Hi all.not sure if i in the right area for this.bit looking for bit of help.i recently changed my diff on an english axel.but it had small flange.i needed big one.so i chanced my arm by marking nut.checking the torgue also.and counted turns of the nut.put it all back and all looked good.but today after driving maybe 50km.its now whirling.not wining if that makes sence.my question is do ye think i can now get away with a new crush washer and resetting the pinion.or is it diff change time again.as above its only a whirl.and really only coming back down through gears.
