david nelson Posted January 6, 2012 Share Posted January 6, 2012 When driving at any speed below 50 mph the car has no abnormal sounds but at 50 mph there is a whining. I think its from the front. I can push the clutch down and its still there i can take it out of gear and turn the engine off and it still there I have change my cycle wings and its still there. I have change wheels and still there Any ideas what it is? thanks David Link to comment Share on other sites More sharing options...
Jason Plato Posted January 6, 2012 Share Posted January 6, 2012 does the pitch change with revs ? Link to comment Share on other sites More sharing options...
Bricol Posted January 6, 2012 Share Posted January 6, 2012 If it was a tin top, I'd say it was a wheel bearing. Problem with sevens is actually hearing it over the wind and road noise. Bri Link to comment Share on other sites More sharing options...
zetec Posted January 6, 2012 Share Posted January 6, 2012 I drive mine without the wife, stops any noises at any speeds! Link to comment Share on other sites More sharing options...
lavena Posted January 6, 2012 Share Posted January 6, 2012 So: I can push the clutch down and its still there I can take it out of gear and turn the engine off and it still there This means it is between the propshaft and the rear wheels or at the front wheels - because that is all that is moving. I have change my cycle wings and its still there. I have change wheels and still there This means it is not the wheels rubbing (did you change all four or just the front?). Just because it sounds like it's from the front doesn't mean it is! Although with the engine off, even at 50mph I would have thought you could tell. Brakes are unlikely - rubbing would be easier to hear at a low speed. Bearings (front or back) or the differential would be my vote. If you ask a passenger to turn their head look sideways and listen they may be better at telling where it is coming from - I presume you were looking where you were going at 50mph.

tbird Posted January 6, 2012 Share Posted January 6, 2012 😬 I was going to suggest the organic rev limiter, but yours is much funnier Tim Link to comment Share on other sites More sharing options...
Doug Posted January 6, 2012 Share Posted January 6, 2012 I get a slight whine when the car is fully warmed up from the fan belt on my Zetec. It's nothing alarming and sounds vaguely like supercharger whine. I've checked the timing belt and the fan belt when it's doing it and neither are unduly hot. It did prompt me to make sure that the fanbelt wasn't overly tight. Edited to say: - Ooops, didn't see this, sorry... I can push the clutch down and its still there I can take it out of gear and turn the engine off and it still there Edited by - Doug on 6 Jan 2012 12:44:30 Link to comment Share on other sites More sharing options...

david nelson Posted January 8, 2012 Author Share Posted January 8, 2012 been working this weekend so unable to get nack sooner. I did change all 4 rims. no change when reving the engine. only happens at 50 mph and above it does not matter what type of road surface. I guess i need to have a look at the front bearings and go from there. David Link to comment Share on other sites More sharing options...

Fil M Posted January 9, 2012 Share Posted January 9, 2012 any loose cables or tape that may begin to whine when vibrated by air. Does its pitch change as you go faster over the 50mph? ie ...fster you go the higher its pitch. Fil Link to comment Share on other sites More sharing options...
jonboylaw Posted January 10, 2012 Share Posted January 10, 2012 Does it only do it when the engine is warm and the fan running? I am with Tweeky, could be the fan housing being blown onto the fan with the force of the air. Link to comment Share on other sites More sharing options...
david nelson Posted January 10, 2012 Author Share Posted January 10, 2012 I will have a look over the weekend and see what I can see. I have some tape on the front of the wishbones so will remove that, and look at the fan ect. thanks David Link to comment Share on other sites More sharing options...

Andy Err that's not completely accurate, unless I'm mistaken there will still be a significant amount of movement within the gearbox when the car is moving even if the engine is off and the car is out of gear. The output shaft of the box will be turning and there are a number of bearings involved, but TBH you should be able to hear a gearbox problem fairly easily in a Seven.

Area Representative skeetsy Posted January 16, 2012 Area Representative Share Posted January 16, 2012 Hi Charlie, I don't think that's correct. If you switch off the engine and depress the clutch (I'm assuming the car is still in gear) while the car is moving at speed then the whole of the gearbox will be turning (it will effectively be driven by the propshaft). If you knock it out of gear, then it will just be the output shaft in the gearbox which is turning, but as mentioned previously there are still a lot of bearings involved.
