Well I fudged up and did a 180 into a curb while it was raining with my racing slick tires on. Luckily only my knuckle was damaged.. The part where it connects to the upper control arm snapped. Im trying to do the repair but i have a castle nut to get off that is freely spinning since the part of the knuckle is broken... Ive tried to grab the piece of knuckle with ppliers while turning the nut but it is driving me crazy.. Cant get it off.. I just soaked it in some pb blaster and am going to regroup and brainstorm.. Any suggestions? I will post a pic

Car Analogy

Get some huge honkin vise grips, lock them onto free spinning knuckle remnant, such that nut torque will jam handle of vise grips against something immovable. Loosen nut.

Alternatively, get a big crowbar, and use it to pry knuckle remnant such that it jams conical shape of joint further into its socket, thus restraining it so nutbcan be loosend.

If all else fails..Dremmel a notch on the nut then pry it off with a large flat head screw driver.
