hello out there to everyone , hunting season is almost here and i've put off servicing my front diff long enuff. my question is if i order marlins hd axle seals is it imperative that i still align the knuckles with the sst tool or can i get away with out it

.. i don't have one and do not know anyone around my area that might have one to borrow, did i mention that i am mathematically challenged

... i did the diff years ago and never did bearing preload or kept track how the shims went or how many etc

, just sorta banged it together and drove it, crappy handling and all

let me know what you all think thanx...
