Which carrier? The cheapest.. Everyone is using the same bearing, and the housing is all aluminum. Actually one of the most important parts is the spacer tube between bearings. I've seen one company use muffler tubing, and when that crushes down on the end your axle will feel loose. TO fix that you will tighten it again, which side loads the bearings (exactly what they are NOT meant for) and you will blow them out. I would try the Lonestar cast carrier. They cast the part and then machine the surfaces, and the price is good, I've seen them and they are plenty strong enough. Call and ask about the middle spacer tube, and ask if it is hardened and will crush down. It's a nice part.
