DETAILED TEST D :

CONDITIONS

DETAILS/RESULTS/ACTIONS

CHECK FOR FRONT WHEEL BEARING ROUGHNESS

a. Raise and support the front end of the vehicle so that the front wheel

and tire assemblies can spin.
See GI group - lift support point.

b. Spin the front tires by hand.

● Do the wheel bearings feel rough ?
→ YES
Inspect the wheel bearings. Repair as necessary. Test the system for
normal operation.
→ NO
Go to

CHECK THE END PLAY OF THE FRONT WHEEL BEARINGS

Check the end play of the front wheel bearings.

● Is the end play OK ?

→ YES
Go toD3.

Go toD3.

→ NO
Adjust or Repair as necessary. Test the system for normal operation.

MEASURE THE LATERAL RUNOUT AND THE RADIAL RUNOUT OF THE FRONT WHEELS ON THE VEHICLE

Measure the lateral runout and the radial runout of the front wheels on the
vehicle. Go to detailed test C.

● Are the measurements within specifications ?

→ YES
Go toD4.

→ NO
Install new wheels as necessary and Balance the assembly. Test the
system for normal operation.

MEASURE THE LATERAL RUNOUT OF THE FRONT TIRES ON THE VEHICLE

Measure the lateral runout of the front tires on the vehicle. Go to detailed
test C.

● Is the runout within specifications ?

→ YES
Go toD5.

→ NO
Install new tires as necessary and Balance the assembly. Test the system
for normal operation.

MEASURE THE RADIAL RUNOUT OF THE FRONT TIRES ON THE VEHICLE

Measure the radial runout of the front tires on the vehicle. Go to detailed
test C.

● Is the runout within specifications ?

→ YES
Balance the front wheel and tire assemblies. If any tire cannot be balanced,
Install a new tire. Test the system for normal operation.

→ NO
Go toD6.

MATCH MOUNT THE TIRE AND WHEEL ASSEMBLY

Mark the high runout location on the tire and also on the wheel. Break the
assembly down and rotate the tire 180 degrees (halfway around) on the
wheel. Inflate the tire and measure the radial runout.

● Is the runout within specifications ?

→ YES
Balance the assembly. Test the system for normal operation.
