I purchased a used 2000 Discovery Series II with approximately 40,000 miles on it a couple of months ago from a private Seller. While test-driving the vehicle, I heard a whistle or a whine when I was accelerating on the highway. It is the loudest at about 70 M.P.H.. If I let up on the gas, the whining stops. Unfortunately, I can’t tell whether it is coming from the front or the rear.

The original owner told me that the truck had made this noise from the day he picked it up and that the Land Rover Dealer he purchased the vehicle from had told him it was nothing.

I brought the vehicle into a Land Rover Dealer to have it checked out and they told me that my front and rear differentials needed to be replaced. So they replaced both my front and rear differentials yesterday under the warranty. They have test driven it extensively and they say the problem is fixed.

My problem? The truck still whines as it had before.

My questions? Does anybody have a similar noise/problem and what is it?

Its the t-case.

Make them replace that too if you want it to go away for a bit.

They are obviously incompetitent. Where is this wonderful dealer?

Mine did that from the get go, brand new. I had the T case replaced, and no more whine (from my truck that is:))

Idle tension pulley or crunched bearing, mine was doing the same thing.

I'd bet it's the T-case. He described it to a "T" (pun intended), seriously, from the description, it sure sounds like it ... All I know, is that is exactly what I experienced, and switching the whole T case fixed it ...

Unfortunately Cartner, my warranty just ran out.

The service tech at the dealer said that some Discoverys do develop this whine but the T-Cases are so good that Land Rover did not want to change them during the update to the Series II.

Does anyone know if this whining noise is indicative of a T-Case that is going to give me problems down the road?

Probably not. It will just get worse/louder.

I suggest an oil change asap to something really good like synthetic at the least and see what happens. Scoutguy was saying somehting about moroso creeping oil helping.

Oldscout,

What is Climbing oil?

George

Climbing oil is a old racing trick. The straight cut gears on some high performance transmissions and differentials can make a hell of a howl at speed. The fix is to use an additive called Climbing oil. C.O. is a polymer additive for gear oil and it makes gear oil cling to the gears and adhere to them. I have been using it in the V-drive of my boat for years. The shop manual stated that it must be used in all applications over 400hp. It stated that it helps cushion the shock load to the gear box. I noticed it was making almost no noise after I added it to the V-drive.

When I got my Disco (96 w/62k) the T/C was very noisy from 35 to 50 MPH . I had a bottle of Climbing oil left over from the boat and it worked wonders on the Rover gear whine.

You can get the Morosso brand from Summit and my local Car Quest has the Power Punch brand on the shelf. HTH

George,

Sorry, I was under the impression from your first post that the truck was still under warranty. For what it's worth, I can tell you that I was told by several people (didn't trust dealer's word only) that this should not affect the truck's performance(?), it's just more of an annoyance ... Someone told me that if you take 10 T-cases at random, you might find anywhere from 2-5 of them that make some degree of noise like that. Said it is not just isolated to Land Rovers either. Now, I have no way of knowing if that was a valid statement or not, but the general consensus I received was that it was not all that uncommon, and should not cause extra problems. IMHO, I think Ron and Robert are giving good, informed advice on this, and a much better explaination. Good to listen to what they've had to say. Since your warranty has run out, can you find another place that is familiar with Land Rovers to do work on any future needs you may have? I have to agree with Ron, it sounds like your dealer is (at best) incompetant. If I were in your position, I wouldn't worry too much about the T-case causing you any horrific problems.

Best Regards,
Kim

Thanks for the useful info.,Oldscout.
My 95 discovery also whines... She is also under no warranty and do not want to give even single penny to the dealers who always try to get my arms and legs.
Have anybody else had experience with C.O ?
Is it safe and how much volume should I apply?
Any instructions of how to do it or information will be greatly appreciated.

Best wishes,
Jinwoo

Oh, I forgot to mention that I changed T-box fluid with Redline synthetic brend about 6 months ago.
Could C.O. be mixed with syn. oil without causing any problem in the long run?

thanks again,
Jinwoo

Jinwoo,

Did the synthetic oil quiet the whine from the T-case?

Also, I would greatly appreciate some additional information on the Climbing Oil from Oldscout or anyone else who may have some experience with it. Any additional information would be very helpful. Thanks

George

After change to synthetic(engine oil, t-box,...), I notice the little bit of fuel efficiency but no change in the whining noise...
I also want to get more input about C.O or any method to reduce the whine from T-box.

Jinwoo

OK. Anyone can please tell me more about C.O. if you have any experience with them?
I went to summit racing webpage but could not find the C.O.
Which brand and how much of it should I put it to the T-box? Can it be mixed with synthetic oil?
If not which oil should I use?

Any advice will be greatly appreciated.

Jinwoo

Well, if your T case IS whining, that should be something to be glad about. It means that its still there, functioning, not doing something worse..etc. etc..
