The castle nut on my ball joint stripped while trying to remove the knuckle.
Where would one get just the castle nut?

I think its 14 mm 150?

Checked all the local stores, no one even has a 14 MM nut let alone a castle nut. Autoparts stores say only come with ball joint.

 

junkyard

 

Buy a "spare" ball joint?

 

 

I'm thinking junk yard. Having no luck finding one.

What the heck would I do with a spare ball joint?

 

keep it so when u need a new one you will have it

 

junk yard would be your best bet...r maybe a Nissan dealer if your willing to buy a brand new one...
