Southern E3 AA (2003). I've removed the four cab screws but the chassis won't budge. Of course I don't want to force it and damage something. Do I need to remove the speaker unit as well? Or? I've been able to finagle the tires onto other units without removing removing the cab shell. But I thought this time I would lube the gears, necessitating removing the cab. Also, I can't seem to locate an owner's manual for this unit. Any ideas out there?
