Clamp the spring in a vice.
Remove the tie clamps.

Slowly open the vice to gradually remove the load from the spring.
Assembling the spring
Assemble the spring in the reverse order of disassembly, having previously lubricated the sheets that do not have anti-creaking gaskets with graphite grease.
In this case, the holes of the sheets are centered using a metal rod, and then, after compressing the entire package, the rod is replaced with a center bolt. The bolt head should be at the bottom.

When installing, take into account that the short end of the spring should be directed forward in the direction of travel of the vehicle.
In this case, the stepladder nuts must be tightened until the flanges of the cushion cages touch (arrow in the photo).
Finally tighten the remaining threaded connections of the rear suspension with the car standing on the ground.
The two nuts of the earring pins must be tightened evenly to avoid distortion.
