Hi guys, I have a Fanatec Porsche 911 Turbo S wheel. I've had it for five years, since beginning 2010, but it was barely used for most of that time. Mostly it was in storage, until Jan 2015 when I started using it heavily. In the last 6 weeks I've driven nearly every day, and would say I've done at least 100, maybe 150 hours on the Fanatec wheel. They don't make the Porsche 911 Turbo S wheel any more, because it was a special edition. But judging by the specs of the wheels they make now (Forza CSR, Porsche GT3, etc), my wheel is basically identical internally - it definitely uses the same RC "Mabuchi RS 550 Motor" internally. The problem suddenly started last night, in the middle of a lap. The best way I can describe it is that turning the wheel feels 'lumpy' or 'jerky'. When I try and turn it during a lap, it doesn't move smoothly round, but rather feels like it's moving in notches or steps. It's like it's resisting me turning the wheel, not rotating at all, then suddenly it turns a bit - a step - then again it resists me moving it, until it again it moves in one step/jerk. This only seems to happen when I'm in-game, and FFB effects are being applied. If I turn the wheel off and move it, it seems to move fine. When I then turn it on, it spins round as part of its initialisation, and this too seems fine. Then if I rotate the wheel while it's turned on - but not in a game - it again seems fine; there's more resistance to turning it than when it's switched off, but it moves smoothly. So the problem seems to happen exclusively when I'm in a car in-game. So in other words, the problem only shows when the game is putting FFB effects on the wheel to make it harder to turn. To summarise: Wheel turned off : turns smoothly, no noticeable problems Wheel turned on, not in-game : turns smoothly with more resistance, no noticeable problems In game, car not moving : turns smoothly with more resistance, no noticeable problems In game, car moving, FFB resisting the wheel : problem; wheel turns jerkily, like it's moving in steps. I'm going to try and take the wheel apart and see what I can see. But I'd be most grateful for any advice - does anyone recognise the symptoms? Does it sound like a particular component? Naturally I'm hoping it's something simple, like the belt has slipped partially off or something like that. But I have no idea, maybe the motor itself is on the way out (Which would mean it's probably cheaper to replace the whole wheel than fix it, I guess.) Many thanks in advance!
