    on my mk1 99 saxo vtr 1.6 iv noticed the hub nut is dented into the drive shaft, im guessing this is to stop it from self loosening/tightening,my question is if i replaced the bearings does this nut effect how loose/tight the bearing will feel? if i tightened it all the way up FT Tight would it crush the bearings and cause premature wear? im prety sure its a yes but need to be sure, thanks

    the indent in the nut is indeed to stop it from working loose.When you put it back on tighten to the torque recommended in the haynes manual ( around 184lbft I think, which is pretty tight)and it will be fine.best to use a new nut of the indents look cracked or bent sharply

    ok so the thing is, can this nut be over tightend and cause damage to the bearing? iv heard on some cars you get a tapered bearing, and on others you can get completly sealed bearings which can get tightened up as much as you like and wont damage/ crush the bearing.

    right just found out what the problem is!! we replaced the driveshaft with one that has a tapered end and not the flat end! which the old 1 had, {they looked identical when we fitted them}, can i just replace the bearing to suit the taper on the new driveshaft? or will the hub have to be changed aswell? thanks..
