remove both tires
pop the upper ball joints on each spindle.
disconnect the driveshaft
remove the front right caliper
disconnect the right side shock from the LCA
next is to pull out the CVs they are clipped in and after some effort you can pry and then slide the Passanger CV out all the way and leave it.
on the drivers side you can pop the CV loose but it wont come all the way out of the diff becuse of clearance. this is ok. if you have a friend invite him over cause you will need help.
the diff is bolted up in 3 places. 2 above the diff and one on the driverside which is like 3bolts in the side of the diff and one on the frame.(some type of bracket)
as you are wiggling the diff out have a buddy slide the rest of driverside CV out. the diff should come out now. its HEAVY so becareful.
from there you should beable to fix what you need.
btw most use a pump to get the old oil out
