I've noticed, at high speed, a whine sound. Now, I'm not certain if this is a wheel bearing or not (my first thought was yes) but the odd thing is, when I lift off the gas the noise goes away instantaneously and returns the second I press the gas again. This makes me think it's just transmission whine. Any ideas? Is this just typical rover noise? TIA | ||

Almost 100% positive that it is a pinion bearing. | ||

Anything that needs attention or merely normal? | ||

You should replace the fluids in your diffs, t-case, and transmission and grease all u-joints if you haven't recently. If that doesn't help, remove one driveshaft and drive and see if the noise is gone - if so, you have a u-joint going out on that DS. If not, put the DS back on and remove the other and drive, same deal. If it's not u-joints, then I'd start looking at pinion bearings, carrier bearings, wheel bearings, center diff. You have to do some maintenance & process of elimination stuff though first to try and isolate the sound rather than just guessing, which can be very expensive. joe | ||

I guess whether it's a pinion bearing would depend on the definition of a whine. Bearings usually hum or squeal. But if it's coming form the front rather than center of the vehicle and is doing it under load, the pinion bearing is a real possibility. | ||

Brent, I've got the same whine on my '03 Discovery S. It happens around 70 mph. I've only got 8,500 miles on it. I took it in for the 7,500 mile service, and they changed all the fluids. The whine is still there. I had heard it's an inherent problem with LR transfer cases. JRS | ||

With your hands, shake the tires side ways, if you notice a bit of play, new bearings my be necessary. That's how I detected my need for bearings. Good luck! |
