The stock bushings are a soft compound rubber and flow as a result of weight resting on them. I found my bushings had not worn that much in 240k miles, but had flowed quite a bit.

Here is a shot of the bushing from the rear of the control arm:



You can see the difference in thickness on the two sides. The thin side is where the weight rested.

Here is a shot of the front bushing:



The front did not flow, because it does not carry a constant weight load like the rear.

Because of the flow property of the bushings, old bushings need replacement regardless of mileage.

Here is a picture of the bushing profile.



The bushing is not worn. There is a groove where the arrow points, but I believe that is molded into the bushing since it was uniform around the circumference.

I found a good way to remove the bushings. In the word of Butt Head - Fire, Fire, Fire.



Heat the outer metal. It has less thermal mass than the control arm and will heat faste. Didn't take much heat, just enough to see a wisp of rubber smoke.

Then just use a screw driver to twist off the outer metal.



The bushing is not glued, so with the metal off the bushing can be slide of easily.

hammer Comments: thank you Nick

  Followup from the Pelican Staff: No problem. - Nick at Pelican Parts  
hammer Comments: do you recommend poly bushing? do they squeak bad ?
December 21, 2015
  Followup from the Pelican Staff: I don't like Poly, unless it is for a track car. That's my personal take on it. Ride gets a bit harsh and there can be noise. I have friends who love them for the street. So if you are looking for a stiffer ride, give them a try. - Nick at Pelican Parts  
hammer Comments: what angles do you index the mounts with the new bushing
December 20, 2015
  Followup from the Pelican Staff: You want them to be in the loaded position. Note the angle of the old ones, before removing. - Nick at Pelican Parts

  Followup from the Pelican Staff: Thanks, remove the bolts for the front and rear bushing mounts, then the fastener for the connection to the spindle. - Nick at Pelican Parts  
Zee Comments: How do you get the A-Arm off???? All these articles START at the bench with the arm off. I cant find a single article/video anywhere that SHOWS what you unbolt to drop the front A-Arm so I can even get to the point of replacing the bushings. I have the strut off. I dont want something to spring/pop back and kill me. Even the Hayes book is useless. It says I need to remove the arm, well DUHH!!!

  Followup from the Pelican Staff: What year and model are you working on? - Nick at Pelican Parts  
worn Comments: Well the title says replacement. What we got was disassembly by fire with poor safety precaution. If you told us how to put the bleeding thing back togetether again... Well you might sell more bushing kits. I agree with kak!

  Followup from the Pelican Staff: Thanks for the feedback. This looks like a contribution from a community member. So it may not include the same level of coverage you are use to with our other tech articles. - Nick at Pelican Parts  
Eric Comments: Hey.. how long did it take you to do it?.. was it difficult to take out the torsion bar? and lastly.. do you have to align the front or rear mounting points? I noticed that they are twisted at an angle.. Thanks Eric

  Followup from the Pelican Staff: If you are working in your personal garage with minimal tools,plan for a day to replace both sides. I would mark the bushings before removing, this way to get them in the right location when reinstalling. - Nick at Pelican Parts  
LH Comments: To move on...great you-tube video on this subject
