I own a Range Rover Classic 3.9 automatic '92 with Borg Warner centre diff. Last week I replaced the rear wheels by bigger wheels. The difference in diameter between front and rear wheels was about 2 inches 
.
A hugh mistake :doh:.
After driving for about 1 mile the car slowed down and came to a full stop while the steering wheel forced to the right. I waited a few seconds, slowly accelerated again ander after 500 meters the same occurred. Very, very scary. I turned the car to go back home, and after about 500 meters there was a snapping sound (a loud and short tick) coming from the back of the car. Immediately the problem seemed gone: no more slowing down, no more stopping, no more pulling to the right. Everything seemed normal again. Carefully I speeded up: at speed around 50 mph I hear soft ratling sounds coming from the back, while the car is lightly vibrating. I refitted the original tyres, the sounds and vibrations at 50 mph are still there.
Checking the internet, I now realize I haven't been particularly smart. Trying to locate the problem, I first checked the visco-coupling: I jacked up the left front wheel, with force I can turn it round, 6, 7 times and more, it does NOT lock up. I read a lot about locked-up visco's, but mine isn't locked. So temporarily removing the front prop shaft (to force 4WD into 2WD) is of no use.
Who has a good idea of what's damaged in my car?
