asking cos i thot i had the circlip correct, fix up the truck, then went ahead to break-in the diff by setting one side down while slowly applying throttle. but less than 2 mins in i felt something like a click and then the diff failed!
more than a dozen screws later flipped the circlip and went back to breakin it in..

in all honesty i could barely tell which side is 'flatter'? and i tried my best to face the 'flatter' side away from the thrust washer.
just wanna made sure it can be done like above in case i do a rebuild?

thanx
