trans contacting floor board under heavy throttle

[nation]

over the past few weeks ive noticed that under heavy throttle the rear flange on my trans contacts my floor board,and i cant figure out whats broken. could the carrier bearing be worn out causing the extra play? tranny mount bad? im open to suggestions.

I'd think a broken trans mount first....

My 99 did the same thing-replaced motor mounts, trans mount, still the x-fer case hit the floor-the driveshaft flange actually rubbed the body! I ended up replacing all the body mounts to fix it.

my carrier bearing looks like its shot.im going to change that and my tranny mounts. im trying to find a poly-style mount for the tranny.

My t case twists and slaps the floor boards under heavy throttle to and when I'm letting the clutch out I did the Trans mount wasn't it. I'm about to do the clutch and figure ill do the motor mounts while I'm under there. How bad of a job is it or any important tips from anyone whose done it?

Mine does the same thing, the trans actually lifts up under acceleration, its alo caused by the axle wrap on these lifted trucks.My Problem was the crossmember comes loose, no matter how tight i torque it down, hard acceleration will cause it to shift. Doesnt hit the floor but makes a nasty clunk
