I dont think it was the weight.

MY 110 weighs 2.3 ton and that has a hiab and a big winch bumper on.

So im guessing the 90 can only weigh 1.5-1.75 ton.

The issue is landrovers do not have a "normal" handbrake yhere a cable goes to the rear brakes, as these would get ripped off when off road.

As the landys are permant 4x4, the handbrake is actually built into a drum at the center of the chassis where the front and rear propshafts join the transfer box.

So although all 4 wheels are braked with the hand brake, rather than be locked solid, the "play" in the propshaft uj's and differentials. means the with the handbrake on the wheels can rotate back and forth about 1/5 of a turn.

hence why when the landy was lifted the wheels turned and it tipped.

If you watch a landrover park up, you will see normally when the driver gets out and removes their foot from the brake you will see the car roll fowards a few inches. ive scared a few people before, as they think you havnt put the hand brake on when u jump out.
