My LCA bolt to the rear trailing arm is appears to be rusted. It won't break lose. Any recommendations on good ways to remedy the problem?

 

Lots of PB Blaster, and if you have access to it, an impact wrench. A torch is also a good idea. That bolt is an uber bitch, good luck man!!

 

i had a rusted bolt too, im with forty..i just used a normal rench and it was a PAIN, it took me a good hour to get it out, i just keeped spraying it with oil and going back and forth till finally it came loose, dont give up tho..when i took it out i tryed and cleaned it up with oil and steel wool, and it went back in soo easy, so i hope its fine when i take it out again..or get some new ones
