Will a 2002 dodge 1500 2wd steering knuckle fit on 1999 2wd?

Most likely, yes. The 1999 and 2002 Dodge 1500 2WD trucks shared very similar, if not identical, front suspension components. However, there's always a small chance of a minor variation depending on specific trim levels or any factory changes Dodge might have introduced during that production run.

Before you assume compatibility:

* Double-check the part numbers: The most reliable way to confirm compatibility is to get the part numbers for the steering knuckle from both trucks (from a reputable parts website or the knuckle itself) and compare them. Identical or very similar numbers strongly indicate compatibility.

* Consider the VIN: The Vehicle Identification Number (VIN) can provide crucial details about your specific truck's configuration. Using the VIN with an online parts lookup tool can be highly accurate.

While highly probable, always verify part numbers before purchasing and installing to avoid any potential issues.
