Axle bearing kit

From what I've heard they are pretty good. I've heard you shouldn't let them sit without lube for too long and they're supposed to be better if your running back wheels with a lot of back space like I have on my mini tubbed duster. A friend of mine recomends 4 tac welds on the ring that holds the bearing in place as he's had a couple move on him (could have something to do with a 970hp hemi)
