Rumble Noise. Diff/bearing/tires

[Masterfuji]

Hi Guys,

Not sure if anyone has experienced this but hopefully someone might have. I have a 2007 D4D with 150,000km on it. Car is in good condition but I now have a noise issue. THis happens in general when you begin turning left. It can be a slight turn but the noise sounds like you are driving over cats eyes or something to that effect (not as harsh). I feel like it is front left but not sure.

Anyway my mechanic reckoned it was a bearing and when we went to do it he double checked and could not find any play in the bearings in line with the noise. When we jacked it up one wheel at a time there seems to be a bit of a shudder when you are driving it on (not the feeling you get from the ABS). He reckons this is an issue with the diff. The funny think was alot of this has started following a new set of tires and tracking but the clunk rules this out.

Anyone else ever experienced this? My mechanic is ace but this problem is doing my head in.

Thanks Guys.

Try swapping your tyres front to rear and see what happens.

I did this and it didn't solve that problem. However I was a little heavy handed tightening the nuts and snapped one wheel stud. Reckon I have a few more that I put close too. Can't believe it.

If you managed to snap a wheel stud simply by tightening them then I would be tempted to replace the lot. Unless you are built like Hercules of course and you can snap them with your bare hands...
