You'd know if you had the joined pulled apart cause they wouldn't sit right. Take off the CVS if you're concerned
TBH pulling the front diff is an easy job.
Take off your front skid plate
Disconnect breather, actuator, drive shaft, cv axles.
Loosen and unscrew.but don't fully remove the nuts securing your center link to the pitman arm and idler arm, note the orientation. Toss a 2 jaw puller on it, load it up nice and tight, then smack it with a hammer. Once that's free, swing it down and front to get clearance.
3 mounting boots to remove the diff. It swings down, then you turn it and it drops out. It's fairly light, no more than 80lbs give or take.
Doesn't take more than 2 hours to do. Longest part is getting the tapers out of the center link without a pickle fork, which would mess up the ball joint boots.
