This is a nylon slip yoke plug (also called a driveshaft end plug or welch plug) designed to seal the open end of a splined slip yoke on heavy-duty truck drive shafts.
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 keeps grease inside the splines and prevents dirt, water, and debris from entering, which could accelerate wear. A small vent hole allows pressure equalization without leaking lubricant. Replace this plug if it is missing or damaged to protect the driveline splines.
