First things first Make sure you have turned the main water valve to your house off.
Then Open a faucet (if possible at a lower level then the faucet being repaired) and make sure it stays open. This will prevent any water that is getting past the valve or is just in the lines from running in to the wall . Click on a thumb nail to see the picture larger. |

First remove the Handle. remove the plastic cover and remove the screw. |
Then remove the two screws that hold the Chrome Plate and remove the plate. Note: This step is not necessary. The faucet can be repaired with out removing the chrome plate. |
|
 |
 |
Then remove the pin that holds the cartridge in. Just pull up with needle nose
pliers. Note the position of the cartridge. This can be a point of no return. If you are not sure you should continue Call a professional

There is a tool for removing the cartridge but I just put the handle back on and use it to pull the cartridge out. Note: Sometimes a cartridge will not come out no mater what you do, If this happens you may want to stop and call a professional

This happens more when you have very hard water. In a case like that it is best to stop before you damage the faucet, put the pin back in and go shopping for a new faucet |

pics were helpful. But, I couldn't get my cartridge out by pulling on it with
handle (or prying). You indicate only hope is replace faucet which means tearing
into wall , soldering pipes, etc - big job.
Home Depot had a Moen stem pulling tool for $12.97 that did the job.
made by 'Brass Craft' T161 - 'Stem and Cartridge wrench for Moen faucets')
If the handle trick fails I think you should try this
tool.

Before putting the new one in, clean out the inside of the faucet and apply a little plumbers grease to the walls of the faucet and on the new cartridge. then slide it in. Make sure it goes all the way in. |
Note the position of the cartridge, It must be in this position. |
 |
 |
But before you put the cover over the handle screw test to see if the hot is on the left or not if it is on the right remove the handle and turn the stem 180% (you don't need to remove the pin or cartridge to do this) |
| Replacing the pin. This must be done right, It has to go straight through and into the bottom slot.
|
It must look like this all the way in and not bent at the bottom. Now you are done. put back the sleeve, the chrome plate. and turn the water back on, |
Then put the handle back on and you are done. Good Luck.
