I'm running Precision 464's. I like Precision, but can't point to any specific reason why.
On edit - oh, you mean the drive shaft, not the axle shafts. Sorry, the 464 is for the axle shaft. I've got Precision 254 and 234 "Super Strength" joints ready to go when my factory ones fail. The Super Strength models are nice, because the grease fitting is in one of the caps (where it ought to be!).
When you install them, remember to pump them with grease until it oozes from ALL 4 caps.
