Safety First: Precautions to Take
Before you start working, disconnect the negative terminal of your car’s battery to prevent any electrical accidents. Also, make sure to wear safety glasses and gloves to protect yourself from any debris or chemicals.
Locating the Wiper Linkage Bushings
The wiper linkage bushings are located on the wiper linkage arms, which connect the wiper motor to the wiper blades. To access the bushings, you will need to remove the wiper arms.
Removing the Wiper Arms
1. Release the wiper blades: Push down on the wiper blades and slide them off the wiper arms.
2. Locate the wiper arm bolts: On most vehicles, the wiper arms are held in place by bolts or nuts. Locate these bolts and loosen them using a socket wrench.
3. Pull the wiper arms off: Once the bolts are loose, gently pull the wiper arms straight up and off the wiper linkage shafts.
Disconnecting the Linkage from the Motor
Once the wiper arms are removed, you will need to disconnect the wiper linkage from the motor.
1. Locate the linkage pivot point: Find the point where the wiper linkage connects to the wiper motor.
2. Remove the linkage pin: Use a screwdriver or pliers to remove the pin that connects the linkage to the motor.
3. Pull the linkage free: Once the pin is removed, gently pull the linkage away from the motor.
Removing the Wiper Linkage Bushings
Now that the linkage is disconnected from the motor, you can remove the wiper linkage bushings.
1. Spray with penetrating oil (optional): If the bushings are stuck, you can spray them with penetrating oil to loosen them up.
2. Use a socket wrench to remove the bushings: Use a socket wrench to loosen and remove the bolts that hold the bushings in place.
3. Pull the bushings off: Once the bolts are removed, gently pull the bushings off the linkage arms.
Installing the New Bushings
With the old bushings removed, you can now install the new ones.
1. Slide the new bushings onto the linkage arms: Slide the new bushings onto the linkage arms and make sure they are fully seated.
2. Tighten the bolts: Tighten the bolts that hold the bushings in place using a socket wrench.
3. Reconnect the linkage to the motor: Insert the linkage pin back into the pivot point and reconnect the linkage to the wiper motor.
Reattaching the Wiper Arms
1. Slide the wiper arms back onto the shafts: Slide the wiper arms back onto the wiper linkage shafts.
2. Tighten the bolts: Tighten the bolts that hold the wiper arms in place using a socket wrench.
3. Reattach the wiper blades: Slide the wiper blades back onto the wiper arms.
Final Checks and Testing
Once the wiper linkage bushings are replaced and the wiper arms are reattached, perform the following checks:
- Check for proper movement: Manually move the wiper arms to make sure they move smoothly and without binding.
- Test the wipers: Turn on the wipers and make sure they operate properly.
Wrapping Up: A Smooth and Safe Ride
By following these steps, you can successfully remove and replace the wiper linkage bushings on your car. This simple repair will ensure that your wipers operate smoothly and effectively, keeping your windshield clear and your driving experience safe.
