You mean to replace the control arm bushings?
This may work but you probably will have to chain the spring, it is very long. I don't know about other methods firsthand but I used the Klann compressor with success. It will set you back about $100 for the rental but you are dealing with something potentially very dangerous. It wasn't a lot of money in my mind considering this.
BTW, I got the steering box out. I did it the hard way by removing the steering wheel and loosening the steering column so it could slide up and clear the coupler. This should make it easier to center the steering as I should be able to put the coupler on the box first. What is up with the cost of a new coupler??? $125
Resealing the box looks like it will be difficult.
