TBB000270 - Differential Assembly – 4-Pin – ReconditionedDescription: Differential Assembly a reconditioned 4 pin differential unit for the Land Rover type axle. The differential sits at the centre of the axle, taking drive from the propshaft through the crown wheel and pinion and dividing it between the two halfshafts while allowing the road wheels to rotate at different speeds through corners. The 4 pin (four planet gear) configuration distributes torque across four pinion gears rather than two,
