Nut & Bolt Size
 

Does nnyone know the nut and bolt size on the knuckle of the 2001 chevy monte carlo ss pace car? I am going to repalce my front end struts but need to make sure i have the right socket size before i take it all apart. Any ideas? I cant find it online anywhere and have called a few part places that have no clue either....:confused:

21MM is what mine were. You only need a socket on one end because the other are like wheel studs and do not turn...
