Passenger side axle leak.

Put new outer axle on my 93 yj and now it leaks. Guy at the auto parts store said that I have to remove the axles and the locker and replace the seals inside the pumpkin. Isn't there a seal the vac disconnect area? The guy at the parts store said "the one there doesn't stop oil, it just stops dirt". True or not? Doesn't the vac disco have to be lubed to slide?

He is probably thinking of the plastic disk on the far outboard end of the axle tube that does nothing

Unless you swapped to TJ shafts you have a seal on the outboard side of the diconnect housing, for the pass side. The drivers side seal is inside the pumpkin.

On the passenger side of a YJ's HPD30, the axle seal is located on the outer side of the vacuum disc housing.

Yes, the vacuum disco gets it's lubrication from the diff fluid.

The parts guy is mistaken. He's probably thinking about other types of D30 housings which do have the passenger side axle seal internal to the housing.
