Oil leaks frequently occur due to wear of the extension housing oil seal and bushing (if equipped), or the speedometer drive gear oil seal and o-ring. Replacement of these seals is relatively easy since the repairs can usually be performed without removing the transmission from the vehicle. The extension housing oil seal is located at the extreme rear of the transmission, where the driveshaft is attached. If leakage at the seal is suspected, raise the vehicle and support it securely on jack stands. If the seal is leaking, transmission lubricant will be built up on the front of the driveshaft and may be dripping from the rear of the transmission. To remove the oil seal and bushing, remove the driveshaft and carefully tap the dust shield (if equipped) to the rear and remove it from the transmission. On cast iron case (heavy duty) five-speed manual transmissions, remove the nut and U-joint flange. Using a screwdriver or seal removal tool, carefully pry the oil seal and bushing (if equipped) out of the rear of the transmission, being careful not to damage the splines on the transmission output shaft. If the oil seal and bushing cannot be removed with a screwdriver or pry bar, a special oil seal removal tool will be required. To install the new oil seal and bushing, use a large section of pipe or a very large deep socket as a drift and drive it into the bore squarely, making sure it's completely seated. Install a new bushing using the same method. Reinstall the U-joint flange and nut (if equipped) and tighten the nut to the torque specifications. Reinstall the dust shield (if equipped) by carefully tapping it into place. Finally, lubricate the splines of the transmission output shaft and the outside of the driveshaft sleeve yoke with lightweight grease, then install the driveshaft, being careful not to damage the lip of the new seal.

Install a new oil seal using an extension seal installation tool or another suitable tool.

These cars utilize two types of drive axles: the C-lock type and the non C-lock type.

When correctly positioned, the face of the oil seal should be flush with the end of the axle housing, and the lips of the seal should be lubricated with gear oil.

1. Install the bearing with the square shoulder facing in, using a bearing driver or a socket with an outside diameter slightly smaller than that of the bearing. 2. Install a new seal and deflector, lubricating the lips of the seal with multi-purpose grease. 3. Carefully drive in the axle shaft with a soft-face hammer. 4. Fill the differential with the proper lubricant. 5. Install the driveaxle and differential carrier splash shield. 6. Install the wheel and lug nuts. 7. Lower the vehicle. 8. Tighten the lug nuts to the proper torque specifications. 9. Check for proper operation.

The final step is to install the axle shaft.

The face of the oil seal should be flush with the end of the axle housing once it is correctly installed.

The splines of the transmission output shaft and the outside of the driveshaft yoke should be lubricated with lightweight grease.

Depending on which seal you're replacing, either the front or rear driveshaft needs to be removed.

To install the new oil seal and bushing, use a large section of pipe or a very large deep socket as a drift and drive it into the bore squarely, making sure it's completely seated. Install a new bushing using the same method.

After adjusting the bearings, the key and retaining ring should be installed.

Pre-lubricate between the lips of the new seal with transmission lubricant and coat the outer diameter with a suitable sealant.

Apply high-temperature grease to the oil seal recess and tap the new seal evenly into place with a hammer and seal installation tool.

It can be pried out using a large screwdriver or the inner end of the axleshaft itself as a lever.

Drive the new seal into position with a piece of tubing as a drift.

After removing the old oil seal, high melting point grease should be applied to the oil seal recess.

Drive the new seal into position using a piece of pipe or a socket as a drift.

The first step is to raise the vehicle for access beneath and set it firmly on stands.

To remove the oil seal and bushing, remove the driveshaft and carefully tap the dust shield (if equipped) to the rear and remove it from the transmission.

1. Loosen the wheel lug nuts. 2. Raise the vehicle. 3. Place it securely on jackstands. 4. Remove the left front wheel. 5. Remove the differential carrier splash shield from under the front axle. 6. Remove the left driveaxle. 7. Drain the lubricant from the front differential. 8. Pull the left axle shaft out with a slide hammer and adapter. 9. Remove the deflector and seal from the differential. 10. Remove the bearing using a slide hammer and bearing remover attachment.

The first step is to remove the axle shaft.

The bearings should be adjusted by tightening the adjusting nut to 50 ft-lbs, then backing it off and tightening it hand-tight.
