I agree.
However the carrier bearing is not usually asked to position the driveshaft or absorb thrust from braking or accelerating, this is the trouble. The front half of the shaft isn't anchored to anything except the bearing.

Is there any such thing as a "slip yoke eliminator kit" for a T5 transmission?
