Suspension:Vibration
THE VEHICLE HAS A VIBRATION WHILE DRIVING. * VIBRATION WHILE DRIVING ADD-ON PER HOTLINE TEST DROVE WITH CUSTOMER AND CONFIRMED A VIBRATION/HOP FEELING FROM THE REAR OF THE VEHICLE. THE CUSTOMER STATED HE HAS HAD THIS ISSUE SINCE HE BOUGHT THE TRUCK NEW. REFERRED TO HOT LINE REQUEST 117448862, SUBMITTED BY MIKE GREEN ON THIS VEHICLE. REVIEWED WITH MIKE GREEN ABOUT WHAT ALL STEPS HE HAS TAKEN, ELIMINATING THE NEED FOR ME TO CHECK THE ROAD FORCE BALANCE OF TIRES. HE FOUND THE ROAD FORCE BALANCE OF TIRES TO BE AT 11 ON BOTH FRONT TIRES, AND 10 AND 12 ON REAR TIRES. HE ALSO ELIMINATED THE NEED FOR ME TO ROTATE TIRES SINCE HE ALL READY DID THAT. HE SWAPPED TIRES FROM LIKE VEHICLES. I INSTALLED THE VMM AND VIBRATION ANALYZER. TEST DROVE VEHICLE WHILE MONITORING SCREEN, AND CONFIRMED THE DRIVESHAFT WAS NOT CAUSING THE ISSUE, BUT THE PROBLEM WAS IN THE WHEEL OR SUSPENSION AREA. USING TECHNICAL SUPPORT REQUEST 117448862, REAR SHOCKS WERE REMOVED AND TESTED. THE REAR SHOCKS WERE FOUND TO BE VERY SOFT AND VERY, AND COULD FEEL A DRAG FEELING ON REBOUND. REPLACED REAR SHOCKS AND HARDWARE AS REQUIRED. TEST DROVE VEHICLE WITH VIBRATION ANALYZER INSTALLED. THE VIBRATION DID NOT OCCUR AT LEVELS THAT WERE PREVIOUSLY SEEN. THE HOP THE FEELING IS SHOWING TO BE GONE. COMPARED TO LIKE VEHICLE. AND VEHICLE IS FOUND TO BE OPERATING AS DESIGNED AT THIS TIME. HOT LINE CONTACT.
