If you ever get to the point where the glue fails and need to drill, this is how I remember Tom doing it in his shop on mine:
- Disconnect the sway bar links & shocks so the axle can hang free (remove rear tires also)
- Jack up the rear of the Jeep and put it on jack stands on the ‘frame’ rails
- Jack up one side of the rear axle. The other side should hang down far enough that the spring can be removed (a slight bit of persuasion from a pry bar might be needed on the spring but not much).
- With the spring removed, drill a hole in the lower spring perch. Drill a hole in your hockey pucks to match.
- Reinstall the spring. Before putting weight back on it, feed the hockey pucks into place. Use a grade 8 bolt and locking nut to bolt them down while inside the spring.
- Repeat the process on the other side.
