Does anyone know the part # for the trans mount? I assume the engine mount uses the same part for all 3 - Ford DG9Z-6038-J

I did a quick test with my son and I'd say you are right based on what I am seeing. Does this much movement look normal to you for such a low rev? I did it in both reverse (first part of video) and then drive (second half). https://photos.app.goo.gl/Ma61BZ8GRe5GxmxX7

Thanks. Is there a way to test them while still in the car? There are 0 vibrations so I wasn't assuming it would be related to the mounts. Also forgot to mention the sound is coming from the rear of the car.

Hey All, I took my fusion in for preventative maintenance to get it ready to turn over to my 16 year old son to drive. The car had no issuesreally except for the PTU was overheating and disengaging during highway speeds so I paid a local shop to replace it with a brand new Ford part. After they did all the work after turning out of their parking lot I heard a "clunk" (it almost sounds like if you tap your hand on a wooden desk with a medium amount of pressure). I didn't think much of it but noticed every time I made a turn it was doing it (both directions). I brought the car back to the shop and they of course claimed it was nothing they did, but came back saying the driveshaft had serious signs of wear and needed to be replaced or resurfaced. I went with the rebuild option from a local driveshaft shop and that did not fix the issue. I brought the car back to them a third time and was told it sounded like something in the differential. Frustrated at this point (and the fact they wanted to charge me $5k for a new diff) I bought a used differential off ebay from a 20k wrecked vehicle and had another shop put it in. I got the car back, reprogrammed the RDU to the computer as recommended, and the clunking sound remained. Brought the car back to the second shop and they had it a month and called a Ford specialist that could not determine what it was outside of the viscous coupling appeared to be leaking oil and was bad. I went ahead and had them replace it and the clunking sound remains. At this point I don't have any more money to invest in the car and despite what everyone is telling me, I truly believe the issue has to be in the suspension somewhere that the first shop messed up. Here is what was done on the car from a maintenance perspective: -Brake pads replaced -Rotors replaced -PTU replaced with new ford part -Engine and acessory belts replaced (was making noise before this) -Original differential had fluid drained and refilled -Differential replaced (used 20k differential, was in good shape) -Viscous Couplin replaced -Transmission fluid drained and replaced The clunking sound typically happens once around the 2-3 shift and it only will occur if you are turning the steering wheel and start to straighten the car back out after a turn. If you go in a straight line the car will not making the clunking sound no matter what speed you give it. Highly frustrated at this point, not sure where else to go with troubleshooting and don't want to give up the car. Was thinking the sway bar bushing but just verified they are nice and solid. Ty for the help.

Thanks akirby, I was not aware that was the case and this helps explain the confusion. I called the dealership and they confirmed 3.36 so that confirms that. I guess my biggest question is why all the newer models of this part come with 3.51 instead of 3.36..

Morning, My 2014 Ford Fusion Titanium 2.0L has an axle code of 33 which I assume is a 3.36 ratio. The part of the differential is S-150-A and when I look for a replacement almost every single one is with a 3.51 ratio. Does anyone know if moving to a higher ratio will require an ECU reflash or will it be OK to swap in a 3.51 differential if my car was originally equipped with a 3.36? I know back in the earlier days this would throw the shifting off with the transmission and the speedometer, but not sure it is that big of a deal on a newer car. Also curious if anyone knows specifically which gear ratio this model/year car had as it seems to conflict online. Thanks for the help.
