Tools You'll Need:
* Jack and jack stands: To safely support the vehicle.
* Wheel chocks: To prevent the vehicle from rolling.
* Socket set: Including sockets the size of your driveshaft's bolts and the U-joint's capscrews (usually 7/16" or ½").
* Wrench(es): To help loosen stubborn bolts. A breaker bar might be helpful.
* Hammer: For separating the U-joint.
* U-joint press or U-joint separator: Makes the job significantly easier; highly recommended. A pickle fork can be used but risks damaging the driveshaft.
* Penetrating oil (PB Blaster, etc.): To loosen rusted or seized components.
* Grease: For the new U-joint.
* New U-joint: Make sure you get the correct replacement part for your Silverado.
Steps:
1. Preparation:
* Secure the vehicle: Safely lift the vehicle and securely support it with jack stands. Engage the parking brake and use wheel chocks.
* Locate the U-joint: Identify the driveshaft containing the U-joint you need to replace. There are typically two U-joints per driveshaft.
* Apply penetrating oil: Liberally spray penetrating oil onto the cap screws of the U-joint and around the yoke. Allow it to soak for at least 30 minutes.
2. Remove the Driveshaft (if necessary): Depending on the specific U-joint location (front or rear, and which driveshaft), you may need to remove the entire driveshaft. This usually involves removing the driveshaft from the differential or transmission. You'll need to disconnect the driveshaft from the differential or transmission using appropriate bolts and possibly a slip yoke tool. Consult a repair manual to know which bolts to remove and the correct procedure. Support the driveshaft to prevent it from dropping.
3. Remove the U-joint Capscrews:
* Use the appropriate socket and wrench (or impact gun) to remove the four cap screws holding the U-joint in place. These will be on the yoke, the part that connects the U-joint to the driveshaft. These screws can be very tight!
4. Separate the U-joint:
* Using a U-joint press or separator: This is the safest and easiest method. Follow the instructions for your specific tool.
* Using a pickle fork (less recommended): Carefully place the tines of the pickle fork between the cap and the yoke. Tap gently with a hammer to separate the U-joint. Be extremely careful not to damage the yoke or the driveshaft. This method carries a high risk of damaging the driveshaft.
5. Installation of the new U-joint: This is essentially the reverse of removal. Use the press or separator to carefully install the new U-joint. Ensure proper lubrication.
6. Reassembly:
* Reinstall the driveshaft (if removed).
* Tighten all bolts to the manufacturer's specified torque.
* Lower the vehicle.
* Check for leaks or unusual vibrations after driving a short distance.
Important Considerations:
* Marking: Before disassembling anything, make a mark to show the correct orientation of the driveshaft and U-joint. This will ensure proper reassembly.
* Safety: Always prioritize safety. Use jack stands, wear safety glasses, and be mindful of the weight of the components.
* Repair Manual: Consult a repair manual specific to your 2000 Chevy Silverado for detailed instructions and torque specifications. This is crucial to avoid damage.
This process can be challenging for someone without mechanical experience. If you're unsure about any step, it's best to seek professional help from a qualified mechanic. Improperly installed U-joints can lead to serious drivetrain problems.
