Probably wear on the hook as others commented. Actually Becks do have access panels under the tunnel, but depending on the age, they may have been sealed with fiberglass. I had a similar situation and finally took a Dremel to the fiberglas so I could remove the panel on my Beck. That made repairs and cable replacement so much easier. It's definitely worth hassle.
ACK! I just realized that this is in the Spyder forum (silly me). At once point you said you have a Speedster and I forgot where I was. If it's a Spyder then ignore me (my wife does).
