there is no boot grease, and the person who owned the car before me said that they were gsr axels, and they fit right in, its not like this little wobble like a bent wheel. and none of them are bent, i just put them on. its a intense ass wobble that feels like the car is going fucking break itself. im waiting on eminnodagreat to call me bc he might have a little more info for me since they did the swap.
