Drives sortof shakey so I removed front driveshaft thinking that maybe it had been knackered or perhaps in need of new ujoints. Went to drive her in 2 wheel drive and she doesn't move -Just sounds like transfer case gears grinding. Our Disco may have failed in its transfer case and I'm not sure how to think of that. Anyone been here before? I've installed LT's into our other BW Rovers but never had to build one. Thanks.
