transmission whine

[LR90 lad]

hello,

ive got a transmission whine that started the other day, sounds like something is rubbing along the edge of the tyre, can hear it well with windows shut... noise varies with speed of car, but stops under about 20mph.. i have no vibration, just the noise.. has anybody got any ideas? i did the driving on full lock test in a carpark and im pretty sure im not getting any transmission windup.. theres nothing rubbing on the wheels/tyres... and it does it under load and freewheeling.... the noise tends to start when ive been driving for about 15mins... (1999 T reg with 1.8k series, 53k miles)

cheers

Freelanders are prone to tyre noise from the rears. Have a good close look at the tread. They get small flat spots, you can feel them, but are best looked at across the tread from a close distance. If you can jack the rear end up and turn the wheel slowly, you can feel the slight bumps and hollows.

If they are OK, then try the wheel bearings in the same fashion. We get them rumbling on a lot of cars, they get worse as they heat up.
Try driving and swaying about in longish distances whilst you drive ( about every 50 metres, on a quiet road, of course ;) ) as the vehicle load shifts, the noise will get loader and quieter, if the bearings are losing their track hardening.

cheers, its definately not tyre noise, the best way to describe the sound is if you imagine one of the old dynamo's running along the side of your wheel on your pushbike (the ones that used to power your lights).. it sounds like that ! very strange really.. wheelbearings had crossed my mind, i'll try each wheel and see if i can feel any play with it off the ground.. something else as well... the noise only started after the g/f bumped the freelander into a white van ..was a slow impact, just a bust grill...i dont think that could be anything to do with it though..?

Check the alternator belt for a pulley rubbing.

There is a small plastic cover near the crankshaft pulley, that could be touching. It is behind the drivers side front wheel. Just a couple of screws hold it on.

That noise sounds remarkably similar to where mine started.

Have a look at the VCU support bearings, and if in any doubt take the prop off and run in front wheel drive.

How much were they to get sorted? its not a part ive seen in the landrover mag...

I bought mine for less than £60 for the pair of ebay.
Paddocks list them at a bit more than this, as do Simmonites.

Not too difficult to change, either.

I had a similar whine which I traced to one of the bearings supporting the VCU. I raised the car onto 4 axle stands. (I've got 4 ton ones.) Istarted the engine and put it in first gear and was able to confirm that was the problem. Even although only one was faulty I replaced both. The replacements cost £25.00 + vat each and from memory I got them from Paddock. Removal involves droping the entire prop shaft and what I did was to make 2 wooden supports (from an old pallet) on which I rested the front and back before droping the VCU. It is quite heavy but with care I managed to do it myself. A hydraulic press is required to remove and replace the bearings. The car was 7 years old and all the bolts came out easily.
