How do you change a wheel seal on a mercury mountaneer 1998 rear end

Axle Vent
NOTE: If the vent cannot be cleared, it must be installed new.
A plugged vent will cause excessive seal lip wear due to internal pressure buildup. If a leak occurs, check the vent. Make sure the vent hose is not kinked. Remove the hose from the vent nipple and clear the hose of any foreign material. While the hose is removed, pass a length of mechanics wire or a small diameter Allen wrench in and out of the vent to clean it. Connect the hose when done. The vent is located on the drivers side top of axle housing.
If you plan on doing most repairs yourself I would suggest buying a Haynes or Chilton manual for your particular vehicle. Or there are some data disks on e.bay($12-$15) For a cost of under $25, you can almost do any repair yourself with these manuals.Also there are online manuals like the site called ALLDATA where guides can be viewed for a fee. All these solutions will save you time and money, and give peace of mind over correct repairs. I can post you some procedures here also.
