Ill start with back story. Just bought this used EXB Kraton. Was told from the get go by the guy selling it that he thought the rear diff was shot because the last time he ran it (August 2022), it seemed like it was only running front wheel drive. Finally yesterday i got it torn apart and found one of the spider gears has a couple broken teeth. So after many trips to my local hobby shop I’ve finally got the right parts on order. (Kept gettting wrong parts because I didn’t know about all the different model choices. This is my first hobby grade so i have no clue. LoL). So long story short i put it back together with just the front shaft in and ran it around at my office. (Holy poop even with half a drive train this things a blast.) I took some video so I’m hoping you guys can help with figuring out if something is out of alignment or its just its natural noise. Also heres some pictures of the shape the center diff was in. (Gross!!!)
