Carrier Bearing failure
 

So, I have had the carrier bearing mount to fail 3 times. It is breaking where the mount becomes the "T". Why is this happening????

Unbalanced?
Make sure the yoke ujoint is lined up right.
Just guesses...

Check to make sure your slip joint is not bound up.

Did you adjust the pinion angles after lowering?

First off is your truck lowered (or lifted)?
Half ton with coils?
HD suspension listed on the SPID?

The link posted pertains to your problem. Read post 21 where I explain my theories on why these failures occur.

If you have more questions i will attempt to answer them.

There should be some front to back adjustment where it mounts. Make sure your truck is at ride height when tightening these bolts. Too far either way will cause extra stress when the suspension is fully compressed, or extended.
