I have the front end apart on my old 12 valve and have been told the axle seals have to have a good seal for the vacuum motor to kick it into 4x4------This sounded awful far fetched to me.The axle shafts have a fair amount of wear but just in the seal area and before I started going back togethor I needed some input---------Thanks in advance

 

ive never once herd the seals have to be good for the actuator to work because i got mine to work when i had the hole entire axle in pieces last weekend if that were true than i wouldnt have 4x4 now since one of my acle seals is bad now

 

Simply not true about the axle seals.
