Control arms nut and bolt size. What sockets?

EverybodyWildOu · 05-10-2014, 06:40 PM

I'm going to be doing the suspension on my car was wondering what socket and wrench sizes I needed to the control arms. Are they the same size for the front and rear? Please let me know the sizes. Thanks.

I know the bottom nut is 17, but I think the big bolts are bigger than 18, no?

The nut closest to the diff is larger than 19mm I believe.

They're 21mm if anybody else was wondering.
