To replace a flywheel, take out the drive shaft; remove other vehicle components such as the speedometer, shift linkage and cooler lines; and detach the transmission. Then, take the old flywheel out, and replace it with the new one. Finally, reassemble the transmission, vehicle components and drive shaft.
To take the drive shaft out of the vehicle, detach the differential from it. Remove the bolts that secure the drive shaft using a wrench, and pull the component out. Keep a drip pan under the point of contact between the drive shaft and transmission to collect the fluid that leaks out from the transmission. To remove the cooler lines of the transmission and the speedometer cable, use a wrench. Use a flare-nut wrench to disconnect the line of the shift linkage. To disconnect the transmission, first position a transmission jack below it. Raise the jack until the transmission sits securely on the oil pan. Then, undo the retaining nuts that secure the transmission to the engine block. Shift the transmission towards the rear side of the vehicle. The flywheel should now be visible.
Next, undo the retaining bolts of the flywheel, located usually at its center, using a wrench. Pull the flywheel gently to detach it from the crank shaft. Position the new flywheel, and secure it using the retaining bolts. When reattaching the transmission, ensure the torque converter is aligned appropriately with the flywheel's holes. Replace the housing of the transmission using the retaining nuts, and reconnect the speedometer, cooler and shift linkage lines. After reassembling the drive shaft, replace the transmission fluid, and run the vehicle to check for proper flywheel installation.
