Thanks Guys. Ya, looks or I mean sounds like the motor and tranny are coming out
I know what your saying about gear wobble or gear misalignment Nathan but it all looked fine when I first ran it with an open case. The 4:1 is the new version from PMD which bolts right up to the back of tranny.
I'm going to remove and test without it to eliminate that.
One thing I forgot to mention was the age of the stock motor. I bought this truck used. It had the old 56510 sound unit and old light kit so this thing might have many hours on it and the noise is the motor......
Oooppps, I think I just admitted to installing an old weak motor into my wife's new truck
.... Lol
Ok, I'm online buying a new motor RFN.....
