components for wear, damage or other faults. Adjust or replace if necessary.
LIMIT
Make a measurements as follows. If it exceeds the specified service limits, adjust or replace.
NOTE:
When fixing the steering gearbox assembly in a vise, apply a wooden piece on the flange portion.
Rack shaft sliding resistance (Except for XV model):
Limit: 350 N (36 kgf, 79 lbf) or less
Left/right differential of sliding resistance: 20% or less
Rack shaft sliding resistance (XV model):
Limit: 333 N (34 kgf, 75 lbf) or less
Left/right differential of sliding resistance: 20% or less
RACK SHAFT PLAY IN THE RADIAL DIRECTION
Right-turn steering:
Service limit:
Direction (black arrow both directions): 0.4 mm (0.016 in) or less
Direction (white arrow both directions): 0.6 mm (0.024 in) or less
Left-turn steering:
Service limit:
Direction (black and white arrows both directions): 0.4 mm (0.016 in) or less
Condition:

P: 98 N (10 kgf, 22 lbf)
INPUT SHAFT PLAY
In radial direction:
Wear limit: 0.18 mm (0.0071 in) or less
Condition: P = 98 N (10 kgf, 22 lbf)
In axial direction:
Service limit: 0.27 mm (0.0106 in) or less
Condition: P = 20 - 49 N (2 - 5 kgf, 4 - 11 lbf)
TURNING RESISTANCE OF GEARBOX
1) Using the ST, measure the rotational resistance of the steering gearbox assembly.
Preparation tool:
ST: SPANNER (34099PA100)
Service limit (Except for XV model):
Maximum allowable resistance: 18.3 N (1.9 kgf, 4.1 lbf) or less
Difference between right and left rotational resistance: 20% or less
Service limit (XV model):
Maximum allowable resistance: 17.7 N (1.8 kgf, 4.0 lbf) or less
Difference between right and left rotational resistance: 20% or less
