Well I love my '06 LR3. But at 74k it sounds like the rear diff., is going out. This is a common problem with the LR3. The sound is like metal to metal grinding. And no it is not the brakes, that I have checked. Rebuilt diff., is 900, labor I do not know yet. I went from a '95 RRC LWB to this LR3, and it is night and day. I hear that people really enjoy the improvements the LR4 offers over the LR3 too. It seems almost impossible that I get into the low 20's on the highway also! I barely managed 15 in the RRC.
