740 front bushings - to replace all, or some?

I bought a set of bushings for my front end and so far so good. I
pulled the radius arms off and will bring them to the shop tomorrow to
press out the old bushings and in with the new. I also will swap out
the radius rod bushings closest to the hub. These are a piece of cake.

The tough nut (literally) I am dealing with is the control arm bushing.
The end under the shock was easy, but the opposite end with the bushing
is a BEAR. I already broke one socket using my foot trying to force it
off. I can't get an impact wrench in there and my next attempt will be
a heavy duty spanner wrench.

Just to be sure, with 200,000 miles, is it safe to think this bushing
is worn, or should I just not bother now?

Thanks,
Jamie

 

I bought a propane torch today. What's the best way to get the nut off
using heat?

Thanks!

 

Do the anti-sway bar bushings affect steering? They are cracked, but
don't seem split. I am trying to tighten the front end and didn't know
if you can feel play or vibrations of these are loose.

 

OK, the car is back together. My efforts to remove the rear control arm
were useless. I don't hear or detect any problems so those are going to
stay. Otherwise it seems much better.
