changing axel fluid?

yes. ...the fill hole on the front diff is a 10mm hex/allen. it's usually in there pretty tight ..so you may need to get a hardened socket. i twisted my cheap 10mm hex trying to get it loose.

and you can use synthetic without changing the seals.

 

i also found it helps to use a syringe on the rear. i got a real big one when my daughter was born it makes filling them alot easier.

Do the Rear Diff breather extension mod so your rear seals dont blow up like mine did and cost you 1000 bucks.

 

i think that's correct. ...just check your owners manual ..it tells you what to use.

I've never been through water. I think snow and ice buildup plugged mine. The breather is for the oil to expand and contract for temperature changes. Should have came extended from stock.
