i didn't notice any oil leaking and yea mine pretty much burns out up to 3rd gear as well and i have 9+ inches of rear tire with my IForge rims, i dont think its the extra grip that does it, but thats the thing i just dont know what it can be that makes such a loud thump or bang sound i mean you feel it hit pretty hard in the underbody or somewhere and when i lifted the car the Diff looked and felt really solid no play at all i even tried moving it with a crowbar and some leverage but nope no play at all. my other option or thought was that it could be the shaft center support that might be worn so it could have some kind of play in the shaft and when you give it power or shift it could bump but idk since it was covered up by the heat shield
