Today I brought a 2001 v6 2.5. Auto freelander. I gave it a test drive and all seemed ok. In a city couldnt really test it properly barely made it above 30 flat roads and no chance to accelerate fast. All seemed good so I parted with my hard earned and drove it home. Now I am worried as there is a noise that seems wrong its pretty hard to describe like metal on metal worn brake pad noise but it only happens when accelerating hard or up hill basicly under stress. Revving the engine standing doesn't make the noise in fact it sounds sweet as a nut. So first I thought it sounded like an exhust problem but surely that would happen standing. So maybe a transmission problem. But I don't know what it should sound like. The brake pads are worn and do squeal a bit with a little metal on metal so I know they need attention. This is probably wishful thinking but is there some reason the brake pads would grind going up hill or accelerating? I guess a change will reveal this but as you can imagine I am feeling a little stressed at the idea of buying a pile so am checking to see if its a known noise.
