DESCRIPTION & OPERATION
Note. This article also applies to Lexus LX470. Refer to Land Cruiser, unless otherwise indicated.
Note. For Electronic Locking Differential (ELD) electronic controls testing, see ELECTRONIC LOCKING DIFFERENTIALS article.
Drive axle assembly is a hypoid gear-type with separate carrier housing. Drive pinion transfers power to the ring gear which provides power to the side gears and axle shafts.
Some rear differentials may be equipped with Electronic Locking Differential (ELD) system or Limited Slip Differential (LSD). For ELD diagnostics, see ELECTRONIC LOCKING DIFFERENTIALS article.
AXLE RATIO & IDENTIFICATION
Axle ratio may be determined by dividing number of ring gear teeth by number of teeth on drive pinion. Vehicles delivered from manufacturer with large tires have a higher numerical axle ratio. Equipping vehicles with larger diameter tires may alter axle ratio from factory specification.
