Re: [ST] Recall on ST '01 and '02 rear wheel bearings

Excellent explanation Matt.  I still don't know why they didn't use a cotter pin type of solution or some other key method.  Throwing away and then finding such an odd nut is p-ss poor engineering in my book.  Also, that isn't the only nut I have had fun and games with.  My front axle was a sweetheart too.

Once the nut is tightened, you take a screwdriver and hammer and bend the metal flange into the channel.  This "stakes" the nut and prevents it from turning/coming loose.  This is important on something like the drive shaft where the forces and motion of the wheel and engine could work the nut loose, which could be catastrophic.
 
If you look at the nut on left side the swing arm (the big nut in the center of the black plastic - same size as the nut that holds the wheel on from the right side), you will see the metal flange bent in at one point.

For the mechanically naÃve amongst us: what is a 'staked' nut?
