Whistling Noise

[Adam]

I noticed that same noise when sitting at just above 100. I was going to see the dealer about it to find out if it was the diff. after reading this I will just wait till the 3000km inspection.

I hadn't considered that it might be the diff and maybe the window is where the sound is entering the cabin. Hmm, might have to investigate further.

Well people it turns out it's the diff. A while ago I told the service manager and he really didn't seem to keen to help, but after taking Fordtech to the FordForum drag meet at Heathcote last Saturday I'm getting a new diff at the 15,000km service. We had just left town cleared the 80kmph zone and was at 100kmph for about 15 seconds when he said "have a listen to your diff!!!". He tells me the new one will still make that noise but hopefully not at 100kmph. As long as it's not between 100 - 120kmph I'll be happy.

I'm really not sure what to make of this.

My diff has a mild to moderate whine from about 95 to 100kph. As I rarely if ever sit on those speeds, it's not a major problem apart from rare 90kph zones!

So do I ask for a new diff (because it should really be quiet) and risk getting one that's worse - or just put up with it? My previous Nissan Maxima had a mild transmission whine at 60-65kph - much more annoying!

I don't want to start getting into the caper of multiple diff transplants and the info I've read so far seems to suggest most of them have whines or backlash or some other problem!

I guess I'll ask the service manager for his opinion as I am lucky to have a really good dealer who seems happy to replace anything on request.

There's nothing mechanically wrong with the diff, it won't break because it whines. They all do it at some point. The only reason I'm replacing mine is because the whine is spot on 100kmph. If it was at say 85 I wouldn't bother.
