If you own a 2018-2020 Ford Expedition 2WD and have noticed a clunking noise when shifting from reverse to drive or during coast down, you’re not alone. This is a common issue linked to the driveshaft, specifically the spline area. Fortunately, applying grease to the shaft spline can help mitigate this problem. In this blog, we’ll walk you through the process step by step.
Understanding the Issue
The clunking noise in your Ford Expedition is often caused by insufficient lubrication in the driveshaft spline area. When the spline isn’t adequately greased, it can lead to excessive wear and tear, resulting in the noise during shifts. Addressing this issue with the right maintenance can improve your driving experience and extend the lifespan of your vehicle.
What You’ll Need
Before you start, gather the following tools and materials:
- Grease: High-quality, automotive-grade grease
- Grease gun: For applying the grease efficiently
- Socket set: To remove any necessary components
- Torque wrench: To ensure proper tightness
- Clean rags: For cleaning excess grease
- Safety gear: Gloves and safety glasses
Guide to Greasing the Shaft Spline Area
Step 1: Safety First
Before starting any maintenance work, ensure the vehicle is parked on a level surface. Engage the parking brake and wear your safety gear to protect yourself.
Step 2: Lift the Vehicle
Using a jack, lift the rear of the vehicle and securely support it with jack stands. Make sure the vehicle is stable before crawling underneath.
Step 3: Access the Driveshaft
Locate the driveshaft under the vehicle. You may need to remove any protective covers or components obstructing access to the driveshaft. Use your socket set to carefully remove these parts.
Step 4: Inspect the Spline Area
Before applying grease, visually inspect the spline area for any signs of wear or damage. Look for any cracks or excessive rust. If the spline looks compromised, you may need to consult a professional.
Step 5: Clean the Spline Area
Using a clean rag, wipe away any dirt, debris, or old grease from the spline area. A clean surface ensures better adhesion of the new grease.
Step 6: Apply Grease
Using your grease gun, apply a generous amount of grease to the shaft spline area. Ensure that you cover all exposed surfaces, but be careful not to overapply, as excess grease can attract dirt and debris.
Step 7: Reassemble Components
If you had to remove any components to access the driveshaft, reattach them now. Use your torque wrench to ensure everything is tightened to the manufacturer’s specifications.
Step 8: Lower the Vehicle
Once everything is reassembled, carefully lower the vehicle back to the ground. Remove the jack stands and ensure the vehicle is stable.
Step 9: Test Drive
Take your Ford Expedition for a test drive to see if the clunking noise has been resolved. Shift from reverse to drive and coast down to check for any remaining noises.
Applying grease to the shaft spline area of your Ford Expedition can significantly reduce or eliminate clunking noises during gear shifts. Regular maintenance is key to keeping your vehicle running smoothly and efficiently. If you continue to experience issues after greasing the spline, it may be time to consult a professional mechanic for further evaluation.
By taking these proactive steps, you can enjoy a quieter, more comfortable ride in your Ford Expedition for years to come!
