The front axle of a Dodge truck or SUV axle can be replaced by completely rebuilding the axle and differential or by replacing the entire unit with a used or custom-built front axle. The first step to replacing any component or the entire housing of a Dodge front axle is to identify the axle in the vehicle. Typically, differential repair shops, transmission shops and some general repair facilities are able to replace parts or swap the housing.
Differential identification tools such as the one provided by DiffWizard.com allow users to input year, make, model and drive type for a Dodge truck and have the available front axle options presented. Visual identifiers such as shape of the differential cover, number of cover bolts, straight- or independent suspension axles, or CV-style axles can then be used to identify the axle in a particular vehicle.
Differential repair specialists, such as Randy's Ring and Pinion in Everett, Washington, specialize in axle repair and replacement. In addition to differential identification, DiffWizard.com gives users regional lists of distributors and repair facilities for differential and axle components manufactured by Yukon Gear and Axle. Repair shops such as these specialize in the type of work necessary to replace or repair a Dodge front axle.
