I've done a bit of googling but can't find exactly a fix..

Lately when turning left or right I hear (and feel) a rumble when turning.
It feels like its coming from the rear axel.

Just Coasting round a corner is ok,
but when accelerating round a corner I get the rumbling.
Roundabouts are ok, but any turn sharper than that and it's rumble time.

Dose anyone know what this is, or a test I can do or something to look at that will pinpoint what it is?

have you checked you inner cv joints front rear

Is there a sure way to test this?

Possibly wheel bearings

The rumbling sound is deep, imagine drumming your fingers fast on a large wooden table.
It appears to be coming from the area of the rear axel, centre.

It doesn't sound local to one side or one wheel and if it only happens when turning, I'm assuming it's happening when one wheel is turning at a different speed to the other?
And only rumbles if I'm accelerating or maintaining acceleration around the corner.
Coasting in gear or riding the clutch round a corner and there's no rumble.


I've had bearing problems on and previous car years ago, this doesn't feel the same.
But then this is my 1st all wheel drive. I could be wrong, is the test for this to jack up one wheel
And see if there's any play in it?

I'm hoping my untrained explanation is making sense to someone in the know lol

Rumbling from the front while turning would imply CV joints. The geometry of the drive shafts at the rear though wouldn't change much while turning.

I'd check your rear diff mounts.

I am thinking rear diff........ Do you have a propshaft on?

How mechanically minded are you? ........

Possibly diff front mount. Mine did the same. Lots of advice on replacement on this site.

If by propshaft you mean the long thing that runs from the front axel to the rear axel, then yes.


Mechanically minded? I'm not afraid to do things if there's a guide and it's not too tricky.

Are there any step by step guides?

Also, if it's removed what's performance like? It's only a teeny petrol manual as it is.

I don't like how they drive with no prop... But that is personal preference. The power isn't an issue as the hippo runs in 2wd mode until the power is needed to the back wheels.

Do a wheel up test as per hippos how to guide. Then unbolt the whole of the prop (the long thing from front to back) again info in hippos guide on replacing the vcu bearings.....

Once you have done that take it for a drive and report back!

Just popping back to let you guys know I've fixed it.

I followed this video, http://www.youtube.com/watch?v=NIwAXHhLe
iE

And ordered a Blanking Plate from Ebay,
Parked the front wheels up on a high kerb, hand break on and 90mins later took it for a test drive round the block.

WOW, 1st thing I noticed was it reversed out of the parking space like butter.
I mean before I would reverse and turn ready to pull away, and it was stiff, like reversing up hill Alough the ground is flat.
But now.... Smooth as silk.

Drove away NO SOUND, no rattle, nothing. The ride just feels much lighter.


One thing I discovered was the blanking plate I ordered listed as for freelander
Was half the thickness of the one in the video above.
Problem is I had to use 6 bigger nuts like thick washers so the reused nut again could clamp the plate tight.

Thing is, the bolts that hold the IRD in place have a thread then a blank bit then thread again.
The blank bit on the bolt thread is twice as thick as the blanking plate I received from Ebay
So with the nuts done up as tight as they would go, didn't hold the thing in place tight.

You follow?

Anyways, thanks for your help guys.
I'm no mechanic but with your help and the video above I took the plunge and it payed off.
Happy days.


Edit:
Sould point out that after suffering that rumble sound from the rear when turning,
She also developed a rattling sound that appeared to come from centre between the two footwells.
Looking into it I noticed the both rubber dounut things that held the propshaft in place had rotted away some time ago.
And this new sound that just rattled away all the time and worse when breaking was the IRD.

Anyhow, all sorted now like I said above.
