If you plan on doing the work yourself, your best bet is to purchase a Haynes or Chilton manual. These books explain in detail how to disassemble and reassemble parts of your engine, info on brakes, tuneups, has all your specifications, and just about all the info you would need to work on your vehicle. The parts are easily found at your local auto parts store, and are relatively inexpensive. You also may be able to research replacing the front and rear seals on your engine online, but your best bet would be to have one of the repair manuals I previously mentioned. If you decide to have a garage do the work, it would also be wise to get more than one estimate to do the work.
