Noisy rear diff
Posted 27 August 2011 - 05:44 PM
Had my 2 ltr Diesel (L series) Freelander (year 2000) serviced recently. It's a good pal of mine who does it for me, and I know he's OK. He told me that the rear diff was noisy. To be honest, I could hear 'something', and I thought it was a wheel bearing. He told me the wheel bearings were checked and are fine.
Where do I go from here ? My mechanic mate says that it's not something he does, and I'd need a specialist. Do I need the rear diff replaced totally ? Or do they remove and repair the old one ? I thought it was just a series of bearings ? Can they not just replace those ? To be honest, I don't know much about diffs etc.
Is it a big job ? Any idea how much I'm looking at paying ? I'm keeping the motor, so am not looking to bodge and sell.
Any help or info' on this would be very gratefully received.
Thanks for any help .................. Matt.

It's actually quite easy to remove the differential, so not an expensive job if you pay someone to do it.

First though, I would confirm it actually IS the diff that's noisy, if your mechanic mate isn't "specialist" enough to do the really-quite-easy job of swapping a diff then I'd want a 2nd opinion. VCU support bearings can go rumbly, or prop UJ's, both of which are less expense than a diff.

I'm not confident enough to attempt the job by myself. I use the vehicle everyday for work too, so if I knacker it up, I've got no transport. There is a specialist over in Birmingham called Central Axle Services. I phoned him and he said that 'I'd' be able to get one from Land Rover directly, at a cost of £295.00 ? ? ? To be honest, I wasn't convinced, sounded like he didn't want the job. Unless that was plus V.A.T ? Even so, sounds too cheap.
He also said, that it might not be the Diff, and may be tyre / road noise. He did say to take the Freelander over to him, and he'd have a listen. To be honest, the noise isn't apparent until about 35mph, then goes away again about 50mph. Not sure what that indicates.
The story continues ...... will keep you posted !
Cheers for the help. .................. Matt.

Since I can only hear this noise when the back of the car is empty (and the seats are out) I think the only sensible option is to do nothing, and wait for it to get worse. Otherwise I could spend thousands chasing it. OK, there is a risk that whatever it is will give way when I'm 200 miles from home, but that's what the AA is for, surely?

I think I'm going to have to take it down to him and get him to have a listen whilst I drive. We're off to Wales in October, so want it fully fit for then !
Cheers. ......... Matt.

Been to a Land Rover specialist today, to see if I can get some answers about this problem. They guy I spoke to seemed really nice, and obviously very knowledgeable.
I explained that my Freelander was "humming" from the rear. He told me.....
"It could be as simple as a wheel bearing. However, it could be the rear diff, as they are known for that. Alternatively, it could be the 'I.R.D' (I think it stands for Intermediate Reduction Drive - or something like that). If the I.R.D is at fault, this in turn will make the rear diff fail. If you replace the diff and not the I.R.D, the diff will last probably 12 months, before it needs doing again. If the I.R.D does need replacement, then the bill could be up to £1200.00.
However, we'd really need to see and listen to / drive the vehicle before we made a diagnosis."
I'm going to book the car in with them for them to have a look at. If the car does need £1200.00 worth of work, is it really worth spending it on an 11 year old Freelander, which is probably worth £1700.00 as it stands ?
Oh dear .... not sure what to do now !

Have you tried any of the suggestions above? If you can operate a spanner you can unbolt & remove the propshaft & VCU and that will immediately show you if they were at fault or not.

So, I have replaced all the oils and I am getting the tyres, balance and tracking done tomorrow. Next week I am going to do all of the brakes, and I'll have a look at the bearings whilst I am in there. IF the noise (comes at ~50MPH) doesn't go away with all of that, what should I do next? Remove the VCU to discount that? Replace the diff mounts that look (to my very untrained eye) like they need doing?
Also, there is a lot of play in the front wheels when I try to turn them by hand. The play seems to be at the joint to the gearbox....is that normal?

Finally got round to taking my Freelander into a specialist today. Just to 're-cap'....... Rear Diff started to 'hum' and whine quite loudly a few weeks ago, and had loads of differing views on what it could be. So, this morning, I eventually got round to taking the vehicle in to be looked at.
So, the verdict is ..... To start with, as I thought ....it needs a new rear Diff. They could find me a good very servicable low mileage 2nd hand one, which will cost me £200.
Also, the VCU (Viscous Coupling Unit) was in pretty bad shape and desperately needed replacing. This apparently, was the cause of the damage to the Diff. So, new VCU .... £400.
Also, the mountings for the VCU need replacing at £70 each. (x2)
Then there's the labour......
Total bill for the job to be done will be £900 + V.A.T.
OUCH ! ! ! I guess it's cheaper than buying a newer Freelander.
I've told them to go ahead, and I've got to collect the motor middle of next week.

Surely when a Diff is gone surely it does not go overnight and the problem started long before the guarantee was up but still they said no
I will NOT be buying another Land Rover
