To replace the rear main seal, you'll need to remove the oil pan. It may be necessary to disconnect the exhaust pipe at the manifold to allow enough room. once the oil pan is off, find the #7 main bearing cap (nearest the rear of your Jeep) and remove the two bolts that hold it in. half of the rear main seal should come off with the bearing cap, leaving the other half still trapped between the crankshaft and the engine block. you can remove this half by pushing on one end of it with a sturdy, yet flexible instrument, like a popsicle stick, or even a soft punch. when the seal starts to rotate out of it's groove, it can be carefully pulled out with pliers. Bear in mind the Rear main seal is nothing but a rubber coated metal ring about 4# in diameter, and half the thickness of a pencil, and is split into two pieces to allow installation and removal. BE VERY CAREFUL to install the new one facing in the right direction, otherwise your engine will leak profusely!
Installation is fairly straight-foreward. grease up the upper half of the seal, and push it carefully into place, insert the lower half into the main bearing cap, and bolt your jeep back together. be sure to correctly torque all internal engine parts, and oil pan bolts as per your service manual

Why would water be leaking under the dash on 2002 jeep wrangler sport with hard top after a rain?
My 2002 Wrangler came from the factory with the same problem. There is a seal or gasket around the main body or "Tub" -around the fire wall or top of the hood-and it was leaking there and dripping under the dash. They had a factory rep replace it and it hasn't leaked since. The other possibility that older Wranglers have is they leak at the gasket under the windshield, but the 2002 seems a bit young for that so the other is more likely in my opinion.
