SPL Rear Sub-Frame Bushings

I started to remove the rear bushings first. Be careful. The bushing are silicone filled and will make a mess.

1st pic.I used a 2" deep hole saw to cut out the center of the bushing. you can get the deep hole saw at Home Depot.

2nd pic. I used a 2.5" hole saw to remove the rubber in the inner shell.

3rd pic. I used muffler chisel on my air chisel to remove the shell.

After the shell was out. I used a flapper wheel in my die grinder to clean out and smooth out the inner bore. I made sure there was nothing that could hang the new bushing up.

When removing the front bushings. I had to use a sawzall and cut down the top of the metal part of the bushing in the center. It's too tall to let the 2" hole saw to cut through. And you can't use the 2.5" hole saw to remove the rubber inside the shell. It's too big.

The front bushings are installed from the top by the factory. Where the rear is installed from the bottom by the factory. This caught me off guard somewhat. I had to cut the flange off the top of the factory bushing so that I could drive it down. What you can do, is flip the sub-frame over and remove the shell that way.

1st pic. Smear anti-seize inside the bore. Next, install the bushing from the bottom. Here, I use my trusty ball joint press. When tightening down. Take a big hammer and tap on the sides of the sub-frame. The vibrations help the bushing to slide in. All the SPL bushings are installed from the bottom.

2nd pic. Installed.

3rd pic. All 4 installed.

Now you can slide the sub-frame back under the Z. Carefully jack the sub-frame up. Make sure your body studs align up with the holes in the bushings. It will hang up easy if you ain't careful. Once you have the sub-frame almost home.

1st pic. Slide in your spacers. 1 thick and 1 thin in the front per side.
The rear gets 1 thin spacer per side.

2nd pic. The rear bushing.

3rd pic. The front bushing.

Now you can reassemble in reverse order. Remember your torque specs.

Have fun.
