Question Replacing bushings with dry ice

Have anybody replaced bushings with the help of dry ice (solid CO2)? I'm asking because I'm going to replace 6 bushings and 2 ball joints for lower control arms and, since the procedure is very difficult - I'm looking for any hints how to simplify the replacement.

Definitely, the dry ice must decrease the external diameter of the bushing but I don't know how much precisely.

I replaced my upper ball joints by doing something similar. I placed them in the freezer overnight. In the morning I took everything apart and pressed the old ones out(the hardest part by far). After getting the old ones out, I ran inside and got the frozen ball joint and it pressed in pretty easy. Then did the same thing for the other side.

Good to hear that. If freezer helped (-20C, I guess), the dry ice should be much better (-78C).

How did you press out the old ones? I'm going to use this toolset:


Do you know whether the set is suitable for this kind of work? I am aware that it suits well for ball joints but unsure I can utilize it for bushings.
