I just bought a freelander for my wife to kick around in here on the island and I am hearing more noise in the rear end than I think is normal. Here is the problem, I am in Curacao (tiny island no rover dr here) soi am going to have to tackle this on my own. Are there any common failures that I should look out for? Anyone know a good trouble shooting plan other than ripping the whole thing appart? Do these just make noise at 40kph?
