2003 F-150 FX4, I get a bad vibration while accelerating from a stop. It seems to be even worse when i'm on an incline. Could this be a torque converter problem?

could be a limited slip rear differential that needs service ....

Sounds like a u-joint, probably a dry cap. I had the same problem and found one of the u-joints was bad. Pulls away smooth now.

your drive shaft slip yoke might need to be lubed

clutches in the posi traction were worn out. Fixed seems just fine.
