To find the correct size, you must consult your Dakota's owner's manual or a repair manual specific to your truck's year and model. Alternatively, you can:
* Visually inspect the nut: Measure the nut with a caliper or compare it to a wrench set to determine the size.
* Check a parts store: Take the nut to an auto parts store (like AutoZone, NAPA, or O'Reilly's). They can identify the size for you.
Do not attempt to guess or use the wrong size nut. Using the incorrect size can damage the axle, potentially leading to serious consequences.
