From the symptoms of my truck I think the u-joints on the rear drive shaft are going on my '03 Cummins 4X4. Somebody on another forum sent me a link to this site...

Does anyone know anything about these? Are they any better than the stock drive shaft and replacement joints? Will they even fit my QC/SB?

 

Doesn't look like it.

 

I know that this particular drive shaft won't fit. But is there a one piece shaft that will fit an '03 QC/SB. If there is what are the benefits of going with one piece drive shaft?

Also what are the cons of using a one piece?

 

The one piece shaft eliminates the carrier bearing and one u-joint. Best thing to do is go to the Doghouse website, and call him. He will answer any questions you got. Great guy to deal with.
