Rear carrier bearing issue. How does this even happen?!

[Rot Box]

The other night after about 10 miles of driving. My newer Spicer carrier bearing popped out of the rubber housing as the driveshaft slide rearward nearly coming out of the t-case. The rubber surround is now destroyed How does this even happen? Has anyone ever heard of such a thing? I'm 100% certain that I didn't install the bearing incorrectly and the entire driveshaft bolted into place without any hesitation or binding.

My U-joints are good, the truck does not have a lift. The rear axle is not moving around or anything like that, and the t-case mounts are in great shape.

I bought another new Spicer bearing assembly and installed it. Everything went into place great, but I have not driven the truck yet because I'm worried about it happening again

There's the fixed plate on the crossmember that the U-plate (the one that wraps around the rubber) bolts to. Should there be anything else between these two pieces?

Sounds like a bad bearing from the start IMHO

That's the weird part is everything felt and looked great. Spicer should be a pretty good replacement compared to a lot of parts store bearing

I've had a bad moog balljoint for these trucks. Mistakes happen everywhere. Motor and trans mount ok? Was everything tight? Bushing on rear leafs good?

sh*t happens > years back I installed a brand spanking new hot water heater > bad out of the box.

Bad carrier bearing for sure. Just before I pulled the auto out of my 91 it spit the rubber out of a brand new carrier. Swapped it out on the side of the road in about 45 minutes.

these days the failure rate of new parts, even top name parts , is REALLY getting annoying It's got to the point where even my wife is tired of listening to me ***** about it I figure about one out of 6-8 new parts is crap out of teh box anymore, I don't care where you buy it from

I'll put some close to home miles on the new bearing and hope for the best. I guess it would have to be a crap bearing as everything else looks great. I just worry about the same thing happening again. Its not the $32 bearing that gets me its the fact I could be in the middle of nowhere next time it happens and dead in the water

Anyway thanks again everyone I appreciate the help

You are speaking the truth there! It actually depresses me, as somebody who has been wrenching since I was a kid working on lawn mowers, keeping the old iron alive and kicking. As well as poor-quality parts, it seems that nobody keeps any inventory any longer as well, and I live in a major urban area.
