What did you do to your NNBS GMT900 Tahoe/Yukon Today?

The right axle flange is pushed out of the housing. ???

HMM, well that's not right and would explain the fluid puddle, looks like it's been like that for a while has it been worked on by anyone? have you checked to see if it is full? i'm gonna guess it's not, if you remove the fill plug/bolt the fluid should be level with the hole

This is new. I was just under it less than a month ago doing the oil change. I inspected everything at that time. The diff is full and I check it regularly. The truck hasn’t leaked a drop since I have owned it. The front axle was out for service 40k ago by a dealer. I replaced that cv over a year ago. Thats all I know.

I am not sure if you can unbolt the axle and then smack that back in with a deadblow or not or if you have to pull that housing off and put back in that way. all the rebuild videos show it just going back in easy with the housing when reassembled
on this video he shows at 25min just hitting the one side with a dead blow
im confused on which part it is at 27 min he shows the other side just getting pushed on

edit I was looking at the wrong side

Yeah, I was just looking at this. It looks like there is a cir-clip that let go. I can try to knock it back but I might try getting that half off.

Based on this it looks like I will need to pull that side of the diff off. I wouldn’t trust that I git that clip right otherwise.

Rebuilding A GM 8.25 IFS Differential **56K Beware! Pic Heavy**

I am going to try to cover the basics on rebuilding the front differential in a GM truck with the 8.25" IFS differential. I am doing a gear change but also a full rebuild while I have it apart. Parts you'll need: Ring & Pinion Gear set, Master Install Kit, lock tabs (2)- (GM PN - 15588312)...

Looks like the culprit right here, I bet you can just dead blow it back in and be fine

I agree but am not sure if the clip is possibly broken.
