SERVICE PROCEDURE FLOW CHART
Vehicle in dealer for
vibration related complaint.

Set cold tire pressure. Test drive 20 minutes at freeway
speeds to warm up tires. Evaluate vibration.

Yes

Check road force variation (RFV)
immediately after test drive (warm tires).

Potential to reduce
assembly RFV or
improve dynamic
balance?

No

Vibration present
from 60-70 mph?

No
Service complete

Arrange wheel/tire
assemblies by RFV
values.

No
Yes

Perform force-matching to
reduce RFV. Balance
assemblies if necessary.

Service complete

Test drive 20 minutes
at freeway speeds.
Vibration still present?

Yes
Replace prop shaft & AWD
coupler.

Service Procedure Notes:

NOTICE
When performing the test drive, take care to evaluate the vibration under the following
conditions:




Take careful notes of the customer’s specific driving condition (speed, throttle
application, road condition, etc.) to evaluate as close to their experience as possible.
Evaluate at constant speed using cruise control set to 65 mph.
Evaluate applying light throttle on and off starting at 60 mph, gradually reaching 70 mph.

NOTICE

Driver Side



Perform force-matching on any tire/wheel assemblies that show potential to minimize
RFV values.
Arrange wheel/tire assemblies according to RFV value as shown below:
Front Left:

Front Right:

Lowest RFV

2 lowest RFV

Rear Left:

Rear Right:

3 lowest RFV

Highest RFV

nd

rd



Passenger Side



Record the BEFORE and AFTER RFV values of each of the four (4) tire/wheel
assemblies on the R.O.

NOTICE
If vibration condition is not resolved after optimizing wheel/tire assembly RFV, replace the
propeller shaft and AWD coupler assemblies together. Refer to the shop manual for service
procedures.
