The 1985 Chevrolet Corvette has rear-wheel drive, and the only connection between the rear axle and the transmission is the drive shaft. Servicing the transmission or the rear end often requires pulling out the drive shaft, which can be done in under an hour with the proper tools.
Tools Used: Jack, Jack stands, Drain pan, 3/8-inch ratchet, extension and socket set, 2-foot-long wooden block
Remove Drive Shaft
Lift the car using the jack and support it on all four corners using the jack stands. Make sure it is secure before working under the car.
Unbolt the exhaust system from the exhaust manifold using the 3/8-inch ratchet, extension and sockets. Continue unbolting the exhaust system and removing it in sections. Pull the entire exhaust system out from under the Corvette. Unbolt the parking brake front cable guide from the drive shaft support, about midway down the length of the vehicle, using the ratchet.
Place the wood block on the pad on the jack. Place the jack underneath the transmission pan and raise the jack until it just contacts the transmission pan.
Place a drain pan under the end of the transmission to catch any transmission fluid that may spill out from the transmission once the drive shaft is removed. Unbolt the drive shaft from the rear end at the pinion, which is in the middle of the rear axle, using the 3/8-inch ratchet and socket. Then pull it off the pinion on the rear end using your hands and rest it on the ground. This will leave only the forward end of the drive shaft sitting inside the rear of the transmission. Pull the drive shaft out from the back of the transmission.
