Solved 1 issue, and now another.

[Ryan2012F350]

Soooooo. 80000km on the ticker, now a new issue. Symptoms;

Shakes under moderate throttle. Whole truck shake not specific to wheel or seat.

Wide open no shaking.

Rolling in neutral no shaking.

Slowing in gear and on the brakes shaking.

Driving 50km/hr no throttle, no shaking.

Driving 50km/hr low throttle, shaking.

Ok so WTF is happening here??

I'm at a loss, I thought rear-end, torque converter, motor mounts, but none of this makes sense.

Searched and searched and it's way to vague...

Give me a list of what to check and I will check it. I have a 1800km one way trip up north coming up and need this truck in working order.

Thanks.
