Since I replaced my second set of Goodyear Wranglers for new quieter tyres a few months ago I have been able to hear a whining noise from either the engine or transmission (auto gearbox - mileage 97,000). It's noticeable at lower speeds when accelerating through the gears and makes the car sound a bit like a sewing machine. It's not particularly loud and at higher speeds road noise drowns it out.

I mentioned it on my last service at an independent 4X4 garage but they said it was probably an auxiliary belt or pulley bearings but I had the impression they hadn't really listened for it. The belts don't look worn to me.

Has anyone else had a similar problem? I have done searches on this forum but haven't found anything similar. I have tried stuffing a rag around the steering column grommet in the bulkhead but that made no difference, I can still hear it at the same level.

the last whistle i had, (on my old car) that could be heard in the same manor as yours was the turbo, if i recall correctly Former Mod/Member, with the most post & Chicken George Arch nemesis

Could it just be a characteristic hum from a different tyre tread pattern?

You can get a whine from a worn aux belt tensioner. Sounds similar to the noise the steering pump makes on its way out. Mine was quite loud though, as I recall (that was on the 07 GS, only noticed it after I'd had the steering done on extended warranty. I then found the warranty didn't cover the tensioner.) Ex AA Series III LWB Safari - Gone

Thanks but it definitely isn't tyre noise.

Hi Sid,
Thank you but the noise seems to go up and down with engine revs and I've got new road biased Michelins on which are almost silent on a good road surface. I think I may have had the whine before I got rid of my 4mm tread Wranglers but the noise they were making probably drowned it. 1982 RR Classic-converted to 200TDi-gone

My aux belt tensioner when that started to go on my last FL2 at around 50000 miles made a clicking noise rather than a whine.
Strange everything seemed to go wrong around that mileage, flywheel, clutch, wheel bearing, diff, tensioner.

No mine was definitely a whine. Certainly it's a place to start, especially if as you say it varies with engine speed. Ex AA Series III LWB Safari - Gone

Hi, just an hour ago i was reterning from a weekend to the country from the country road which is full of turns at 30- 45 mph on my 2007 td4. Suddenly on a close turn i hear a whinning noise from the engine or gearbox while throttle. On a straight i put neutral (auto gearbox) with approximately 80 km per hour and start pushing the throttle pedal until 3000rpm but nothing, so now iknow that the noise isn't either from the engine or from the gearbox. So i started pressing the throtle pedan while steering and a loud differential noise started. To conclude i can surrely say that the noise appears only while pressinh the throtlle at corners.

Any thoughts? Thank you in advance. Freelander 2 TD4 HSE 2.2 (2007) Auto

Just talk to the phone with the dealers technisian. In Athens the dealer have 24h line. He gave instructions in order to identify the noise sourse. Finally we saw that come from the steering pump and more specific becsuse the filter of the steering pump needs cleaning or replacement. He hopes that because it is early i will not need pump replacement.

I went to the car and at stationary i give throttle to 2500rpm and turn completely the steering column, the whining noise started again.

Tomorrow i will go to the shop and hopefully fix by cleaning the filter and replacing fluids. Freelander 2 TD4 HSE 2.2 (2007) Auto

gasteratos, i was warned against trying to clean the filter as they can disintigrate and last thing you want is minute bits of plastic floating around the system, new reservoir only cost me £26

My mistake. He told me that it is propably the filter,and that he will replace the fluid after cleaning the circuit. Propably ( and you are right) thetank will be replaced as well.

I will keep in mind what you wtote, just in case. Freelander 2 TD4 HSE 2.2 (2007) Auto
