Well driving without something that is supposed to be there is never a good idea.. I would say yes... although I wouldn't rip it out just cause its rotting away leave it alone until you get the new one..

 

And if its already making a problem than don't drive on it because you will be getting into u-joint trouble in no time than maybe drive shaft issues

I know someone just filled the cracks with RTV and let it set up, though I can imagine that'd take a few tubes.  Another way was to remove the rubber and wrap the outer bearing with strips of soft rubber, like an old inner tube, then clamp it down with the bearing retainer.  Both of those of course assume the bearing itself is still functional.

 

If the bearing is shot, or you keep driving with it flopping around, you may find your truck attempting to pole-vault with the driveshaft.  It doesn't do that very well.

Can't guarantee the success of this, But I  was once told by an acquaintance, when talking about these trucks and the carrier bearings, that he wrapped a section of RUBBER ( not plastic!) garden hose around his carrier bearing to get home 200 miles away from where it started rattling.....It worked well enough to get him home and get a new bearing in it.

Carrier bearings almost NEVER go bad. It's ALWAYS the rubber doughnut isolator that rots away and without support the driveshaft is unstable and flops around in the cage.

 

I used an inch wide strip of rubber conveyor belt wrapped around the stationary part of the bearing and clamped down by the U shaped holder. Rubber garden hose is an even better idea! As long as the rubber is trimmed to the correct length (by trial and error) and fits FIRMLY in place it will work.

 

Mine was just a quick fix with the intention of swapping in a used but good spare.....  but never did because it worked so well. Drove it for over 2 years and across Canada and back.

I know it's too late, but I used the same method some others had mentioned, to drive around temporarily until my replacement came in the mail. I used a couple sections of bicycle innertube, and folded them into little squares, and wedged them around the stationary part of the carrier bearing. They were held in place with rubber cement. This worked for about a week, when I noticed a piece of it laying on the ground under my truck. The replacement came in the mail that day anyway.
