Well, I was able to build the spring expander tool and get all four springs replaced on the front lift jacks.
This is without a doubt the best and easiest way to perform the replacement.
My coach has the type of system where the foot of the jack just falls off the ram when the springs are removed. So, I needed to buy parts to construct two spring expanding tools to make this job a snap. Once the springs are expanded to the correct length, I just hooked one spring end on the foot and then the other so the foot hung about 1/2" from the ram. Got into the coach, turned the system on and hit the down lever on the front rams and the ram met the foot and the tool fell right off.
Now, I did use a cut off wheel on my drill motor to cut the old spring hook off on one of the springs and went from there. With the springs in the stowed position, I did have a little bit of stored energy that flung the little hook a bit when cut. But, use safety glasses or any other precaution and you should be good.
Very nice result.
I'm ordering the rear springs asap and should be able to knock that job out in a couple hours, tops.
Thanks very much to all for the great ideas...
I will post pictures later, as my cell is almost dead and I don't have the power to upload them to photobucket.
