Gotta take the rear axles and bells apart. Plan on leaving the banjo and spring in the car.
Never did this before.
With the frame up on stands and the rear axle housing hanging down with the tires off the ground, I imagine the spring bowing together slightly when the weight of the car is off of it. Is the spreader installed at this time and used to slightly spread the spring eyes apart again to take pressure off the shackles and prevent the spring from completely unloading when the shackles are removed?
Will the shackles be a little loose with the spreader pushing the spring eyes apart slightly? Is this how you know it's safe to remove them?
I'm getting a little nervous about this job.
