Building my car and the rear diff definitely has a spot where it hits resistance, not spinning freely. Same spot every rotation of the diff bevel gear, there is resistance. Its not the bevel gear itself though, teeth look fine.
Should I not worry about it now and it will break in with some use and not have that resistance anymore, or is there something else inside the diff or somewhere else to look at that would cause resistance
I'd rather not get it all together and immediately have to pull it back a part at the track if this is a serious prob and going to add permanent resistance to the drive train.
