Jeep Grand Cherokee WJ Axle - Front, Left Hand, Inner - Yukon Gear & Axle - Chromoly 4340, 30 Spline, 16.6in - `99-`04

Jeep Grand Cherokee WJ Axle - Front, Left Hand, Inner - Yukon Gear & Axle - Chromoly 4340, 30 Spline, 16.6in - 1999-2004. This Yukon left-hand inner front axle is built for enthusiasts who need a stronger, longer-lasting replacement for the WJ Dana 30 application.

Manufactured from 4340 chromoly alloy, this 30-spline, 16.6" inner axle is cold roll formed and heat treated to improve toughness and wear resistance. Yukon’s production methods deliver higher tensile strength and improved durability compared with OE shafts, making this a sensible upgrade for vehicles running larger tires or increased power. The axle is designed to fit the front left (driver) side of the Dana 30 on 1999–2004 Grand Cherokee WJ models and uses standard U-joint series compatibility.

Features

• 4340 chromoly construction for high tensile strength
• 30 splines, 16.6" overall length (inner, left-hand)
• Cold roll formed splines and advanced heat treating
• Designed for Dana 30 front applications on WJ (1999–2004)
• Limited lifetime warranty covering manufacturing defects and axle breakage
