One last question. I believe I am in a heap of trouble right now. I marked the locknut with a screwdriver and hammer. Just a quick whack on it to leave a mark. I put another one on the housing so I can line everything back up to specs. Since I used the impact to get the nut off, it completely tore away my mark. Now I have no sense as to how tight to put the lock nut. After talking to Nissan they said it can be anywhere from 220-500ft lbs. If I tighten it too much, I could freeze up the bearings. If it's too loose I could tear up the bearing and have another mess. Is there any way to figure this out without chaning the crush sleeve?
