You don't put oil in the knuckles <img src="/forums/images/graemlins/zombie.gif" alt="" /> , you put a small amount of grease for the upper and lower trunion bearings but no oil...

As for the BFEKit, its alright, but i've heard alot more bad than good and its only stock d44 strenght, bobby's new stuff puts you up there with stock d60 35spline stuff...

Example, the inner axles are nearly the same OD as the oil seal on the axle, they are friggin beeeeffy....I'll getcha some good wheelin pics this weekend smile
