CHECKING STEERING GEAR
-
Check gear housing and boots for looseness and damage.
-
Check gear housing and boots for fluid leakage. Refer to See: Testing and Inspection/Component Tests and General Diagnostics/Checking Fluid
Leakage.
-
Check connection with steering column for looseness.
-
Prior to removing the steering gear from the vehicle, check rack sliding force. Refer to "Checking rack sliding force".
-
If rack sliding force is not within specification, adjust rack sliding force. Refer to See: Adjustment Of Rack Sliding Force.
CHECKING STEERING LINKAGE
-
Check ball joint, and other component parts for looseness, wear, and damage.
CHECKING GEAR HOUSING MOVEMENT
1. Check the movement of steering gear housing during stationary steering on a dry paved surface.
-
Apply a force of 49 N (5 kg-f, 11 lb-f) to steering wheel to check the gear housing movement. Turn off ignition key while checking.
Movement of gear housing : ±2 mm (±0.08 in) or less
2. If movement exceeds the limit, replace or repair as necessary.
CHECKING RACK SLIDING FORCE
1. Disconnect steering column lower joint and knuckle arms from the gear.
2. Start and run engine at idle to make sure steering fluid has reached normal operating temperature.
3. Using a suitable spring gauge, pull tie-rod slowly to move it from neutral position to ±11.5 mm (±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check
that rack sliding force is within specification. Refer to See: Steering Shaft/Specifications/Steering Gear And Linkage.
