Spicer Rear Left Driver Side Complete Axle Shaft Assembly for 2003-2006 Jeep Wrangler TJ / LJ (Dana 44 w/ Disc Brakes)

Eliminate harsh rear wheel-end play, stop chronic gear oil leaks, and restore trail-ready dependability to your rig with this genuine Spicer Rear Left Driver Side Complete Axle Shaft Assembly. Specifically engineered for 2003–2006 Jeep Wrangler TJ and 2004–2006 Wrangler Unlimited LJ models equipped with a factory Dana 44 rear axle and disc brakes, this premium factory replacement assembly perfectly replaces a bent, twisted, or high-mileage driver-side shaft.

On trail-driven or lifted Jeeps running larger off-road tires, the semi-floating rear axle shafts endure severe leverage and torsional load stresses. Over time, high mileage can lead to micro-fissures in the steel, stripped splines, or warped mounting flanges. Furthermore, when a rear wheel bearing fails, it often scores the shaft journal surface, rendering the entire axle blank unusable. A compromised rear shaft causes deep rumbling noises, dangerous tire wobble, and allows gear oil to bypass the seal and coat your rear brake assemblies.

This master assembly comes 100% pre-assembled and pressed at the factory, arriving complete with the inner/outer steel shaft, premium wheel bearing, lock collar, outer oil seal, structural retainer plate, and all 5 wheel studs. Sourcing a fully loaded genuine Spicer shaft eliminates the need for expensive shop press equipment—letting you slide it straight into your axle tube and bolt it down immediately.

Kit Highlights:

• Direct Drop-In Assembly: Comes fully assembled with the premium wheel bearing, seal, locking collar, retainer plate, and wheel studs already pressed into position for a rapid installation.

• Genuine Spicer OEM Quality: Engineered by the original equipment supplier to match exact material hardness, spline depth, and structural metrics for guaranteed factory alignment.

• Induction Heat-Treated Steel: Forged from high-grade carbon steel and induction hardened using statistically controlled testing parameters to maximize fatigue life and structural yield strength.

• Cold-Formed Rolled Splines: Utilizes a non-machined, cold-rolled splining process on the 30-spline inner differential end, entirely eliminating the stress fractures common with generic cut-spline alternatives.

• Disc Brake Specific Geometry: Engineered with the specific flange spacing and a 2.842-inch brake pilot diameter required to clear factory rear disc brake calipers and rotors.
