The modification programme: £940,000 of mandated changes before design acceptance in May 1990, withdrawal from June to November 1992, full withdrawal in December 1993 after 37 of 57 vehicles pulled left braking at 35 mph, and re-acceptance in August 1995.

The record
The cause was the combination of permanent four-wheel drive, the rotating mass of the Perkins Phaser and front half-shafts of unequal length, which produced torque steer under heavy braking. The dual-circuit vacuum-servo drum brakes were upgraded and the hydraulic actuation made consistent. Reynolds Boughton paid £250,000 of the rectification; the Ministry of Defence about £1.5 million, and £1.7 million more to store the fleet meanwhile.
