The wiper arms on the Nissan Frontier are mounted differently than many cars, and the splines on the wiper motor arm are fairly thin, meaning that the wiper arms may need to be replaced on a regular basis. Although it's not difficult to remove the arms, putting them on has to be done in a specific manner, or you risk stripping out the arms again. In this case, the project vehicle is a 2003 Nissan Frontier, but the process is similar for other vehicles as well.

Step 1

Use the flathead screwdriver to pop open the plastic cap on the end of the wiper arm, at the base near the cowl. Unbolt the arm from the wiper motor using a 3/8-inch ratchet and socket.

Step 2

Grab the arm at the end near the wiper blade and pull it toward the hood so that the arm is at a 90-degree angle to the windshield. Pull on the wiper arm from the base and pull it away from the wiper motor.

Step 3

Place the replacement arm onto the wiper arm motor and then bend the arm at the end with the wiper blade to put the arm at a 90-degree angle to the windshield. The base of the wiper arm should click into place at this point, aligning the splines with the motor. Bolt the wiper arm to the motor using a 3/8-inch ratchet and socket. Bend the arm back flat onto the windshield.
