Installation Notes and Tips
Verify Sales Code DMD and axle ratio before ordering. Confirm the vehicle is a 4WD Ram 1500 or Ram 1500 Classic and match the front right outer position exactly. Inspect the retaining ring, seals, and bearing surfaces during installation, and replace any worn mating components before reassembly. Proper spline alignment and clean sealing surfaces are important for a durable repair.
