She got out, locked the front hubs, shifted into four-wheel-drive, pulled on to a dirt lane between fields, and drove for half a mile or so.

Dynohubs were offered as front hubs and as rear geared hubs.

(The 3.2-litre V6 petrol engine version was also available with an optional four-speed auto and auto locking front hubs.)

It uses many other components from the Sierra, including front hubs and steering rack.

Rather than the common system of articulated drive shafts to the front hubs (the shaft either inside an axle casing or external), fixed shafts were used.

Other modifications were 16-inch wheel rims, locking front hubs, a heavy-duty steering box and 305 mm diameter front brake discs.

The distance from the bottom bracket to the front hub was 605 mm instead of 600 mm.

On the back of the steering wheel, a cheap-looking, ill-fitting plastic cover failed to align with the front hub.

The gearing is 1:1 (the pedals connected to the front hub), so the gear is low.

Drum brakes have been used on front hubs and hubs with both internal and external freewheels.
