Replace Bushings

There were many different ways documented on Dale's site and others, on how to remove the bushings. I pretty much used Mark Fiumara's plan with a few differences because of the tools I already had and the parts that were available. First I lit a propane torch and heated up the metal around the bushing. I heated it until my garage smelled like somebody lighting up their tires at the start of a drag race. Then I took two large flatblade screwdriver and wedged them in-between the bushing and the subframe. Pry down as far as you can to get the bushing started. Then I took a 6'' puller and put one side on the subframe at the section where the bushing is indented a bit (this way the puller doesn't catch on the bushing), and the other side on the joint between the top and bottom of the subframe. I was a little concerned about damaging the metal, but the amount of force it took to press the bushing out was faily low so no damage was done.

More bad focus

   
To put the new bushing back in I took 2 2.5'' PVC pipe caps and drilled a 1/2'' hole in the center of them. If you can find a 2.5'' and a 2'' steel pipe cap like Mark recommends it would work much better, but I couldn't find any. Anyway, then I jam-locked two nuts at the end of a 1/2'' threaded rod, put a washer over the nuts and put one of the pipe caps face up over the nuts (That's the larger cap on the top, in the picture). Then I took the rod and ran it down the center of the subframe and through the center of the bushing. I put the other pipe cap on the bottom of the bushing with the rod through the center of it. I put another washer on the bottom of it followed by a nut. Then I just simply held the nuts at one end of the rod with a wrench and tightened the lower nut. This will squeeze the bushing into place. Oh, one other thing, before tightening, I liberally sprayed the bushing and subframe with lithium grease.

Now as you can see by the picture the bushing is longer than the subframe so I hit a point where the bushing hit the pipe cap (this picture was taken after the bushing was already completely seated). If the upper cap were a 2'' pipe cap (what Mark recommends) it would be especially handy, because you could reverse it so it was pointing down and the bushing would fit inside it.

   
Since I could only press the bushing in part way using the procedure above, I had to finish it off with a puller. "Why didn't I use a puller to start with?" you ask. Well, because the puller wasn't long enough to fit the bushing and subframe.

This picture is upside down with respect to the previous one

   
I also replaced the trailing arm bushings. They were a little easier to do. I heated the trailing arm again just like the subframe. Then I simply used a 3'' puller with a washer to press the old ones out. I also had to cut part of the bushing that sticks out so the puller could grab onto the trailing arm. Otherwise it would just grab onto the bushing itself.

Geez, somebody needs to teach this guy how to focus

   
Pressing the bushing it was easy as well. I sprayed liberally with lithium grease again and used a 6'' puller to press the new one in. The hooks on the 6'' puller were a little large and the bushing ran into them, so I just finished off with a 3'' puller when the bushing got that far in.
