Toyota 4120169805 — Front Differential Final Gear Kit
Overview
Front axle final drive Toyota 4120169805 transmits drive torque from the propeller shaft to the front differential assembly and wheels. The crown wheel and pinion set is manufactured from high-tensile alloy steel with case-hardened gear teeth to withstand extreme mechanical stress. Hypoid gear geometry features precision-ground tooth flanks to reduce friction, gear whine, and operation vibration. Technical specifications include a 200 mm ring gear pitch diameter, 10-tooth drive pinion, and 43-tooth ring gear, providing a 4.30 final drive ratio. Original equipment part number 41201-69805 matches exact factory tolerances for tooth contact pattern, pinion depth, and backlash settings.
This gear set fits front axle differentials on Toyota Land Cruiser 100, Land Cruiser 200, Prado 120, and Prado 150 models, as well as Lexus LX470 and LX570 vehicles manufactured between 1998 and 2021. Replacement is required when experiencing severe transmission whine, pinion bearing play, tooth spalling, spline damage, or surface scoring caused by lubricant starvation. Fitting a genuine replacement crown wheel and pinion kit restores quiet gear mesh, prevents tooth seizure, eliminates excess driveline play, and maintains correct power distribution across the front drivetrain during heavy vehicle operation.
