Depending on the car or truck the engine may or may not need to be removed from the car.
Drop the oil pan
There are both one and two piece seals available to repair this. If the engine is removed from the car remove all main bearing caps lift the rear of crank and slip the old seal off and install new.
If the engine is still in the car or connected to the trans remove the rear bearing cap and remove the old seal. If it a two piece it will just roll out ( with a fair amount of force and swearing), if it is a one piece it will need to be cut and have the new seal rolled (slid in )
Reassemble in reverse of disassembly.

Not really, you need to drop the oil pan to get to the rear main. You may be able to install a new seal by dropping the cap for the rear main. You may have to loosen all the main caps and pull the crank down just a bit. Install the seal and re-torque the main caps.
