You are right,SL'S are thin walled and could break when hitting off mats.
You need a vise,rubber vise pads or a rubber shaft clamp, an easy out and a heat gun or torch.
Drill out any epoxy , apply heat, insert your easy out by tapping it in and twist the shaft out.
Come back if you have any ?'s about installing a new shaft.
