G27 potentiometer problems - help please!

[cjl9 12]

Noticed my times were getting unnaturally slow. Checked and found the throttle not going close to 100% open. Clearly, by the jiggling and spiking I have a dirty pot.

Anybody got any suggestions. Disassembling the G27 looks to be a monumental task. 

Yes, it's out of warranty. Of course.

OK. Fixed for now. Found a good video explanation.

I like the G27. I don't like the newer wheels and they're expensive.
