Summary
THIS PRELIMINARY INFORMATION COMMUNICATION PROVIDES INFORMATION TO THE TECHNICIAN ON THE STEPS TO DIAGNOSE AND REPAIR VEHICLES THAT HAVE A RESONANCE TYPE VIBRATION OCCURS BETWEEN 40 TO 60 MPH. IN MOST CASES THE ENGINE MUST BE UNDER A SLIGHT LOAD SUCH AS A/C COMPRESSOR ENGAGEMENT, LIGHT THROTTLE, AND IN 6TH GEAR TORQUE CONVERTER CLUTCH APPLIED. TECHNICIAN WILL RELAX THE ENGINE AND TRANSMISSION MOUNTS, THEN THE EXHAUST SYSTEM BY LOOSENING THE FRONT PIPE STUDS. ALSO WORK DOWN THE SYSTEM DISCONNECTING ONE EXHAUST HANGER AT A TIME. THEN TAKE THE VEHICLE ON A TEST DRIVE TO VERIFY THERE WAS IMPROVEMENT. IF ADDITIONAL STEPS ARE REQUIRED PLACE TWO SETS OF EXHAUST DAMPENERS ONE SET BEFORE AND ONE SET AFTER THE FRONT CATALYTIC CONVERTER. IT MAY BE REQUIRED TO MOVE THE PAIR OF DAMPENERS ALONG THE EXHAUST SYSTEM TO GET THE BEST RESULTS.

Summary
This Preliminary Information communication provides information to the technician on the steps to diagnose and repair vehicles that have a resonance type vibration occurs between 40 to 60 MPH. In most cases the engine must be under a slight load such as Air Conditioning compressor engagement, light throttle, and in 6th gear Torque Converter Clutch applied. Technician will relax the engine and transmission mounts, then the exhaust system by loosening the front pipe studs. Also work down the system disconnecting one exhaust hanger at a time. Then take the vehicle on a test drive to verify there was improvement. If additional steps are required place two sets of exhaust dampeners one set before and one set after the front catalytic converter. It may be required to move the pair of dampeners along the exhaust system to get the best results.

Please discard PIP5277 A. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this Pl. Condition/Concern Some customers may comment that a resonance type vibration occurs between 40 to 60 MPH. Bulletin No.: PIP5277B Date: Jun-2016 In most cases the engine must be under a slight load such as NC compressor engagement, light throttle, and in 6th gear tee applied. It also is described as a 2nd order engine boom or vibration. In most cases this is an inherent condition on 4 cylinder models, however in some cases this condition is much more amplified. Recommendation/Instructions Relax engine and transmission mounts, then the exhaust system by loosening the front pipe studs. Work down the system disconnecting one exhaust hanger at a time. Test drive to verify any improvements. If additional steps are required place two sets of exhaust dampeners (part #10199232 and attach with 2 1 /2″ exhaust clamps, part #15595206) one set before and one set after the front catalytic converter. It may be required to move the pair of dampeners along the exhaust system to get the best results (photos attached). This repair will only improve noise and vibration to a condition comparable to like vehicles with the 4 cylinder powertrain. Fabricate 2 dampers using the following procedure: 1. Obtain 4 dampeners, Part Number 10199232. 2. Line up 2 dampeners so the dampener pipes are opposite of each other. 3. Line up one mounting hole from each dampener with the holes of an appropriate size exhaust clamp. 4. With all of the holes lined up, weld the flat portion of the dampeners together and to the flat part of the exhaust clamp 5. Attach the dampeners to the exhaust system using exhaust clamps. Warranty Information For vehicles repaired under warranty use: Labor Operation Description Labor Time 4050272 Exhaust System Alignment Use Published Labor Operation Time Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
