Harold was gracious to allow more than 2 weeks for my rental. May have had something to do with my $2400 parts purchase, including bushings.

To be honest, I don't see why everyone says the job's difficult. Just drop the subframe 4" and go to it....pneumatic wrench makes it go much faster. Don't forget to lubricate the threaded rod! I used an old, forgotten bottle of 20/50 motor oil. Lube ingoing bushings too - they go in easy that way - silicone, please.

The tool HPA has must be crazy strong; I"m curious to know how is stronger than the one I made.

To either of you: I understand how to make the tool remove the bushing, but how does it press it in? Also, how much space is there on the other side of the bushing, 4in? (between subframe and bottom of car)

At this point, it sounds like HPA might not have the tool available in March when I need it, so I am definitely going to make my own now, so any help with the specs would be greatly appreciated.

I'm trying to understand the exact function of each part of the tool. (It should be straight forward, really). From my understanding, only parts 2 and 3 are required for the rear subframe bushings, plus the corresponding washers and rod?
