Hi all,
Recently I swapped my 3.15 diff for a 3.55. At the same time i put on the steeda subrfame bushing kit and red diff inserts.
At the drive noticed a strong resonance exaclty at 30mph. It was present only on slight or strong acceleration.
The shop changed the motorcraft diff oil for a bardhal and the resonance got 50% better.
Got to a road race track for some hours and coming to home the resonance get even worse and present up to 60mph. Raising the speed it becomes more acute. I searched on youtube something and I can say it is not a exactly a gear whine, but behind the reconance there is something “metallic”.
Help me!! :frusty:
