- The manual transmission in your Hyundai Elantra uses a clutch to engage and disengage the power from the engine to the transmission.
- The clutch disc is sandwiched between the engine flywheel and the transmission pressure plate.
- When you switch gears and let off the clutch pedal, there is a short period during which the clutch is slipping to transmit the power in a controlled way. This causes wear on the clutch; over time it will require replacement.
The procedure to replace the clutch is as follows:---
1) Jack up the Hyundai Elantra and place on jack stands.
2)Drain the transmission gear oil into a catch pan. To drain the gear oil, loosen the drain bolt with a ratchet.
3)Disconnect both drive axles (half shafts) from the transmission. Use a ratchet to remove the two bolts that hold the steering knuckle to the strut. Once those are out, you can easily pull the axles out of the transmission. The steering knuckle is the component that the wheel and strut attach to.
4)You can locate the two bolts to remove by following the strut down from where it's bolted into the engine bay Removing these two bolts allows you to pull the steering knuckle outward so you can pull the drive axle out of the transmission.
5)Remove the exhaust downpipe from the rest of the exhaust. It will be held on with two bolts at both ends and can be removed with a ratchet. Removing this piece is necessary to gain access to the transmission.
6)Disconnect the shifter cables connected to the transmission. Use a ratchet to remove each shifter cable and its housing.Remove the bolts holding the transmission to the engine block (there will be about seven or eight bolts). Place a transmission lift underneath the transmission to hold it and lower it down. If you don't have a transmission lift, you can use a transmission attachment for your jack.Shift the transmission back and forth until it drops onto the jack. Pull the transmission straight back, ensuring that no pressure is put on the input shaft, then lower the transmission to the ground. 7)Remove the pressure plate and clutch disc from the flywheel with a ratchet tool. Then remove the flywheel with a ratchet tool and replace it with a new flywheel. Alternatively, have your flywheel professionally machined at a machine shop then replace it in your car. Torque the flywheel down to the manufacturer's specifications.
8)Place the clutch disc on the clutch disc alignment tool and insert the tool into the flywheel input shaft hole. Connect the new pressure plate to the flywheel and torque the bolts. Once the pressure plate is torqued down, remove the clutch alignment tool. 9)Grease the new throw-out bearing and place it on the input shaft of the transmission. Once the transmission is installed, it will push against the pressure plate.
10) Reconnect all the parts which you removed while replacing the clutch.
