1. take belts off
2. with a 27mm socket, pop the crank pulley bolt, either put the car in 5th or use an impact wrench
3. with a 6″ pulley puller and the bolt loosened out almost completely, tighten the bolt on the puller while keeping the crank bolt stationary.
4. When the crank pulley is about an inch or two away from the front cover, you should be able to wiggle the crank pulley off.
5. Around the crank, you’ll see a rubber seal, that’s your front main seal. With a small flat head screw driver, pry it out of its groove but be careful not to score the mating surface on the front cover or the crank.
6. position the new seal in its place. With a rubber mallet, you can tap the new seal in place.
7. put the crank pulley back on, torque to 100 ft-lbs (verify this number, I’m pulling it from the top of my head and could be wrong).
8. put your belts back on
1. pull the driveshaft
2. if you haven’t drained the fluid from the tranny, you can start cussing from the fluid draining out the back. Otherwise proceed to start removing the transmission.
3. You’ll see a pressure plate/clutch disc/flywheel (MT) or a flexplate/torque converter (AT) assembly staring you in the face. Remove these parts and now you’ll see a big O. That’s the main seal for the back.
4. again with the small screw driver, pry the seal out but be careful not to score the mating surfaces.
5. Tap in with a rubber mallet or suitable tool.
6. Put back on the flywheel/clutch/pressure plate assembly or flexplate/torque converter assembly.
7. sucker a bunch of friends to hold up the tranny while you tell em which way to move it around to get the transmission on.
8. offer beers to keep them from killing you and put the driveshaft on.
9. fill up fluids for the tranny
