Front Axle Boots

[Chevyman_15237]

This might be far fetched... could there possibly be something in the grease that deteriorates these boots? My front knuckles still have the military gaa in them; when I grease the truck I have been using Castrol Pyroplex Blue. Just throwing it out there...

When I changed the boots on my m52a2 one was full of grease and one had grease in it but not running out this boot is fine and the over full one is needing replaced again . I plan to take them a part and clean the way excess grease out .
