TSB #: 19-SS-003H Page 2 of 4 SUBJECT: PALISADE (LX2) AWD VIBRATION SUBJECT: 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. TSB #: 19-SS-003H Page 3 of 4 SUBJECT: PALISADE (LX2) AWD VIBRATION SUBJECT: 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. TSB #: 19-SS-003H Page 4 of 4 SUBJECT:
