I followed the diagram above when I installed my steering bearings, but found trying to get the main spring back in impossible, so had to compress them with straps.
How odd! What happened exactly? The same method has been followed by many hundreds for 40-50 years with great success. It is the
safest method for the job.
Did you measure the length of your new main springs before installing them?
I admire your ingenuity!
