Replacing the clutch on a Golf Mk4 is a common procedure, with over 500,000 of these vehicles on the road. The process involves removing the transmission and cleaning the clutch assembly, and it is not considered to be very difficult if you have some knowledge and guidance. This job can be carried out without any special tools, although some additional equipment is required, such as a transmission jack and an engine support cradle. It is also important to take safety precautions, such as disconnecting the battery earth lead before starting work.

What You'll Learn
Removing the transmission
Step 1: Prepare the Vehicle
Safely jack up and support your vehicle. Make sure you have the necessary tools and equipment, such as a floor jack and an engine hoist. Volkswagen considers all of the mounting hardware to be single-use only, so ensure you have new hardware before beginning.
Step 2: Access the Transmission
Remove the adjustable ends to the shift cables. Take out the three 13mm bolts holding the cable mount to the transmission. If your clutch is functioning properly and you are not replacing the slave cylinder, leave the hydraulic line attached. Otherwise, unclip the clutch hydraulic line from the mount.
Step 3: Remove Surrounding Components
Loosen but do not remove the 18mm bolt on the upper rear mount. Remove the 13mm nut and ground wire attached to the upper centre bolt. Then, loosen but do not remove the 18mm bolt it was attached to. Remove the starter motor.
Step 4: Disconnect the Transmission
Loosen and remove the 18mm bolt on the right side of the transmission case by the flange. Remove the six bolts from the left side axle to flange and tie the axle up out of the way. Remove the 16mm bolt holding the power steering cooling line to the transmission case. Loosen but do not remove the two 16mm bolts joining the bell housing to the engine case.
Step 5: Final Steps Before Removal
Remove the bog bone mount. Support the engine from an engine hoist above or from a jack below. You will need to lower the engine slightly when separating the transmission, so ensure you have the necessary clearance.
Step 6: Remove the Transmission
With the help of your friends, carefully separate and lower the transmission from the vehicle. Take your time and work safely, as this is a heavy component.
Remember that installation is the reverse of removal. When reinstalling, take your time and use all new mounting hardware.

Cleaning the bell housing
To clean the bell housing of your Mk4 Golf, you'll need to remove it from the engine bay and give it a thorough clean. Here's a step-by-step guide on how to do it:
First, locate the bell housing on your Golf. It's the metal cover that surrounds the clutch and flywheel at the back of the engine. You'll need to remove it to access and clean the area properly. Make sure you have a workspace large enough to lay the housing down and disassemble it safely.
Protect your work area with a tarp or old newspapers, as the cleaning process can be messy. Gather your tools and cleaning supplies, including a set of wrenches, screwdrivers, a parts cleaner or degreaser, and some clean rags or shop towels. Wear protective gear, such as gloves and safety goggles, to shield your skin and eyes from debris and chemicals.
Begin by disconnecting the negative battery terminal to prevent any accidental electrical discharges. Next, support the engine with a jack or hoist, ensuring it's secure and stable. Remove the bolts attaching the bell housing to the engine and transmission, carefully lifting it away from the vehicle. Place the bell housing on a workbench or flat surface.
Using your wrench and screwdriver, carefully disassemble the bell housing into its component parts. This will allow you to access all the nooks and crannies for a thorough cleaning. Soak the components in a parts cleaner or degreaser to break down any built-up grease, oil, and grime. Use a stiff brush or rag to scrub away any remaining residue.
Once the parts are clean, rinse them with a solvent or cleaner to remove any chemical residue from the cleaning process. Dry the components thoroughly with compressed air or a clean rag. Reassemble the bell housing, ensuring that all components are correctly torqued and aligned.
Finally, reinstall the bell housing onto the engine and transmission, carefully reversing the removal process. Secure all bolts and connections, lower the engine, and reconnect the negative battery terminal. Your bell housing should now be clean and ready for further maintenance or installation of a new clutch. Remember to dispose of all cleaning chemicals and waste appropriately, following local regulations.

Replacing the clutch release bearing
Firstly, you will need to identify the source of the problem. If you are experiencing a nasty grinding, clunking noise when in neutral, it is likely that the release bearing is worn out. If the pedal becomes very heavy and stiff, this further indicates that the release bearing needs to be replaced.
To replace the release bearing, you will need to remove the transmission. This is a big process, but it is not a super-difficult job if you have some guidance. You will need to remove the clutch release fork, or lever, by taking out the metal clip that holds it to the pivot ball. Then, lift the lever and release bearing off of the transmission shaft. Compress the retainer clips on the old release bearing and remove it from the pivot arm. Next, snap the new release bearing into the arm, ensuring the snap clips lock in place. Apply a small amount of assembly lube to the splines on the input shaft, on the sleeve surrounding the shaft, and on the pivot stud.
It is recommended that you replace other worn parts while you have the transmission out, to save you from having to remove it again in the near future.

Reinstalling the transaxle
First, make sure that all electrical cables and connectors are disconnected. Then, slowly lower the transaxle, ensuring that it clears the engine and chassis simultaneously. Some minor wiggling may be required.
Next, move the transaxle away from the engine, just far enough for the transaxle input shaft to clear the pressure plate fingers.
Now, you can begin to retrace your steps to reinstall the transaxle. Due to casting dimension variations, your new flywheel/pressure plate may rub at one or more points inside the bell housing. To avoid this, use the ECS Tuning MK4 bell housing clearance gauge to locate raised casting areas that may cause interference and rubbing.
Finally, torque the ball joint bolts to 20 Nm (15 ft-lb) + 90 degrees. VW recommends replacing several fasteners, including the axle bolts and the three ball joint bolts and three-nut plate for the left ball joint.

Disconnecting the battery
First, it is crucial to turn off the vehicle and remove the key from the ignition. This is an essential safety precaution. Additionally, make sure you are wearing protective gloves and eye gear, as batteries can produce explosive gas and battery acid can be harmful to your skin.
The next step is to disconnect the negative or ground strap first. This is important to prevent any potential damage to the vehicle's electrical system. Locate the negative terminal, which will be marked with a "-" symbol or a black cover. Use a wrench or socket to loosen the nut that secures the cable to the terminal, then carefully detach the cable. Ensure that the cable does not come back into contact with the battery.
Now, you can disconnect the power strap from the main positive lead going to the fuse panel. This is located on the top of the battery and is marked with a "+" symbol or a red cover. Again, use a wrench or socket to loosen the nut and detach the cable.
With both cables disconnected, you can now remove the battery. It is held in place by a 13mm nut and plate at the lower front. Remove this, and then carefully lift the battery out of the vehicle.
It is important to note that you should never disconnect a battery cable while the engine is running, as this can cause damage to the alternator or other electrical components due to a surge in amperage.
