The cross shaft is a core component of the differential assembly, acting as the pivot pin that locates the differential spider gears and allows torque to be distributed between the two driven axle shafts. On 2-pin differential units, this shaft is subject to wear at the contact faces where the spider gears rotate, and a worn or damaged cross shaft will cause increased backlash, uneven power distribution, and audible clunking under load. Correct replacement restores proper differential function and prevents accelerated wear on the spider and side gears. Key Features Designed for 2-pin differential units as fitted to specified axle code ranges Direct replacement requiring no modification during installation Matches OEM specification for applicable Dana/Rover axle assemblies across the listed fitment range When replacing the cross shaft, inspect spider gears, side gears, and thrust washers for wear and replace as required Vehicle Fitment Fits Defender (1986–2006, axle codes 20L–23L, 42S–LA930456, and 4-cylinder with brake drum to KA930455), Discovery 1 (1989–1998, 10 and 24 spline), Range Rover P38 (1995–2002, V8 2-pin diff, axle codes 50S–WA410481), and Range Rover Classic (10 and 24 spline).
