Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It fits the inner wheel end position of the hub and is replaced when the bearing shows wear, pitting, or excessive play, or during routine hub maintenance. Replacing the inner bearing and its race helps prevent hub wobble, overheating, and potential axle damage. Note: this kit typically does not include the outer bearing (LM67048) or grease seal—those must be sourced separately to complete the hub rebuild.
