Here's a general overview. Specific steps may vary slightly depending on whether you're removing the front or rear driveshaft. Consult a repair manual specific to your 2005 Tahoe for detailed instructions and diagrams. This is crucial as there can be variations based on trim level and options.
Tools You'll Likely Need:
* Jack and Jack Stands: Safely support the vehicle. Never work under a vehicle supported only by a jack.
* Wheel Chocks: To prevent the vehicle from rolling.
* Socket Set and Wrenches: Various sizes will be needed.
* Torque Wrench: To properly tighten bolts after reassembly.
* Penetrating Oil (PB Blaster, etc.): To help loosen rusted or seized bolts.
* Hammer and Punch (possibly): To help break loose stubborn bolts.
* Drain Pan: For any fluid that might spill.
* Gloves and Safety Glasses: Protect yourself.
* Repair Manual (Highly Recommended): Provides specific torque specs and procedures for your vehicle.
General Steps (Again, consult your repair manual for specifics):
1. Safety First: Disconnect the negative battery terminal. Place the vehicle on jack stands securely. Engage the parking brake and use wheel chocks.
2. Locate the Driveshaft: Identify the driveshaft you need to remove (front or rear).
3. Disconnect the Driveshaft:
* U-Joints: You'll likely need to separate the driveshaft from the differential and transfer case (or transmission) using U-joints. This involves removing retaining clips or bolts on the U-joints. Penetrating oil is your friend here. You may need to use a hammer and punch to gently tap out the clips.
* Slip Yoke: Some driveshafts use a slip yoke. This will require separating the yoke from the transmission or transfer case.
4. Support the Driveshaft: Once the U-joints or slip yoke are disconnected, carefully support the driveshaft to prevent it from falling.
5. Remove the Driveshaft: Once all connections are broken, carefully lower the driveshaft.
Reassembly:
Reassembly is the reverse of the removal process. Be sure to use the correct torque specifications when tightening bolts. Incorrect torque can lead to premature failure and dangerous situations.
Important Considerations:
* Fluid Leaks: Removing the driveshaft might cause some fluid to leak from the differential or transmission. Have a drain pan ready.
* Alignment: If you're working on the front driveshaft, it might be necessary to have a wheel alignment afterward.
* CV Joints (Front Driveshaft): The front driveshaft typically uses constant velocity (CV) joints. These are more complex than U-joints.
This is a simplified overview. A detailed repair manual specific to your 2005 Chevrolet Tahoe is absolutely essential for completing this task safely and correctly. Improper removal or reinstallation can lead to serious damage or injury. If you are not comfortable performing this task, take your vehicle to a qualified mechanic.
