[QUOTE="Lee36328, post: 229469, member: 113"] Rattling undercarriage noise - solved! [B]Occam's Razor - Mystery noises [/B] You know how sometimes the most complex problems actually have a simple solution? Occam's razor - the simplest explanation is usually the correct one. I have been living with this perplexing noise problem for a couple of months now. A rattling noise would emanate from the undercarriage when I take a left hand corner. The exact location of the noise was hard to pin down. The initial suspect was CV joint. This required a change of the output shaft. RM1k plus. The other suspect was the long shaft (aka drive shaft, depending on whom you talked to.) RM2k plus. But no guarantee it would fix the noise, so I decided to live with it for a while since it did not seem to affect anything other than my peace of mind. The noise of course did not go away but got progressively worse. Finally, my mechanic and I noticed the exhaust rubber mountings were worn. Replaced the mountings, and the noise was magically gone, removing years from the car's age. So, instead of CV joint 1k plus, or long shaft 2k plus, it turned out to be some rubber, RM255 incl labour. So, moral of the story. Go for the simpler fixes first. [/QUOTE]
