Internal oil leaks can result from the deterioration of the wheel seals; replacement of the seals can be done independently of the transaxle removal. These seals are on the two sides of the transaxle between the inner Constant Velocity (CV) joints and the differential. Another common test for leakage is to raise the car and place it on jackstands; if the seal is leaking, some fluid will be on the side of the transaxle. Drain the transaxle lubricant first, remove the driveaxle; if the right side wheel seal is to be replaced, then remove the intermediate shaft as well. To remove the right side seal, use a screwdriver or prybar and gently leverage it out of the transaxle bore; however, if the seal is stubbornly stuck, then there is a special tool for this purpose. Finally, if the carrier flange is from the left side seal, remove the old bolt and just throw it away, then screw in the new ones provided. For instance, it is possible to use a screwdriver or prybar to remove the wheel seal from the carrier flange; it is also possible to take out the O-ring from the groove on the rear side of the carrier flange. Fit the new wheel seal into position by using a seal driver or a large deep socket, so as to push or drive the wheel seal squarely into contact with the transaxle case or carrier flange and lubricate the lip of the new seal with multi-purpose grease. Typically, for the left side seal, it is required to insert a new O-ring into the groove located at the rear of the carrier and lubricate it; after that, the carrier flange has to be fitted on the transaxle and the new bolts have to be tightened to the specified torque. Last, replace and reinstall the driveaxle, thereby avoiding exerting force on the lip of the new seal, and fill the transaxle with the correct lubricant.
