Question about steering?

Take off the whole assembly bracket and all, if I can remember right, there are a few bolts that you have to get from the other side that hold the pump and resivour to the bracket.
 
you are trying to just get the bracket off the pump (the bracket comes out of the car with the pump)?

if so, Jason is right on. i think it is 3 bolts that hold it in. air tools or a very careful positioning in a vice would work. then the snail should come off.

good luck.
 
On most Mustang 5.0's the pulley must be removed from the pump to get the pump out of the bracket. You need a puller. Most parts stores carry them.

The whole assembly will come off the engine together though. Then you can take it to a parts store or shop to remove the pulley, if you need the bracket.
