Replace Bushings
[axle nut] [muffler] [differential] [trailing arms] [subframe] [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. |
