I needed to replace all of the rear wheel studs on my NY'er, so while I had it jacked up, axles pulled, I decided to replace the rear springs. (they had a lot of surface rust, and new bushings would be nice) (sent hangers and leaf spring rubber bushing keepers out to be powder coated) Bought a set of springs from Laura at Espo (no issues here with ESPO), so on the 4th I tried to install the springs. Got the front of the spring in the hanger, put two 1 by 4 pieces in the truck well where the rear of the spring and hanger contacts the wood. Placed my 1 1/2 ton floor jack under the spring at the axle. Started jacking, and jacking, spring flattened out some, but not enough, and then the car started coming off the stand placed under the frame ahead of the front spring hanger. (BTW the rear bumper was removed.) I was still short about 1 1/2 to 2 inches of travel to be able to line up the rear hanger holes and get a bolt started. So, I dropped back and put the old springs on with the same process. Do this again with new springs and throw all the weight I can find in the trunk? Any other ideas? The stored energy in any spring gives me pause, so I want all my fingers and face intact.
