1. Safety First:
* Jack up the vehicle safely: Use jack stands to support the vehicle securely. Never work under a vehicle supported only by a jack.
* Disconnect the battery: This prevents accidental shorts.
* Wear safety glasses and gloves.
2. Axle Removal (Generally Necessary):
* You'll likely need to remove the axle from the differential housing before you can access the C-clip. This involves:
* Removing the brake rotor and caliper: Support the caliper with a bungee cord or wire to avoid straining the brake line.
* Removing the axle nut: This requires a large socket and often a breaker bar or impact wrench.
* Disconnecting the ABS sensor (if equipped).
* Removing the axle from the differential: This often involves some persuasion; use a slide hammer or other appropriate tool to gently tap it out. Be cautious not to damage the axle shaft seals.
3. C-Clip Removal:
* Once the axle is out of the differential: You'll have access to the C-clip on the inside of the differential housing.
* Locate the C-clip: It's a relatively small, usually steel, retaining clip that holds the axle in place.
* Use the correct tool: A small, flat, and strong screwdriver or a specialized C-clip pliers are typically needed. Be careful not to damage the C-clip itself.
* Gently pry or squeeze the C-clip: Carefully work the C-clip out of its groove. It's usually held in place by friction; once you start it moving, it should come out relatively easily. Avoid bending the C-clip; if it's damaged, replace it.
4. Reassembly:
* Reverse the removal process: Carefully install the new C-clip (if necessary), reassemble the axle, and torque all fasteners to the manufacturer's specifications (found in your repair manual).
Important Considerations:
* Repair Manual: A factory service manual for your 2006 Chevy Tahoe is crucial. It provides detailed diagrams and torque specifications necessary for proper repair.
* Special Tools: You may need specialized tools for axle removal and C-clip removal.
* Professional Help: If you're uncomfortable performing this repair, take your vehicle to a qualified mechanic. This is not a beginner-level repair. Incorrectly reinstalling the axle or C-clip can lead to serious damage.
