Before you begin:
* Safety First: Use jack stands, not just a jack, to support the vehicle. Disconnect the negative battery terminal. Wear safety glasses and gloves.
* Identify the Failed Mount(s): Visually inspect all engine mounts. A failed mount will often show visible cracks, tearing, or significant sagging. You may need to start the engine briefly (with the vehicle securely supported) to feel for excessive vibration which can indicate a bad mount.
* Gather Tools and Parts: You'll need a jack, jack stands, various wrenches (metric), sockets, possibly a torque wrench, a pry bar or similar tool, and a new motor mount(s). Consult a repair manual (like a Haynes or Chilton manual) for your specific vehicle to determine the correct torque specifications for the bolts. You might also need penetrating oil (like PB Blaster) to loosen rusted bolts.
General Repair Procedure (This is a generalized overview. Consult a repair manual for precise details for your Tahoe):
1. Vehicle Preparation: Securely jack up the vehicle and place it on jack stands. Consult your owner's manual or a repair manual for the correct jacking points.
2. Access the Mount: The location and access to each motor mount varies. You'll likely need to remove various components to gain access to the failed mount. This might include:
* Removing air intake components: To access the front motor mounts.
* Removing some undercarriage components (e.g., skid plate): For better access to the mounts.
* Possibly disconnecting wiring harnesses or vacuum lines: To give you space to work.
3. Remove the Failed Mount: This typically involves removing bolts that secure the mount to both the engine and the frame. Penetrating oil may be necessary to loosen rusted bolts. Use a pry bar carefully to help separate the mount from the engine or frame if it's stuck.
4. Install the New Mount: Carefully align the new motor mount and install the bolts. Do not overtighten. Use a torque wrench and follow the specifications in your repair manual to ensure proper tightening.
5. Reassembly: Reinstall any components you removed to access the motor mount. Double-check all connections.
6. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
7. Test Drive: After reassembly, start the engine and check for any unusual noises or vibrations. Take a short test drive to ensure the repair was successful.
Important Considerations:
* Type of Mount: There are different types of motor mounts (hydraulic, solid, etc.). Make sure you get the correct replacement part for your Tahoe. Your local auto parts store can help you identify the correct part using your VIN.
* Repair Manual: Highly recommended. A repair manual will provide detailed diagrams and instructions specific to your 1995 Chevy Tahoe.
* Professional Help: If you're uncomfortable performing this repair yourself, it's best to take your Tahoe to a qualified mechanic. Improperly installed motor mounts can lead to further damage to your vehicle.
This is a general guide, and the specific steps may vary depending on the exact location and type of motor mount needing replacement. Always consult a repair manual specific to your vehicle model year before attempting any repair. Remember to prioritize safety throughout the process.
