  Q: How do oil leaks occur from the Output Shaft Seal (extension housing oil seal) and the speedometer drive gear oil seal, and how are they replaced on Mitsubishi Montero?

  A:

  Oil leaks are usually caused by wear in the extension housing oil seal or the speedometer drive gear oil seal and O-ring. Replacement is a simple matter that usually does not require the transmission or transfer case to come out of the vehicle. The oil seal for the extension housing is located at the back of the transmission or transfer case, where the driveshaft connects. Put the vehicle securely on jack stands to check for leakage as seal leaking will cause loss of transmission lubricant which will collect on the front of the driveshaft and may leak from the rear To start repairing, lightly hit the dust shield (if present) to remove it without deforming it. After that, extract the oil seal from the rear of your transmission or transfer case using either a screwdriver or a pry bar. Be careful not to gouge the splines on the output shaft. In case of difficulty in removal, special oil seal removal one might be Required. For proper installation, place a large pipe or deep socket on the oil seal to ensure that it is driven square and fully home. In order to secure the dust shield in place, tap the dust shield into place. Use some lightweight grease and lubricate the splines of the output shaft and driveshaft sleeve yoke. Then, install the driveshaft while ensuring that you do not damage the lip of the new seal. The extension housing has the speedometer gear housing that is on the side. Check the area for transmission lubricant to find out if any O-ring is leaking. Remove the speedo cable case from the body. Mark the speedo gear casing in relation to the extension casing. Remove the bolt and withdraw the casing. In conclusion, before reinstalling the gearbox cover apply a new O-ring on the driven gear shaft.
