I have owned my Juke for almost a year and have put 20000 miles of mostly fun drives.
However I have this annoying resonance, rhythm, cyclic, I don't know how to describe it properly. Its been doing it since I bought it last year. The noise is not constant, its like a resonance of a fine vibration. At around 60 mph I start hearing this noise but very faint, then fade away. Around 70mph it start making that noise again, up to 75mph when it is loudest. 78mph and up the noise is gone again. It sounds like whooo..... whooo.... whooo... with fading in and out between noises, like rrrrRRRRrrrrr.....rrrrRRRRrrrr.....rrrrRRRRrrrr.... When going straight, the frequency is about 1 Hz. Turning left, frequency increases depending on how hard I turn, up to 3 Hz or so. Turning right, frequency lowers like 0.4 Hz or so. Noise can be heard loudest at the left (driver's) side sitting position. Passenger side, noise is not as loud.
The noise is totally dependent on speed and wheel turning. Acceleration, deceleration, braking, transmission in neutral, etc. have no effect.
The car is perfectly smooth below 60 mph, thats why I have let it slide for so long since I don't drive on the highways that often.
I have done these:
1. Found a slightly bent rim on rear right. Bought another rim, put all new tires. Absolutely no difference in noise characteristics.
2. Replaced all front brake rotors and pads (because it was vibrating when braking). Brakes smooth but noise remains.
3. Put used tire on the bent rim, test install it to every axle points with test drive each. No difference.
4. Complained to dealership. They replaced right side front wheel bearing first. No difference. They replaced the other side front. No difference.
5. Dealer gave up and said to wait until it gets worse. Hasn't gotten worse in almost a year. I asked to consider rear wheel bearings. They brushed it off.
6. A friend sitting on rear left said the noise coming from rear left. Aha, I thought. So I went and replaced rear left wheel bearing myself. Noise is reduced, but still there.
7. Replaced rear brake rotors and pads. Found inner pad sticking. Brakes good, but noise remains, although still in reduced level state from point number 6 above.
So there is a difference since point number 6. Examining the old and new wheel bearing that I replaced (hub assembly), there were no obvious damage to the old hub assembly. the only difference is the new one is slightly stiffer.
Do you think I should replace the right wheel bearing as well? What do you think the rationale of the noise remaining but lessened by replacing a wheel bearing?
Any input is appreciated.
Thanks.
