I just did this job a few weeks ago. You need to heat the nut on the cam bolt then spray it with a penetrating oil. This sucks the oil into the threads. If the bolt is spinning inside the bushing you'll have to cut the bolt. Control arm bushings and cam bolts dont get replaced very often so they will probably be frozen.if you cut the bolt on either side of the bushing inside the frame you can easily remove the control arm. I used a torch to cut them, just be careful of the control arm itself and the frame. Do this in a well ventilated area because once you start,you will probably burn all the rubber out. Also have someone ready with a fire extinguisher just incase. I had both an extinguisher and compressed air to extinguish the flames. The rubber will burn out and you'll be able to remove the metal sleeve with the frozen bolt inside it. Then all you have to do is press out the outer metal sleeve(old bushing). Best way i found was to heat up the control arm(i used a propane torch with a small tip) just where the outer sleeve contacts the control arm. You can also used some pb which makes things go alittle easier if they're really rusted. Then just used a metal punch and work all the way around the sleeve until it comes out. Run a light grinder on a dremel or sanding disk inside the control arm where the bushings press in to remove and burrs. Then use a press if you have access to one or heat up the control arm(like you did to remove the outer metal sleeve) and hammer the new control arm bushings in. The service manual says to do it with two sockets and a vice. Unless you have a really big vice, this way doesn't really work too well.

 

Also, when you go to reinstall the cam bolts, cover the entire bolt and threads with antiseize. This will prevent it from seizing inside the bushing. And then obviously get the alignment as close as possible, and take it to an alignment shop.

 

Tap nut with brass hammer to crack the rust. Soak in Kroil (a real penetrant, unlike WD-40 or PB Blaster). See if this gets you anywhere.

 

Nothing works as well as Kroil.
