Is there are easier way to change the spring eye and shackle bushings on a cj7. I don't want to have to un-bolt the u-bolts and remove the spring entirely from the car. Can i jack up the car remove the front tires, support the frame with cinder blocks and support the axle with jack stands and unbolt one end of the spring at a time, replace the bushing, rebolting the end and then unbolting the other end. Using this process for all 4 springs. Tell me how to do this with the least amount of removal, and frustration.
