Oil leaks are due to worn of extension housing oil seal and bushing or the speedometer drive gear oil seal and O-ring. The general rule of thumb for these seals is that the repair is straightforward; in most cases, the seals can be changed without having to pull the transmission from the car. The extension housing oil seal is located at the rear of the transmission at the driveshaft connection. If leakage is suspected the vehicle must be raised off of the ground on jackstands securely. A leaking seal will cause transmission lubricant to be present on the front on the driveshaft and dripping at the rear of the transmission. In order to remove the oil seal one has to use the screwdriver or pry bar while being as careful as possible to avoid damaging the splines of the transmission output shaft. If removal is challenging, a further set of special oil seal removal tool might be needed. When fitting the new oil seal use a large pipe or deep socket as a drift to ensure that the oil seal is properly aligned and married to the bore. Before fitting the driveshaft back in, a thin grade of grease should be applied on the splines of the transmission output shaft and the outer diameter of the driveshaft sleeve yoke without putting any pressure on the new seal's lip. The speedometer cable with the driven gear housing will be situated on the side of the extension housing; examine for signs of transmission oil around the cable housing for signs of leakage of the seal and O-ring. Remove speedometer cable connector if available, and with a hook pry out the seal. Last, place a new O-ring in the driven gear housing then put back the driven gear housing with the cable assembly to the extension housing.

Oil leaks can occur due to wear of the extension housing oil seal and bushing, as well as the speedometer drive gear oil seal and O-ring. These seals can be easily replaced without removing the transmission from the vehicle. The extension housing oil seal is located at the rear of the transmission where the driveshaft is attached. If leakage is suspected, the vehicle should be raised and supported securely on jackstands. The oil seal can be pried out of the transmission using a screwdriver or pry bar, or a special removal tool may be required. The new oil seal should be installed using a large socket or pipe as a drift. The splines of the transmission output shaft and the outside of the driveshaft sleeve yoke should be lubricated with lightweight grease before installing the driveshaft. The speedometer driven gear housing or vehicle speed sensor is located on the side of the extension housing. To remove it, the speedometer cable or electrical connector should be disconnected, and the hold-down bolt should be removed. The seal and O-ring can be checked for leaks by looking for transmission oil around the cable housing. The vacuum modulator O-ring can be replaced by removing the vacuum line, hold-down bolt, and modulator. The old O-ring should be removed and the new one should be coated with clean ATF before installation. The manual lever also has a seal, but it is recommended to take the vehicle to a qualified repair shop for replacement. To replace the manual lever seal, the shift linkage should be disconnected and the old seal should be pried out using a small hooked tool. The new seal should be driven into place using a deep socket and hammer. The shift linkage should be reconnected and adjusted before refilling the transmission. Finally, the vehicle can be lowered by removing the jackstands.

Raise the vehicle and support it securely on jackstands. Remove the driveshaft. Use a seal removing tool to take out the oil seal from the end of the extension housing, or alternatively, a wide-bladed screwdriver or chisel can be employed to carefully tap around the flange of the oil seal and separate it from the transmission extension housing. Before installing the new seal, inspect the sealing surface of the universal joint yoke for scoring; if any scoring is found, replace the yoke. Check the counterbore of the housing for burrs and remove them with emery cloth or medium grit wet-or-dry sandpaper. Coat the outside diameter of the seal with RTV sealant. Install the new seal into the extension housing using a large socket or length of pipe of the proper diameter, or a blunt punch and hammer can also be used to tap the new seal into the bore. The remainder of the installation follows the reverse of the removal procedures.

Leakages are usually caused by wear of extension housing oil seal and bushing, speedometer drive gear oil seal and O-ring. These seals can be replaced with ease most of the times without the need for the transmission to be unmounted from the car. The extension housing oil seal is placed at the rear extension housing area where the driveshaft joins with the transmission. Where there is suspicion of leakage, the vehicle should be jacked up and properly supported in order to gain access to the underside of the car. Some signs of a leaking seal are: transmission lubricant on the driveshaft and there can also be dripping from the back of the transmission. To replace the oil seal, it is necessary to pull out the driveshaft, then the oil seal can be pulled out with a screwdriver or pry bar, being very careful not to harm the splines of the transmission output shaft. If required, then Konmaru Special Oil Seal Remover can be employed for its removal as aforesaid. A sector of pipe or deep socket can also be used to install new oil seal guaranteeing that this is driven squarely and to the end. The splines of the output shaft of the transmission and the outer periphery of the sleeve yoke should be lubricated with light lubricants before the reinsertion of the driveshaft to prevent the damaging of the new lip seal. In the case of the speedometer driven gear housing or vehicle speed sensor mounted on the side of the extension housing, the speedometer cable or electrical connector is disconnected first, then the hold down bolt. Dipping a finger in transmission oil around the cable housing is a sign of compromise on the seal or O-ring. The seal can be pulled out with a hooked tool, when reassembling the driven gear housing and cable assembly a new O-ring should be placed into the driven gear housing .

Raise the vehicle and support it securely on jackstands. Drain the transaxle fluid if the filler plug is higher than the lowest part of the seal to prevent fluid loss during seal removal. Mark the rear driveshaft to transfer case yoke orientation, remove the driveshaft from the yoke and swing it out of the way. Remove the driveshaft at the rear axle and slide the driveshaft out of the transfer case extension housing. Hold the rear yoke with a suitable tool and remove the center retaining nut. Remove the yoke nut and washer. Remove the yoke and slinger from the transfer case rear output shaft. Remove early model non-flanged seals with a slide-hammer and adapter or carefully pry the seal out of the case bore with a blunt screwdriver. Remove later model flanged seals using a seal remover and slide hammer or tap out an edge of the seal using a dull screwdriver. Inspect the oil seal contact surface on the case for scoring or burrs and remove them with emery cloth or fine sandpaper. Apply multi-purpose grease to the oil seal and position it squarely into the case bore. Drive the seal squarely into the bore using an appropriately sized seal driver, large socket, or pipe section. Clean the yoke splines and lubricate lightly with multi-purpose grease, then slip the slinger and yoke over the output shaft and carefully past the new seal until it bottoms. Coat the face of the yoke retaining nut with RTV sealant and apply thread locking compound to the threads. Install the rubber seal, washer, and yoke retaining nut onto the output shaft. Tighten the retaining nut to the torque. Install the rear driveshaft. Check and refill the transfer case lubricant as necessary. Remove the jackstands and lower the vehicle. Shift out of 4WD and unlock hubs before returning the vehicle to normal service.

To perform a fuel pressure test, follow these steps: 1. Obtain a fuel pressure gauge and adapter set (fuel line fittings). 2. Relieve the fuel pressure. 3. Lay a shop towel over any fuel connection to be disassembled to absorb the residual fuel. 4. Check the fuel system's delivery by listening at the fuel filler opening while an assistant turns the ignition key to the On position (engine not running). 5. If no sound is heard, check the fuel pump fuse, relay, and circuit. If the issue persists, there may be a problem in the fuel pump circuit or a faulty fuel pump. 6. Check for battery voltage to the fuel pump relay connector and power relay connector. If present, have the relays tested at a qualified automotive repair shop. 7. If no voltage is present, check the fuses and wiring circuit. 8. For the operating pressure check, attach the fuel pressure gauge to the test port and activate the fuel pump without starting the engine. 9. Note the fuel pressure and measure it again with the engine idling. 10. Detach the vacuum hose from the fuel pressure regulator to check for an increase in pressure. 11. If pressure is too high or low, inspect and replace components accordingly.
