Good point ?
Now that I own an LR3, I'm so poor I can't even pay attention!
OP, if you want to isolate noises without throwing massively expensive parts at it, I recommend buying a set of Chassis Ears. I have wireless ones and they've paid for themselves 10 times over when I discovered my rear diff was on its way to the grave, but the noises in the cabin all seemed to come from the front diff. I was about to buy a new front diff before I bought the chassis ears to confirm.
