Disconnected the steering wheel coupler by unplugging the horn ground wire, then removing two castle nuts and cotter pins on the coupler. Cleaning off some of the gunk makes it easier to see the parts. Especially when trying to get the cotter pins out.
Steering coupler doesn’t look that bad, but I’ll know more when it’s cleaned off. I always assumed I would just replace it since it’s a ‘soft’ part. There’s an interesting forum thread on the Samba.com site, that talks about using urethane couplers. I’ll think I’ll stick to a OE part like this one from CIP1.com.
