i cant get the bolt under the rotar off it seems to be moving with the screw does this mean i need an impact gun...cause i got the other side off

 

what, repeat more clearly

 

Do you mean the castle nut by the lower ball joint ? If you do it slowly or maybe use vice grips, you could get it off like that.

 

Heres a trick I used when taking mine off and putting it back on, I'll also assume you got the castle nut to where you still have the hole visable....get some thin wire, run the wire through the hole in the bolt and bend it down to where it wont be in the way of the castle nut and twist it together clockwise. Grab some vice grips and clamp them on the wires. While holding the vice grips loosen the nut with an open end wrench and it shoudl come off or get loose enough to where its not biting on the bolt and causing the joint to spin. Kinda hard to explain but its the best I can do.

 

ill try that thanks
