Tank...It only happened that moment when I got in the car after work, that was Trurs. evening. I drove another car the next day, but last night I sneeked up on it and poked my head in the drivers window....no noise, then I opened the door, and still no noise. When I rolled it out of the garage this morning, there was no noise. Maybe its one of those intermittent things that nip you in the rear when you least expect it. I don't know if it was related or not but about six months ago the battery was next to dead, I recharged it then took it down and load tested it, it tested OK and has been OK since....Who knows??
Freestyler...Theres about seven or eight keys on two rings connected together with a light weight clip. Probably slightly more than there should be. But then theres the factor of how much weight the PO packed on there for many many Moons prior.
Im just going to have to keep a close ear on it.
