G35 - SPL Solid Rear Subframe Bushing Install

My entire suspension has been replaced with adjustable arms, and all of the bushings have been changed to either solid aluminum or spherical bearings. This makes the car very rigid, but all comfort is completely gone. It is very good for the race track, but definitely not so good for a daily driven street car. The only factory rubber bushings that were unchanged on my suspension were the 4 large rear subframe bushings.

This job is a little bit of a hassle to do. I've had the parts in my garage for almost 1 year and have not wanted to do the work, but this weekend I finally decided to start it. The problem is you must completely remove the rear subframe, all of the suspension, rear pumpkin, axles, brakes, etc, so that you can press out the factory bushings and press in the new solid aluminum bushings. Not difficult work, but very time consuming.

I first removed the entire rear subframe with all parts still installed. I then removed all of the parts from the subframe and pressed out the factory bushings.




Here is a the new solid bushing compared to the original rubber bushing.


Once all the old bushings were out, I carefully pressed in the new solid bushings. This is a little awkward since the subframe is so large and oddly shaped.

All bushings pressed in!

Tomorrow I will reinstall all the parts back onto the car!
