Remove Wheel and Hub: Loosen lug nuts, lift car, remove wheel, and detach hub assembly
Before diving into the CV joint replacement on your Mk1 Golf, you’ll need to safely remove the wheel and hub assembly to access the CV joint. Start by loosening the lug nuts on the wheel you’re working on. Use a lug wrench and turn the nuts counterclockwise, but don’t remove them completely yet. Loosening them while the car is still on the ground ensures the wheel doesn’t spin when you apply force. If the lug nuts are tight, apply some penetrating oil and allow it to sit for a few minutes to ease removal.
Next, lift the car using a jack and secure it on jack stands. Position the jack under the designated lift point near the wheel you’re working on, typically just behind the front wheel on the Mk1 Golf. Once lifted, ensure the car is stable and safely resting on the stands before proceeding. This step is critical for your safety, as working under an unsecured vehicle is extremely dangerous.
With the car securely lifted, remove the wheel by fully unscrewing the loosened lug nuts and setting them aside. Carefully pull the wheel straight off the hub and place it aside, ensuring it’s out of the way but not damaged. Take this opportunity to inspect the brake components and rotor for any signs of wear or damage, as this is a good time to address any additional issues.
The final step in this section is to detach the hub assembly. Locate the bolts securing the hub to the steering knuckle—these are typically located around the perimeter of the hub. Use a socket wrench or appropriate tool to remove these bolts, taking care to keep track of their positions for reassembly. Once the bolts are removed, gently pull the hub assembly away from the knuckle. If it’s stuck, lightly tap it with a mallet or use a pry bar carefully to avoid damaging any components. With the hub assembly detached, you’ll have full access to the CV joint for removal and replacement.

With the CV joint separated from the hub, your next step is to detach it from the axle shaft. Position a drain pan under the joint to catch any transmission fluid that may leak out. Using a flathead screwdriver or a pry bar, carefully lever the CV joint away from the axle shaft. Be cautious not to damage the axle or surrounding components. If the joint is stubborn, you can tap the axle shaft gently with a mallet to help loosen it, but avoid striking the joint itself to prevent damage.
As you work to separate the CV joint from the axle, inspect the axle shaft and joint for signs of wear or damage. If the axle appears bent or the joint shows excessive play, consider replacing the axle as well. Once the joint is free from the axle, clean the area around the axle shaft to remove any dirt or debris that could contaminate the new CV joint during installation. This ensures a smooth and secure fit for the replacement joint.
Before completely removing the old CV joint, take note of its orientation and how it was attached to the axle. This will help you correctly install the new joint. If your Mk1 Golf has a bolted CV joint (some models may vary), remove the bolts securing the joint to the axle using the appropriate socket or wrench. Keep track of the bolts and their positions, as they may need to be reused or replaced during the reassembly process.
Finally, with the CV joint unbolted and separated from both the hub and the axle, inspect the area for any remaining components, such as spacers or clips, that may need to be transferred to the new joint. Clean the hub and axle surfaces thoroughly to ensure proper seating of the new CV joint. This step is crucial for preventing issues like vibrations or premature wear once the new joint is installed. Now you're ready to proceed with installing the replacement CV joint on your Mk1 Golf.
