Hi all I've owned my 2007 freelander a year now and done the usual pads and service and a rear wheel bearing. Not long ago my car developed a noise that sounds like a wheel bearing but is only there when on the power mostly at constant speed from about 20m . A mechanic friend had a drive and agreed with me that it's not a wheel bearing there is no play in the bearing and it's odd that it goes away off power. I can here and feel the huming/knocking from the front drivers footwell and all signs pointed to the front diff.

I spent the last 2 days and well over 500 notes fitting a recon transfer box but to my horror the noise is still there. It gets faster with road speed not engine speed and I'm stumped and broke. My next move was to replace the osf bearing and driveshaft as I noticed the bearing on the driveshaft was dry when fitting the diff but why would the noise go away when off power? Hoping someone out there has had a similar thing and can help me keep what hair I have left

Cheers Darren
 
Yeh, the transfer box/front diff doesn't get reported as a problem on here (so much so that I don't even know what its called on F2!).

The rear diffs though on pre 2011 cars are made of cheese and I'd be surprised if they haven't all been replaced by now. The props are another thing that get replaced when the support bearings go - you can't just replace the bearings.

First things first though, when was the Haldex last serviced?
 
Not sure on the haldex service I'll check the history but it was immaculately kept before my ownership. I'm going to pull the prop off tomorrow take it for a short drive and see if it still makes the same noise on power that should eliminate anything rewards
 
Could it still be back end?, some components will still rotate, admittedly not under load but still could transmit vibration...although if you feel the vibes at the footwell then it's, as you say, highly likely to be front end:rolleyes:
These faults are difficult to determine, I've a rear drone but will drive it until it gives up then I'll know exactly what the problem was.
