"clunk" noise from rear when turning at low speeds

Hello:

I bought a 2006 X3 almost 45 days ago from an independent car dealer with 72k miles. I've had concerns with a noise coming from the rear axles when i turn the vehicle at low speeds. I took it to the dealership where i purchased it and they had no idea what the issue was. I then made an appointment with the local BMW dealership to have them look at it. They had 2 master technicians ride in the car and could not figure out where the noise came from. They advised me to return the car and get my money back. The original dealer offered to allow me to trade it in or have the vehicle taken to another import specialist. After a week with the X3, they determined the issue was with the tires. So they gave me 4 new tires which i thought solved the problem. I checked the tire pressure and found they were overinflated to 38 psi. i corrected the pressure to the recommended levels to find the clunking noise had returned. I'm taking the vehicle to the mechanic who looked at it. Any suggestions or possibilities to fix?

Hmm. Looks like you've already done the first thing to check in these instances (tires); the xDrive is temperamental about tire diameters, particularly inconsistencies from wheel to wheel. But if you've got four new ones on there (presumably all the same brand and size), not sure what else to suggest other than to verify you've got the correct (i.e., recommended) tire size; consult your Owner's Manual for that information, as the recommended sizes vary according to how your vehicle was originally equipped (some have the same size all around, some have a staggered setup).

Same problem!!

I've got a x3 2.0d 57 with 140,000.
So I brought the car private about a month ago, stupidly didn't realise the clonk noise when turning at low speeds both left and right, if I get the steering angle right in a car park, it will be a continuous, clonk clonk clonk.. only at around 280 degrees of a turn...
I've got 4 near new Dunlop star rated tyres. All set on 35psi
I've checked the cv joints and drive shafts, also looked at bushes of what I could see, the doughnut type things are all good. I can't see any problems!

I've also disconnected the transfer case and the noise goes...?

This car is seriously hurting my head..
does anyone have any suggestions.

Now the shaft that goes from the front differential to the transfer case had some very slight play in the bearing so it seems to me, like 1mm up and down movement..

Any help please!!

You are killing me: "I've also disconnected the transfer case and the noise goes...?" What does that mean?
FYI - my indie mechanic "disconnected the transfer case - and the noise went away." With that info, I took the car to the dealership where they replaced the transfer case with two weeks left on the extended warranty some previous owner had purchased. Ahh - the good old days (extended warranties no longer transfer to new owners).

I mean I disconnected the connector on the transfer case and the clocking when turning goes.. thought at first as that happens it be the transfer case, but then someone told me as it makes it into a rear wheel drive as switches off the awd system, it could could still be diff or something up front.
